Page 1 RAILBELT STABILITY STUDY PHASE I 10 INTRODUCTION This report covers the first part of a three-part study with the following goals: Phase I Phase II Phase III Define alternative system equipment additions to facilitate delivery of Bradley Lake power to the Anchorage. Select the most cost-effective alternatives proposed in Phase I and optimize to meet all criteria with lowest cost equipment compliment. Prepare preliminary specifications for the series and shunt compensation recommended in Phase II and outline computer and simulator studies required to complete the specifications. The scope of the Phase I studies was fully defined in a meeting in APA offices in Anchorage on December xx attended by Railbelt utilities interested in the project. At this meeting it was agreed that the alternative transmission improvements to be defined in Phase I studies should meet the following requirements: ° Deliver 120 MW from Bradley Lake without power reductions that could cause load shedding when there is little or no spinning reserve. ° Deliver 75 MW from the Kenai area to the Anchorage area, measured on the Dave’s Creek to Portage line. ° Accommodate fault-caused loss of load in the Kenai area. ° Use a three-phase, normally cleared fault as the disturbance criteria. Power Technologies, Inc. Page 2 It was also agreed that the Phase I study would concentrate on development of a transmission plan utilizing only the existing 115 kV lines, but would briefly examine an alternative utilizing a new 230 kV line in order to assess the performance, cost, and reliability differences between 115 and 230 kV alternatives. The analysis to develop a 115 kV plan to meet the above goals was completed in early January, three weeks following receipt of system data. However, the analysis did not provide the desired multiple transmission plan alternatives as had been desired. A complement of series capacitors (3), SVSs (2), a braking resistor, and stabilizers at Bradley Lake was shown to meet the criteria nicely, but left essentially no options for alternatives. With the basic goals of the Phase I study complete, attention was tumed to alternatives involving lower Bradley Lake power levels (90 MW), use of the deflector to improve stability, and a look at the 230 kV option. The stability cases described in this report show that all of the above options are workable, and that there are differences in reliability and cost. 2.0 STABILITY OVERVIEW The most severe disturbance insofar as Kenai stability is concerned is a three-phase fault near Bradley Lake on the Bradley Lake - Soldotna line. The problems it causes include first-swing stability, damping, and steady state stability (See Appendix I for a description of these stability problems). The root cause of these problems is the long transmission path between Bradley Lake and Anchorage that remains following loss of the Bradley Lake to Soldoma line. First-swing stability can be achieved by installation of series capacitors, SVSs, high ceiling - high initial response excitation, braking resistors, generator dropping and generator power reduction (deflector). The deflector and the braking resistor have both been examined for use at Bradley Lake. The braking resistor is very effective. The deflector is less effective in that it "cuts-in" over a period of time rather than being applied suddenly and completely. However, it may be suitable where loading is not much beyond the point of first-swing stability, or where it can supplement the braking resistor. Generator dropping is also a candidate for Bradley Lake, but has been ruled out for frequent use because of the load shedding that is likely to result. Power Technologies, Inc. Page 3 Steady state stability can be reliably and economically provided by use of the deflector. The deflector can bring power down to within the steady state stability limit before the system approaches a steady state condition. However, an SVSs and three series capacitors can provide steady state stability without power reduction and possible consequent load shedding. SVSs have been considered at Anchor Point and Quartz Creek, while series capacitors have been considered between Bradley Lake and Fritz Creek, between Anchor Point and Kasilof, and between Soldotna and Quartz Creek. These are the three longest line sections in the path between Bradley Lake and Anchorage when the Bradley Lake Soldotna line is open. The three lines are well distributed along the path, though this is a secondary consideration. Series capacitors can also be considered for the line from Dave’s Creek to University, even though there are load taps on this line. However, in that instability occurs between Bradley Lake and Soldotna in most cases, the most effective location for series capacitors is between Soldoma and Bradley Lake. Dynamic stability can be improved most economically by stabilizers on the Bradley Lake generators. Where this is not sufficient, SVSs will contribute significantly to dynamic stability, and can be equipped with a stabilizer for maximum benefit. Series capacitors also improve dynamic stability significantly. Where damping is a problem only in the first few seconds of large power swings, the deflector can also contribute to dynamic instability by holding power down for several seconds until the large oscillations have subsided and the oscillations are within the capability of the Bradley Lake stabilizers and the SVSs. Once the large oscillations have subsided (3 to 5 seconds), Bradley Lake power can be ramped up gradually over several seconds.’ The temporary runback can result in load shedding if spinning reserve is low when it is used. Unless otherwise noted, all stability cases discussed below address fault and trip of the Bradley Lake to Soldotna line. The fault is three-phase close to Bradley Lake, and the line is cleared in 4 cycles (.06667s). Power flow plots for base case and post-fault conditions and stability case plots are presented in Appendix II for all cases referenced in the following sections. It is not unusual for nonlinearities in a system to result in dynamic instability for large oscillations and dynamic stability for smaller oscillations. Power Technologies, Inc. Page 4 3.0 NO 230 KV LINE 3.1 120 MW AT BRADLEY LAKE 3.1.1 Base Case Power Flow The base case power flow has the following conditions: ° Bradley Lake at 120 MW ° Bernice Lake # 3 on at 24 MW ° Cooper Lake units on at 15 MW ° Tesoro unit on at 4.5 MW ° Kenai export to Anchorage area 70 MW measured just above Dave’s Creek ° Fairbanks import 70 MW measured just above Cantwell ° Tesoro to Kenai 69 kV line closed ° University to Anchorage 115 kV line closed ° Two University 115-138 kV transformers with reduced tertiary load (load shifted to a new 115-34.5 kV transformer). ° All International Plant units off-line ° Shunt capacitors at Anchor Point, Soldotna, and Quartz Creek The original study plan was to consider a Kenai export of 75 MW measured above Dave’s Creek. However, a second generating unit would have been needed at Bernice Lake to provide the additional 5 MW. I felt that the extra unit, even the small #1 unit, might contribute to stability as much as the extra 5 MW would degrade it, so left the export at 70 MW. In the most difficult cases, the instability tends to occur between Power Technologies, Inc. Page 5 Bradley Lake and Soldotna, so that adding generation at Bernice probably does improve stability. Once this stability problem is solved, faults that threaten instability between all Kenai generation and Anchorage are no longer a problem (that is, the fixes applied to the Bradley Lake problem also fix any stability problem between Kenai and Anchorage areas). Optimization studies to finalize the compensation should consider various Kenai dispatches, load levels, and export levels. 3.1.2 No Bradley Lake Power Runback The equipment requirements to provide stability at the 120 MW level without a new 230 kV line and without use of the Bradley Lake deflector or unit tripping are: ° 13.8 kV resistor capable of 30 MW for .75 seconds (only .4 or .5 seconds would normally be used). ° Stabilizers on each Bradley Lake unit. ° An SVS with a 30 MVAR dynmiie range at Anchor Point.” ° An SVS with a 15 MVAR dynamic range at Quartz Creek ° Additional switched capacitors are Quartz Creek. o 50% series capacitors in three lines.’ Stability case 116B demonstrates the performance of the above equipment for three- phase fault at the Bradley Lake end of the Bradley Lake Soldotna line. Stabilizers are included on Cooper Lake, Bernice Lake, Bradley Lake, and the SVS at Anchor Point. The Cooper Lake and Bernice Lake stabilizers are later shown to not be essential. The cost of this SVS can be reduced by allowing the SVS control to switch on a capacitor bank (about 15 MVAR) when a power swing is detected, and applying a thyristor controlled reactor with 15 MVAR steady state capability and 25 MVAR short-time overload capability. * About 4 MVAR between Bradley Lake and Fritz Creek, and 6 MVAR between Anchor Point and Kasilof, and between Soldotna and Quartz Creek. Because fault levels are low, it may be possible to avoid bypassing equipment on these units, thus reducing cost. Power Technologies, Inc. Page 6 Stability case 117 has a stabilizer on the Anchor Point SVS only, and shows growing oscillations. Because Bradley Lake power is not run back, no load shedding should be necessary with this scenario. In case 116B the frequency drops .5 Hz over 4 seconds, but only because there is no spinning reserve in the case and because of the energy absorbed by the braking resistor (partially offset by load depression during the fault) and the increased line losses in the Kenai that occur with the Bradley Soldotna line out (later runs show the increased line losses cause most of the frequency decay). There is little room for optimization of the compensation equipment in this scenario (e.g. size, location, etc.). Essentially all of the equipment listed is needed. The only substantial opportunity to reduce cost is in the design of the SVSs to make maximum use of mechanically switched capacitors and short-time rated reactors.* 3.1.3 With Bradley Lake Power Runback If, in the scenario outlined above, the deflector is run in and left in to reduce Bradley Lake power, the compensation required for steady state stability and damping can be reduced. The braking resistor size may also be reduced somewhat because of the contribution of the deflector to first-swing stability. The amount of compensation equipment required would depend on the level of Bradley Lake power runback that is desired. Running back to somewhat less than 60 MW would almost totally eliminate the need for series and shunt compensation because the power through Fritz Creek would be only slightly higher in the post-disturbance period than it is before the disturbance. Running back to an intermediate level, say 90 MW, would require some compensation equipment to be installed, primarily to provide dynamic stability. A relatively small SVS, perhaps as small as +10/-5 MVAR may suffice. Running the deflector in to cut Bradley Lake power back will cause load shedding if spinning reserve is below the amount of runback. In addition, some excess load shedding may occur because of the frequency swings that occur in the first seconds after a disturbance. In case 121A the frequency is down to 58 Hz in 6 seconds with no spinning * A reactor with, for instance, a 15 MVAR continuous rating and a 25 MVAR (or more) temporary rating, can be used where the normal operating point, before and after disturbances, is in the range 0 two 15 MVAR, and higher reactive power need be absorbed only for a second or two following load rejection, or to control backswing overvoltages. Power Technologies, Inc. Page 7 reserve and Bradley Lake power cut to 60 MW and held there. The deflector could be used to bring power back to some intermediate level, say 90 MW to 100 MW in this case because of the series capacitors. This would reduce the load shedding, but would eliminate it only if there is significant spinning reserve. Stability case 121A has just three series capacitors (no SVS). The system is stable in all respects. This case would be dynamically unstable (growing oscillations) without Bradley Lake stabilizers or with improperly tuned stabilizers. 3.1.4 With Bernice & Cooper Off The system may be less stable with Bernice and Cooper units off-line because of the loss of voltage support they provide. However, if exports are high (70 MW or more) these units are likely to be off only when Kenai load is low. Reducing the load also affects stability, and may offset the effect of taking a unit off-line. Cases 140 and 140A were run to examine the impact of Kenai load and Bernice generation level on stability. Case 140 has Bernice #2 operating with Kenai load at 50 MW and Bradley at 120 MW. Anchorage and Fairbanks areas are represented with summer low peak loads and generation.’ Export is 68.2 MW. Case 140A is identical except Bernice #3 is also on and Kenai load is increased to 70 MW. Export is 68.1 MW in this case. The Anchor Point SVS is at -5 MVAR in both cases. The Quartz Creek SVS is at 19.75 MVAR in case 140 and 23.3 MVAR in case 140A. Comparing the cases indicates the condition with Bernice #3 on and heavier load to be only very slightly more stable from both first-swing and damping points of view. However, the difference is so small that it need not be of concern as the system is planned. Though the load level and the number of Bernice units operating may affect stability for some other fault locations more than it does fault and trip of the Bradley to Soldotna line, it is clear that the stability of the Kenai region is primarily a function of the export level and the Bradley Lake power level. Cases 140B can also be compared with case 116B. These two cases are very similar with two exceptions. Case 116B has stabilizers on Bernice and Cooper units, and Tepresents winter peak conditions in the Anchorage and Fairbanks areas. First-swing stability is almost identical, but damping is much better in case 116B. The damping difference is probably due almost wholly to the Bernice and Cooper stabilizers, because a change in load and dispatch in the Anchorage area would not be expected to have a 5 70 MW Kenai load may not be representative of summer conditions, but is used in these cases to provide a comparison rather than an absolution evaluation of summer or winter stability. Power Technologies, Inc. Page 8 significant affect on damping. These cases show the greatest impact of Bernice and Cooper stabilizers of any of the cases done so far in this study, but do not indicate that they are worth the investment they would require. The most important observation from a comparison of cases 116B and 140B is that differences between winter and summer conditions in Anchorage do not affect Kenai stability significantly. 3.2 90 MW AT BRADLEY LAKE Reducing Bradley power level reduces first-swing, dynamic, and steady state stability problems. The deflector can contribute to all three, but increases the risk of load shedding. The following cases explore stability at 90 MW with and without use of the deflector. 3.2.1 Base Case Power Flow The base case power flow has the following conditions: ° Kenai export at 76 MW ° Bradley Lake at 90 MW oO Bernice Lake at 58 MW (units 2, 3 & 4 on) ° Tesoro at 4.5 MW and Cooper at 15 MW ° Lines closed and second University transformer ° 14.4 MVAR capacitor banks at Anchor Point, Soldotna, and Quartz Creek in SVS cases, 3.2.2. No Bradley Lake Power Runback With no Bradley Lake power runback, a braking resistor can provide first-swing stability, but some compensation is required for dynamic stability. The series of cases 123 through 123D explore the options. These cases show that three series capacitors or a single +15/-10 MVAR SVS at Soldotna will do the job. Power Technologies, Inc. Page 9 The three series capacitors are probably less costly than the single SVS. Also, the amount of switched shunt capacitors at Anchor Point, Soldotna, and Quartz Creek can be reduced if the series capacitors are installed (some switched shunt capacitors are required in the SVS case in addition to the shunt capacitors associated with the SVS). Series capacitors are also likely to be more reliable in that they require no operator involvement, no control, and the system is likely to be stable (though marginally so) with any one of the three banks out of service. 3.2.3. With Bradley Lake Power Runback The base case power flow used to examine 90 MW with power runback has no series capacitors or SVSs. It is otherwise identical to the case used for the SVS case discussed in section 4.2 (It has the three 115 kV 14.4 MVAR capacitor banks). Stability cases 124 through 124C show: ° Stable with 30 MW brake and 30 MW runback (124 & 124A) ° Stable with no brake and 50 MW runback (124B) ° First-swing stable for no brake and 30 MW runback, but second swing- unstable for quick deflector pullout (124C) Cases 124 and 124A are different only in that 124 has Bernice and Cooper stabilizers while 124A does not. The additional stabilizers make a measurable difference, but are not at all essential. Cases 124B and 124C indicate that power need only be run back 30 MW to provide first-swing stability, and that the power cannot be ramped back up quickly to prevent load shedding. The power can be ramped back up to some intermediate level, probably 70 or 80 MW without high risk of dynamic or steady state instability, but the rate at which power is raised should be no more than about 5 MW per second. Power Technologies, Inc. Page 10 Case 126 (see section 7.0) is similar to the above cases except Bradley Lake is run back only to 60 MW, and 20 MW of load is dropped in the Kenai area during the fault. The case is stable, though the first-swing is large and damping is light. However, the appearance of light damping is partly due to the ramp up of Bradley Lake power in this tun. Bradley Lake is back to about 83 MW at the end of this 5 second run. This case supersedes case 124B in that it is stable with less runback and otherwise similar or worse conditions. Also, this case indicates loss of load does not affect stability dramatically. Power flow cases can show the steady state limit. A trial case showed that ramping back up to 90 MW does not cause excessively low voltages or push Bernice Lake and Cooper generators dangerously close to maximum reactive limits. However, it is quite possible for the dynamic stability limit to fall below the steady state stability limit. Further simulations are necessary to confirm that the maximum safe power transfer following loss of the Bradley Lake to Soldoma line is 90 MW. Extending case 126 out to 10 seconds should accomplish this. 4.0 WITH 230 KV LINE 4.1120 MW AT BRADLEY LAKE 4.1.1 Base Case Power Flow The 230 kV line was added between Soldotna and University using data from the SEI report. The Soldotna 115-230 kV transformer reactance is about 2% on a 100 MVA base, and seems low. A 35 MVAR reactor was placed on the Soldotna end of the 230 kV line. This reactor provides about 88% compensation for the line. It is necessary to prevent low voltage in the Kenai following trip of the line. Without the reactor, charging current from the line would flow into the Kenai 115 kV system, forcing shunt capacitors to be switched out to keep voltages down. With the 230 kV reactor on, there is some reactive flow into the 230 kV line at Soldotna, so that upon trip of. the line, this reactive power is available to help supply the suddenly higher 115 kV reactive losses as the power that was flowing over the 230 kV lines shifts to the 115 kV line. Power Technologies, Inc. Page 11 The Kenai export is 80 MW in this case. Kenai generation is unchanged. The 115 kV metering point remains just above Dave’s Creek. The export increase from 76 MW to 80 MW is apparently due to lower losses between Soldota and Dave’s Creek, though this seems high. I believe the export metering point is at the Soldoma end of the 230 kV line, but will double check this for the final report. 4.1.2 No Bradley Lake Power Runback On the assumption that the 230 kV line would make a substantial contribution to Bradley Lake stability, the following series of cases was run so determine the maximum Bradley Lake power that could be generated (no change in Kenai export) without additional compensation or runback. Case 127 was run with the 230 kV line and Bradley Lake at 90 MW (see section 6.0) and forms the starting point for the cases with increased Bradley Lake loading. Cases 127A through 127C are similar to 127 except that Kenai generation dispatch is changed to increase Bradley Lake power and decrease Bernice Lake power as shown in the table below. All three are first-swing unstable. Case Bernice Lake (MW) Bradley Lake (MW) #2 #3 #4 127 16 21 21 90 127A 16 0 21 113 127B 0 24 24 100 127¢€ 13 18 18 100 Case 127C was an attempt to improve stability between Bradley Lake and Soldotna by increasing the inertia and strengthening the Soldotna bus. Because in these cases Bradley Lake pulls away from the other plants, this should help. But, it was not enough to do the job. The maximum Bradley Lake schedule with no equipment additions except the 230 kV line is 90 MW or very slightly above 90 MW (but less than 100 MW). No load dropping was represented in these cases. Case 127 may be unstable or marginally stable with load dropping assumed to occur. Power Technologies, Inc. Page 12 Two cases were run in an attempt to increase Bradley Lake power by using a braking resistor to provide first-swing stability. The fault is on the Bradley Lake to Soldotna line. The Kenai export is 80 MW. Bernice Lake #3 (21 MW) is off and Bradley Lake is increased 23 MW to 113 MW (to cover an additional 2 MW of loss). In case 129A, a 30 MW brake is applied for .33 seconds (the best combination in many previous cases), but does not achieve first-swing stability. A longer brake time (.43s) does provide first-swing stability in case 129B, but the large subsequent oscillations lead to loss of synchronism on the third swing. It is clear from these cases that the 230 kV line does not significantly improve stability for fault and trip of the Bradley Lake to Soldotna line. The system can be made first-swing stable, but requires significant additional compensation to be dynamically stable. The amount of compensation required will be somewhat short of that shown to be required if the 230 kV line is not build. The 230 kV line improves Kenai stability significantly, but improves Bradley Lake stability only minimally because it does not eliminate the large impedance between Bradley Lake and Soldoma following tip of the Bradley Lake to Soldoma line. Series capacitors or an SVS can compensate for the length of these lines. 4.1.3 With Bradley Lake Power Runback Just one case (129) was mun to assess the possibility of using the deflector to increase Bradley Lake power output above 90 MW with the 230 kV line in. The case is first-swing unstable, with Bradley Lake pulling out of step with Bernice Lake and Cooper in spite of a 40 MW power reduction by the deflector. A combination of a braking resistor and runback would provide stability for up to 120 MW at Bradley Lake and 80 MW Kenai export. The loop from Bradley Lake to Soldotna is limiting. The 230 kV system improves stability of Bradley Lake somewhat, but does not solve the problem of the long distance from Bradley Lake to Soldotna. As in cases without the 230 kV line, reducing the power with the deflector can solve the problem of the long path from Bradley Lake to Soldoma via Fritz Creek. Without the 230 kV line, Bradley Lake was stable at 120 MW with the braking resistor and runback applied, or just a large runback applied (cases 124 -124C). The 230 kV line will reduce somewhat the size of the braking resistor or the depth of the runback, but will not eliminate it. Power Technologies, Inc. Page 13 4.2 90 MW AT BRADLEY LAKE 4.2.1 No Bradley Lake Power Runback The system is stable with no SVS, no series capacitors, no brake, and no use of the deflector for a Bradley Lake to Soldotna line fault when Bradley Lake is operating at 90 MW (case 127). Note, however, that only one Kenai dispatch was examined to formulate the above conclusion. Some cases should be run for various load and generation configurations to ensure that this conclusion is always true. 4.2.2 With Bradley Lake Power Runback Runback need not be considered for this power level if the 230 kV line is installed, as the system will be stable without it. 4.3 Fault and Trip of the 230 kV Line Case 128 was run to test stability for a three-phase fault on the 230 kV line near Soldotna. It was run with 80 MW export, three Bernice Lake units on at 58 MW otal, Cooper on at 15 MW, and Bradley Lake on at 90 MW. The first swing is marginally stable, and damping is very light. No load was dropped in this case. Because the first- swing is vary marginal, any loss of load would likely make the case unstable. This case shows that the system can remain stable upon loss of the 230 kV line without use of the braking resistor or deflector with export at 80 MW (and somewhat below 80 MW with some loss of load assumed to occur). This would indicate that a brake and/or deflector could be used to make the system stable for the same disturbance at somewhat higher export. Power Technologies, Inc. Page 14 5.0 OTHER FAULT LOCATIONS - LOSS OF LOAD - INADVERTENT BRAKE APPLICATION Several stability cases were run to be sure that fault locations other than the Bradley Lake end of the Bradley Lake to Soldotna line is the worst-case fault location. These cases were run with 90 MW at Bradley Lake, 76 MW Kenai export, no series compensation, no SVSs, no braking resistor, and no us of the deflector. Only Bradley Lake has a stabilizer in these cases. The first three are for 115 kV transmission to Anchorage, the last one is for 230 kV. Case 125 is for a three-phase four cycle fault near Soldotna on the Soldotna to Ski Hill line. This fault weakens the system between Soldoma and Bradley Lake, as well as accelerating all Kenai area generation. The system is easily first-swing stable, and is damped, though the damping is somewhat on the marginal side. Case 125B is for a three-phase four cycle fault on the 115 kV line from Dave’s Creek to Lawing. This fault accelerates Kenai area generation and drops load from the system, thus increasing the power flow up to Anchorage. Because this fault, like any other in the Kenai are, would also cause some other Kenai load to drop from the system, an additional 20 MW of load spread uniformly across the Kenai was dropped. In addition, somewhat arbitrarily, the Dave’s Creek 25 kV load was dropped. The total load dropped is thus 31.1 MW (11.1 MW for Lawing and Dave’s Creek 25 kV, and 20 MW elsewhere). The case is first-swing stable, but is very poorly damped. The higher angle between Kenai generation and Anchorage generation, caused by the loss of load, puts the system very near the dynamic stability limit (with Bradley Lake stabilizers operating -- the system would be dramatically unstable without the Bradley Lake stabilizers). The problem of dynamic instability for disturbances that are not otherwise a threat should be considered further. For example, a case should be run with a more complex load model (i.e. including dynamic models of induction motors) in the Kenai area. If this case shows that the load model presently being used (constant current real part, constant impedance imaginary part) is quite pessimistic, then such cases may be deemed adequate. If damping remains a problem, then additional consideration should be given to stabilizers on Bernice Lake and Cooper units or a modest sized SVS. Case 126 was run primarily to check stability of the Bradley Lake plant with the assumption that the three-phase four cycle fault near Bradley Lake on the Bradley Lake to Soldotna line will drop load in the Kenai area. 20 MW of load is dropped at the instant of line trip (motor contactors open in about 3 cycles, and thus may actually precede line clearing by a cycle). The case is otherwise similar to case 124B (the deflector is used to Power Technologies, Inc. Page 15 run power back to 60 MW). The first-swing is large but stable (slightly better than "marginally stable"), and damping is marginally adequate. Case 136 is a test of stability for a fault at the Soldoma end of the Soldoma - Bradley Lake line with the 230 kV line in and no other compensation added. A fault at this location will accelerate Cooper and Bernice more than will a fault close to Bradley, but will accelerate Bradley lake less. The first-swing is large, but the case is stable. Damping was not checked, but should be the same as for a fault at the Bradley Lake end of the line if the first swing is not significantly larger (a large first swing can initiate oscillations that are too large for the stabilizer to handle). Since the first-swing is quite large, this case could be a problem. However, series capacitors or an SVS would solve the damping problem and would likely be installed to take care of other faults. Inadvertent braking resistor application was investigated in case 138. This case includes no SVSs, and no series capacitors. Though the brake is expected to be applied at 30 MW for .33 seconds, this case was run with the brake held on for .5 seconds, the case is stable, indicating little risk of instability for inadvertent brake application. Occasional testing of the brake is recommended if it is found that it will operate less than about once per year due to disturbances. Stability cases should be run to pick the conditions under which the brake will cause the least disturbance (and risk of loss of customer load). 6.0 SUMMER LOW PEAK CONDITIONS The summer low peak case is similar to the Winter Peak case except that Bernice generation and load is reduced throughout the system. A number of shunt capacitors are removed in the Anchorage area. Because of the heavy export, Kenai shunt compensation is not changed significantly. With these being the only differences, stability is shown to be almost the same as for the Winter Peak. Case 140 shows that the system is stable for fault and trip of the Bradley Lake to Soldotna line with Bradley Lake at 120 MW, export at 68.2 MW, Kenai load at 50 MW. Like similar winter cases, there are series capacitors in three locations and two SVSs. A 30 MW brake is used at Bradley Lake, but the deflector is not used. The results are similar to Winter cases. See previous explanation of cases 140 and 140A in section 3.1.4. Power Technologies, Inc. Page 16 7.0 NO LINE FROM BRADLEY LAKE TO FRITZ CREEK (& No 230 kV Line) Without a line between Bradley Lake and Fritz Creek, the most critical fault location is the Soldotna Ski Hill line. Faults on this line will accelerate Kenai area generation and remove all load served by this line (39 MW at the Winter Peak) from the system. Most of the power that was flowing to this load will transfer to the Quartz Creek - University line, thus contributing to a large power swing as Kenai generation swings ahead to a higher angle to ship over 100 MW from Soldotna to Anchorage. The large increase in line loading between Soldotna and University causes a large increase in reactive losses between Soldotna and University. In addition, the line to Ski Hill is delivering 9.8 MVAR‘ to Soldotna which must be replaced. With Cooper and Bernice Lake generation at maximum reactive output, an additional 38 MVAR is required. Also important is the post-disturbance angle between Bradley Lake and Anchorage which is over 70 degrees. Such a high angle requires that some form of continuous voltage control be provided between Bradley Lake and Anchorage. The system could be made first-swing stable with a braking resistor at Bradley. An SVS at Quartz Creek or Soldoma would provide the large increase in reactive power to maintain steady state stability. Damping would be acceptable, but would be improved by an SVS that is somewhat larger than necessary for steady state stability. Also, because of the high angle, an SVS should be sized to remain below ceiling in the post-disturbance steady state period. Because the fault on the Soldotna to Ski Hill line will remove load from the system (38 MW at Winter Peak), it is reasonable to run the Bradley Lake deflectors in for this disturbance. Running the deflectors in by the amount of load loss would not cause load shedding, but would hold the loading of the lines from Soldoma to University at or close to the predisturbance loading, and thus avoid the need for an SVS,’ or at least limit the size of the SVS to that required for stability. § 115 kV capacitors (14.4 MVAR) were added at Anchor Point to hold voltages on the line to Homer. Reactive flow northward is necessary to offset resistive voltage drop from the southward power flow on the relatively high resistance 115 kV lines. q Trip of the Ski Hill line will remove a 10 MVAR from the Soldoma bus, but this will be more than compensated by the reduced reactive load imposed by the Bradley Lake line when its loading is reduced from 120 MW to 80 MW. Power Technologies, Inc. Page 17 Use of a braking resistor and the deflectors alone (no SVS or series capacitors) was found to be insufficient for stability. The large backswing following the first swing of the three Kenai plant caused excitation to drop on all three plants, so that the "synchronizing power" on the second upward swing was very low, insufficient to maintain synchronism. The backswing voltages are high because of the amount of shunt capacitors on line to support voltage. To rectify this, an SVS was added with 10 MVAR reactive capability to pull voltages down and relieve the need for generator voltage regulators to do so. Stability case 122A shows the performance of a 30 MW braking resistor applied for .33 seconds, the deflector run in 40% over a .4 second period, and a +15/-10 MVAR SVS at Quartz Creek, stabilizers on both Cooper units, Bernice Lake #3, and Bradley Lake, and a three-phase fault on the Soldotna Ski Hill line near Soldotna. Bernice Lake #1 (8 MW) is operating, but does not have a stabilizer. The system is stable in all respects, though it is not well damped. A stabilizer on the SVS would improve damping somewhat. Series capacitors in the Soldotna Quartz Creek line would help stability and reduce the size of the SVS. Quartz Creek is the optimum SVS location, but an SVS at Soldotna (possibly larger) may be satisfactory. The brake and deflectors could be triggered by distance protection looking from Bradley lake toward Soldotna, by acceleration of the Bradley generators, or by direct transfer trip from fault relays at Soldotna. Faults between Quartz Creek and University will separate Kenai and Anchorage areas, and thus are not a stability hazard. Faults between Bradley Lake and Soldotna will isolate the Bradley Lake plant, and thus are not a stability problem. Single pole reclosing should be considered for the Bradley Lake Soldotna line, and the lines between Soldoma and University if transient single-phase faults are expected on these lines. Single pole reclosing would allow the system to ride through transient single phase to ground faults. 8.0 LOSS OF KENAI - ANCHORAGE TIE Trip of any of the lines between Soldotna and Anchorage (not followed by successful reclosing) will isolate the Kenai area with much excess generation if the trip occurs during heavy Kenai export. The resulting overspeed can be damaging to customer loads and turbine-generating equipment if not controlled. Power Technologies, Inc. Page 18 The Bernice combustion turbines have an overspeed trip at 63 Hz, so a frequency excursion above this level could trip one or more of these units. Trip of these units would leave Kenai frequency control in the hands of the Bradley Lake units, which cannot provide adequate speed control when operating under needle-valve control. Though overspeed above 5% does not appear likely for the export levels considered in this study (see following paragraphs), a higher overspeed trip would be highly desirable to minimize risk of CT trip. The 5% overspeed trip is quite conservative, and a higher setting should not measurably increase risk of turbine-generator damage. It is recommended that the manufacturer be consulted regarding a higher setting, perhaps closer to 7 or 8% (there is an “overspeed bolt," a mechanical overspeed trip set at 10% on most CTs which is backup to this electrical overspeed trip circuit). The Bradley Lake deflectors can provide rapid power runback upon loss of the Kenai-Anchorage tie under export conditions. Case 134 shows loss of the Kenai- Anchorage tie under an export of 83.5 MW with the deflectors assumed to be the only means of reducing power, and assumed to be runback by the amount of the export. The deflector is assumed to start the runback .2 seconds after the loss of the tie and have a .05 second actuator time constant. At .2 seconds the Kenai frequency is up to 60.7 Hz and is rising at the rate of 3 Hz/s. The conditions under which runback should be triggered needs further consideration, but the assumptions used for case 134 are probably quite practical and close to those that will be implemented in the Bradley Lake governor programmable controller. The Bernice Lake combustion turbines can be tripped on reverse power if Bradley Lake does not ramp back sufficiently to allow the combustion turbines to settle at partial output. This will require coordination of the droop characteristics of the two plants, and, possibly, consideration of the dynamic response of the respective governor systems. Properly set reverse power relays at Bernice Lake (i.e. not overly sensitive) will also be essential to keeping the Bernice Lake units on-line following loss of the Kenai - Anchorage tie. In case 134 the voltages go quite high between .5 and 1.5 seconds after loss of the Kenai-Anchorage tie. The high voltage is due primarily to the loss of the export load, but also partly due to reaction of the Bradley Lake stabilizer to the overspeed. Loss of line loading due to loss of export is the biggest problem. The reactive current from capacitors added to support the line reactive losses flows to the generators, and thereby causes high voltage. The SVS at Anchor Point is at +2.3 MVAR before the separation, and with a -5 Power Technologies, Inc. Page 19 MVAR lower limit, absorbs little of the excessive capacitor current. In fact, it can be seen that the angle between Bradley and Bernice generation is increasing toward the end of the tun. This is because the excitation at Bernice and Cooper is being pushed down by voltage regulators trying to hold down voltage (the voltages are all 3 to 5% high in the final seconds of the run). The low excitation requires a higher generator angle to produce power, and will lead ultimately to loss of synchronism in case 134. It is essential that the following loss of the Kenai - Anchorage tie. In case 134 this could be achieved by increasing the underexcited range of the SVS or by tripping shunt capacitor banks with overvoltage relays (time delay in these relays would be critical). Where possible, the shunt capacitors should be controlled by the SVS controller. The Bradley Lake stabilizer modeled in this case is set to respond to accelerating power. Because accelerating power remains high until the overspeed is halted, the stabilizer boosts Bradley excitation, compounding the overvoltage problem. The Bradley stabilizer can be switched to operate from electrical power at the generator terminals to reduce its response to the overspeed without significantly affecting performance under other conditions. This will be done in later cases. If an SVS is included in the final recommended compensation package, it will be sized to control separation overvoltages or will be supplemented by shunt capacitor controls to do so. Series capacitors inherently contribute less to overvoltages than shunt capacitors. They are series elements in the lines, and generate less reactive power when line power drops. 9.0 RELIABILITY DIFFERENCES BETWEEN 115 Kv AND 230 Ky ALTERNATIVES For disturbances in the Kenai area, the alternatives with and without the new 230 kV line are similar. Both alternatives depend on equipment such as stabilizers, braking resistors, deflectors, or series capacitors and SVSs. For faults between the Kenai and Anchorage areas on the lines between Soldotna and the Anchorage area, the 115 kV alternative is at a disadvantage. With a 230 kV line, fault and trip of the 115 kV line is not a problem. Fault and trip of the 230 kV line is a threat at higher export levels, but application of the Bradley Lake brake and/or deflector can solve this problem. Power Technologies, Inc. Page 20 If the 115 kV lines form the only tie between the Kenai and Anchorage areas, reliability can be improved by applying single-pole or three-pole reclosing on the 115 kV lines. Reclosing can be used to maintain stability for transient faults. Reclosing will be successful at low transfers but may require use of the Bradley Lake brake to be successful at higher transfers (e.g. in the vicinity of 80 MW). The prospects for use of reclosing on the 115 kV lines between Kenai and Anchorage will be investigated in the optimization phase of the study (Phase II). Power Technologies, Inc. APPENDIX I FIRST-SWING, STEADY STATE, DYNAMIC STABILITY Power Technologies, Inc. APPENDIX I FIRST-SWING, STEADY STATE, DYNAMIC STABILITY First-Swing Stability First-swing stability or "transient stability" refers to the first second or so after fault and trip of a line. Faults depress generator electrical output, forcing power delivered by the turbine to be stored as kinetic energy in the turbine and generator rotors. With the exception of the deflector at Bradley Lake (which can be "triggered to run power back quickly), governors do not change turbine power significantly in the critical first half second after a fault, so the energy storage is quite large. The rotors accelerate as the energy is stored in them, making the generator(s) near the fault "pull ahead" of other system generators. A system is first-swing stable if these generators continue running faster than other generators. The power out of a generator (once the fault is removed) rises as a generator pulls ahead of other system generators. This rise in power will slow the accelerated generator and bring it back to synchronous speed if the generator is strongly tied to other generators through short lines. In the case of Bradley Lake, the lines are long so there is very little natural increase in generator power after the fault is removed. The power out of the generator can be increased by shortening the lines with series capacitors which offset the line reactance, by holding voltage up along the line with an SVS, raising generator voltage through increased excitation voltage, or by applying a braking resistor near the generator. The braking resistor removes the kinetic energy by taking a large amount of power for a fraction of a second. Running in the deflector reduced the kinetic energy stored by reducing turbine power. If generator speed is restored to the average speed of all other generators in the system before it "pulls out of step,” it will be first-swing stable. Dynamic Stability The electromechanical system formed by turbine-generators and the electrical network depends heavily on control systems. The most important controls are the governors and voltage regulators. When a long transmission system is heavily loaded, and the gain of excitation systems is increased to improve first-swing stability and provide good control of voltage, systems typically become oscillatory. The power oscillations, if sustained, cause wear and tear on governing systems and voltage fluctuations that bother customers. If the oscillations grow, the usual case, the system becomes unstable and Power Technologies, Inc. separates into islands with likely collapse or at least heavy load shedding in generation deficient islands. Circuitry must be added to ensure such oscillations do not occur, or are quickly damped when initiated by a fault and/or line trip. This is done by adding damping at the natural system frequency (usually around 1 Hz). The least costly and most effective stabilizing circuitry is the "PSS" or power system stabilizer applied to the excitation system of generators that are most heavily involved in the oscillations. The PSS modulates generator excitation and in doing so provides a sinusoidal component of power that leads the natural power swings, thus providing damping. Series capacitors help by strengthening the network. SVSs help by combating the natural voltage oscillations that accompany the power oscillations. In systems where large oscillations are poorly damped or will build up while smaller ones are damped, a temporary power reduction can bring the oscillations under control. The deflector on the Bradley Lake turbine can do this. Steady State Stability A stable system must not only survive the first swing and be subsequently damped, it must also be able stable when voltage regulators and governors have settled out at new operating points. A system is stable when small changes in load or power do not case the "voltage angle" across the system to increase to the point that power transfer necessary to satisfy governor settings is not achieved. Additionally, the steady state is affected by the changes in system loads that occur in the minutes after a disturbance. Motors dropped by the fault will be returned to service, and LTCs will restore voltage on distribution loads when the bulk system voltage is low. Loads where voltage remains low will tend to return to their initial power level as thermostats and manual controls. adjust to the lower voltage. Also, generation dispatches may be changed after a disturbance. For a system to be declared steady state stable, it must be stable throughout the 5 to 10 minute period after a disturbance when these changes are occurring. Power Technologies, Inc.

APPENDIX III BRAKING RESISTORS Power Technologies, Inc. APPENDIX III BRAKING RESISTORS Braking Resistor Consi ion Application considerations include: ° Inadvertent energization or test energizations should not cause instability or intolerable voltage excursions. ° The circuit breaker should be rated well above nominal system voltage since it must continuously operate with line potential on one side and ground potential (through the resistor) on the other. ° A test energization should be run at the end of any 6 month period in which it has not been tested and has not operated in response to a disturbance. ° Triggering options include: - undervoltage relays (e.g. any two or more phases to detect multi-phase faults) - relays that initiate clearing of lines in the local substation - signals from remote relays via carrier - back contacts on line circuit breakers - rotor acceleration detector (rotor speed calculated from generator terminal voltage, current, and frequency) The triggering can consist of a combination of the above. Power Technologies, Inc. ° Braking resistors do not necessarily have to be located at the generating plant where the angular acceleration is the greatest. A remote location may require a somewhat larger resistor, but control may be simplified and reliability improved. A remote location may be optimum if the resistor is to serve more than one plant. Power Technologies, Inc. APPENDIX IV SERIES CAPACITORS Power Technologies, Inc. APPENDIX IV SERIES CAPACITORS A series capacitor installation will usually include the main components shown in the following sketch. Sometimes the capacitors are broken down into several "modules" to improve protection. If the amount of series compensation needs to be changed from time to time, each module can have its own bypassing equipment and bypass switch.* 115 kV capacitors in the Kenai region would likely consist of a single module as shown in the sketch. CB to clear gap Gaps to protect Mov This equipment can he \ to protect capacitors woided if fault level is low. Overcurrent protection Figure 1 -- Typical Series Capacitor If fault levels are no more than about 3 times the maximum continuous current the capacitors will be called on to carry, the bypassing equipment can be limited to the switches necessary to take the capacitors out of service for maintenance. A preliminary For instance, if the Bradley Lake to Soldotna line and lines between Bradley Lake and Soldotna via Fritz Creek were to both be series compensated, losses might be reduced by varying the level of compensation in steps. All capacitors would be switched in when a fault is detected. Power Technologies, Inc. fault study indicates that without the 230 kV line, all the series capacitor banks considered it this study can probably be most economically constructed without the usual bypassing equipment.’ When series compensation at levels exceeding about 40% are considered, it is usually necessary to locate the capacitors near the center of the line or split them into two banks, one at each end of the line. This is done to limit the voltage stress on line and station equipment caused by the voltage rise caused by reactive power flow through the bank. However, at lower voltages (230 kV and below), the reactive flow may be low enough, or the line voltage withstand capability high enough, to allow 50% or more at one end. i Subsynchronous Oscillations The series capacitors between Soldoma and Quartz Creek may pose some risk of subsynchronous oscillation for the Soltdotma generator. Such oscillations could occur if a disturbance were to leave the Soldoma CT alone on the 115 kV lines from Soldotna to University. If the series capacitors between Soldoma and Quartz are resonant with the line impedance at a frequency that translates across the air-gap of the generator to a torsional frequency that is at the natural frequency of the turbine-generator shaft or the turbine- compressor shaft, electromechanical oscillations involving the two systems could build up, ultimately failing the shaft. This possibility should be checked before installing the Soldotna Quartz series capacitors. An SSO relay on the Soldotna generator may be sufficient protection against SSO damage. SSO is also a remote possibility for the Bradley Lake machines, and this too should be checked. However, it is quite unlikely that electrical and shaft torsional frequencies will coincide. The high system impedance makes the electrical resonant point very high. This high electrical resonant point translates to a low shaft torsional frequency which is usually quite far from the normally high shaft natural frequency of the shaft between a low inertia turbine and high inertia generator. ° Standard capacitors can withstand 2.6 times rated current for 15 cycles. Higher currents can be withstood for shorter periods of time. Even if higher fault currents capability is required, it may be less costly to install higher rated capacitors than to install the bypass protection. Power Technologies, Inc. APPENDIX V GLOSSARY Power Technologies, Inc. APPENDIX V GLOSSARY ili To be fully stable the system must meet all of the following criteria for all credible "first contingency" disturbances: First-swing The system must survive the angular excursion following energy storage in machine inertial due to fault or a sudden drop in power transfer as might be caused by line trip. Dynamic Oscillations initiated by a fault or line trip must damp out within 10 to 15 seconds, and must not arise spontaneously some minutes after a disturbance. Steady State The system must remain in synchronism not only in the first seconds following a disturbance, but in the 5 to 10 minutes after a disturbance and before operators can take action to reduce excessive transfers. Voltage The system must not experience voltage collapse immediately after a disturbance or in the 5 to 10 minutes after a disturbance and before operators can take corrective action to restore voltage and line loadings. Power Technologies, Inc. APPENDIX VI STABILIZERS Power Technologies, Inc. APPENDIX VI STABILIZERS Bradley Lake Power System Stabilizers (PSS) on the Bradley Lake voltage regulators are essential. All early stability cases that were first-swing stable were dynamically unstable until stabilizers were added at Bradley Lake. In the optimization stage, the final recommended system will be tested with and without the stabilizers, and with one stabilizer out of service to confirm the need for stabilizers and to determine if transfer constraints will be necessary when one stabilizer is out of service. The stabilizer applied to Bradley Lake has the form and settings shown in the sketch below. This is the most modern type of stabilizer in that it is a free-standing unit that calculates accelerating power from terminal voltage and current, and thus avoids the problems of developing a clean shaft speed signal. 2H 201+. Ss)(1+. 15") Tap nent Selection -—————> (1+ 2)€1+.8S9) Table P * Accelerating power derived From generator power and speed as calculated from current & voltage Power Technologies, Inc. V. m_Stabili The SVSs contribute to damping by providing fast voltage control. Since much of the damping problem comes from the changes in system voltage seen by generator voltage regulators, the action of the SVS to reduce voltage excursions improves stability by reducing the magnitude of the voltage variations at the generators. However their contribution can be increased further if they are used to modulate the system voltage in phase with sending end generator speed. Since the Bradley Lake sinusoidal speed variations lead the corresponding sinusoidal power variations by 90 degrees, a stabilizer i that takes through power as input, applies a 90 degree lead circuit, and feeds the result to the SVS voltage regulator will improve damping. The stabilizer used in the study has the following form and time constants shown in the sketch below.

APPENDIX VII PROTECTION NOTES Because the system is stability limited and will depend heavily on devices such as SVS and braking resistor for stability, there are likely to be occasional cases of instability. Instability will cause line fault protection relays near the “electrical center" of the weakened system to operate. If such relays are allowed to trip upon an out-of-step condition, load may be unnecessarily removed from the system or exposed to very high voltage or high frequency. Circuit breakers, insulators, and substation equipment can also be damaged by the inherent response of relays to out-of-step conditions. The impact of an out-of-step condition can be minimized by installing relays that will trip circuit breakers to isolate the out-of-step portions of the system at specific locations. For instance, trip of the Soldoma-Bradley line would be preferable to trip between Soldoma and Anchorage (for loss of the Bradley-Fritz Creek line), and trip between Bradley and Fritz Creek would be preferable to trip between Fritz Creek and Soldotna (for loss of the Bradley-Soldoma line). The lines which would trip upon out-of-step can be identified from stability studies. Stability work to design the system may reveal the electrical center for a range of disturbances. If such studies do not provide a complete picture, additional unstable cases can be run. The selection of the best locations for out-of-step tripping, and the timing of the trip, can often be identified from these same cases, though additional simulations of the post-separation period may be required to confirm desirable system response to the separation (i.e. in terms of voltage and frequency excursions). Power Technologies, Inc. APPENDIX VIII TURBINE DEFLECTOR CONSIDERATIONS Power Technologies, Inc. APPENDIX VIII TURBINE DEFLECTOR CONSIDERATIONS Turbine Deflector The turbine deflector offers stability benefits quite similar to a braking resistor. The deflector can be triggered in essentially the same way as a braking resistor. The difference is that the deflector "cuts-in" over a period of time rather than being suddenly fully engaged like a braking resistor. However, to the extent that the deflector can reduce power applied to the generator within about the first .5 second after a disturbance, it will improve stability. It can thus reduce investment in the braking resistor or other equipment such as SVSs that are needed solely to improve first swing stability.

These included: ° Bradley maximum operating power level ° Various levels of power runback following disturbances ° Various combinations of SVS and series capacitors ° Use of a braking resistor at Bradley Lake ° Use of stabilizers for dynamic stability Phase I work was based largely on 75 MW export with intermediate to high Kenai load levels, and generation on-line at Bernice and Cooper. The Phase I studies showed that it would be feasible to provide stability without the installation of a 230 kV line from Soldotna to University. Phase II of the Railbelt Stability Study was originally intended to select and optimize one transmission scheme to meet Bradley Lake power transmission objectives. However, as completed, it provides several alternatives addressing different Bradley Lake power limitations and Kenai export levels. Only one (combination of one SVS and three series capacitors) has been tested for a range of operating conditions sufficient to support the subsequent analysis necessary to prepare equipment specifications. Power Technologies, Inc. EXECUTIVE SUMMARY The several alternatives examined in Phase II are summarized in the following paragraphs. One alternative that was considered in Phase I but not examined further in Phase II is also included to complete the range of alternatives that are available. ° ; a _ - ration Bradley Lake. The equipment consists of braking resistors (with associated communications and controls) and stabilizers at Bradley Lake. The braking resistors (two 25 MW units) are complemented by runback to 60 MW upon loss of the Bradley to Soldotna line to provide stability. Other disturbances will not require runback but may require braking. Kenai export limits have not been fully defined for this alternative, but the cases that have been run indicate export is limited only by Kenai load and losses when Bernice and Cooper generators are off (i.e. just over 40 MW). In Phase I this alternative was found to be stable at 76 MW export with Bernice and Cooper providing the additional power for export. Higher exports may be possible under some conditions. This alternative can be extended to handle somewhat higher Bradley Lake power levels, but would require correspondingly greater runback. This alternative does not address heavy Kenai import conditions under which voltage control is a known problem. ° Equipment additions to allow 120 MW operation at Bradley. This alternative was studied most thoroughly in Phase II. The investment is limited by running Bradley back to 90 MW immediately following loss of the Bradley to Soldotna line. The equipment required includes the two braking resistors and stabilizers at Bradley, one SVS at Soldotna and three series capacitors. It has been tested at maximum export when Bernice and Cooper are off and Kenai load is low (40 MW). It was also tested and found to be stable at 90 MW export with Bernice and Cooper units on, but such operation is very close to stability limits and the alternative was not designed for such operation on a normal basis (i.e. though the system may be stable at this export under ideal conditions, reliability will be lower when it is operated at this export). nN Power Technologies, Inc. Use _ of two SVSs_ rather than one SVS and three series capacitors. This alternative is otherwise similar to the one just described. Two SVS will be more costly than one SVS and three series capacitors. There are also technical advantages and disadvantages, but two SVS will offer about the same capability for Bradley Lake power generation and Kenai export. Two SVS and three series capacitors. This alternative, explored only in Phase I, requires higher investment but does not require Bradley Lake power runback. Though it was not pursued further in Phase II, it bears mention here to complete the array of alternatives. Like all other options, it requires braking resistors and stabilizers at Bradley. This alternative requires upgrading of the 115 kV line from Soldotna to Diamond Ridge to carry the higher power following loss of the Bradley-Soldotna line. New transmission line from the Anchorage area to the Kenai area. A new line from the University substation to the Soldotna substation was considered. Though a very expensive alternative, such a line can eliminate one series _ capacitor and the SVS if rmunback from 120 MW to 90 MW is retained. If Bradley is to be held at 120 MW following loss of the 230 kV line, a small SVS is required at Soldotna. This SVS is also required if the level of dynamic stability performance and margin provided by the 115 kV alternatives is to be achieved. The most attractive feature of this alternative is a reduction in the number of incidents that will separate the Kenai area from the Anchorage area. The compensation package consisting of one SVS and three series capacitors was most thoroughly studied in Phase II. It requires: ° Three series capacitors, 50% each in the lines from Bradley to Fritz Creek, Anchor Point to Kasilof, and Soldotna to Quartz. One SVS +30/-25 MVAR at Soldoma with stabilizer and with control over the existing Soldotma mechanically switched capacitors. Two 25 MW braking resistors with sensitive triggering and a controller to remove them based on Bradley rotor speed. Power reduction to 90 MW by the deflector for loss of the Bradley to Soldotna line. Power Technologies, Inc. ° Power System Stabilizer on each Bradley Lake machine exciter/voltage regulator. ° Bradley automatic voltage regulator line/transformer drop compensation with slow response (optional). The SVS size requirement is based on a number of considerations including first-swing stability, damping, steady state stability, backswing overvoltages, and voltage control during and following islanding. The casework in Phase II makes extensive use of detailed Kenai load models. The model includes large and small motor models .and includes the loss of motor load that occurs during faults. The load model is discussed in some detail in Appendix I. The following sections focus on major considerations in selecting the size and location of compensation and control equipment, and on the various equipment and operating options that can be used to solve the Bradley Lake stability limitations. 115 KV UPGRADE The goal of the Phase II work was to select the best 115 kV transmission upgrade alternative from among those considered in Phase II and test it for a wide range of disturbances and add or modify the recommendations as necessary to provide an optimum system. The alternative consisting of one SVS and three series capacitors was both the least costly and the best performing of the alternatives examined in Phase II, and was selected for further study. The cases discussed in the remainder of this section address a number of aspects of the combination SVS - Series capacitor alternative: ° stability for various 69 and 115 kV faults. ° response to other disturbances ° control of voltage during and following stability swings and separation from Anchorage. ° ability to handle higher export or reduced Bradley runback. Power Technologies, Inc. ‘ ’ In addition, a number of other planning and operating options and considerations are discussed. Because construction of a second Kenai to Anchorage line would require much of the same equipment as is required without a new line, much of the discussion in the following subsections regarding equipment characteristics and selection apply also to that alternative. 69 kV Faults A number of 69 kV faults were examined. In all cases the critical clearing time for three-phase faults is between 6 and 9 cycles. Fault clearing times, including relay and breaker times, must be under the critical clearing time at the source (115 kV) end of radial 69 kV lines, and at both ends of looped lines (e.g. the Soldotna-Quartz 69 kV line). The following table summarizes the results of stability cases 182 though 192. FAULT Stable at: . Unstable at: Cases Soldotma area 6 7 184, 185 Diamond Ridge 7 9 187, 188 Bernice 7 9 191, 192 Lawing 8 9 189, 190, 190A Dave’s Creek 25 kV 20 -- 186 The above clearing times were determined with the braking resistor assumed not to respond to these faults. The braking resistor can make the system stable for 69 kV faults up to several cycles above the critical clearing time without brake use. The voltages at Bradley were recorded for each of these faults, and are below 70% for all cases except the 25 kV fault (which is stable without fast clearing or use of the brake). Hence application of the brake for most close-in 69 kV faults is feasible. Hence where the existing clearing time is not too much above the critical clearing time, the brake may eliminate the need for communications based protection. On radial lines, presumably close-in faults can be cleared within 6 to 8 cycles by zone 1 distance protection. On looped lines, mid-line faults should be cleared promptly at both ends without carrier, and line-end faults will be cleared quickly at the near end and in second zone time at the far end. Power Technologies, Inc. ‘ Only two cases have been run to assess use of the brake for 69 kV faults. The first is case 201 which simulates a three-phase fault adjacent to the Soldoma 69 kV bus on the line from Soldotna to Quartz Creek. The Soldotna end is assumed to be cleared at 6 cycles (zone 1 distance protection) the Quartz Creek end is assumed to be cleared in 24 cycles (zone 2 distance protection). The case is unstable. However, this is probably the worst 69 kV fault in that it removes a section of 69 kV line that parallels the 115 kV tie to Anchorage, and the fault depresses transfer to Anchorage significantly both during the first 6 cycles and during the additional 18 cycle line-end fault period in that both faults are directly off the 115 kV path off the line to Anchorage. This case should not discourage a search for locations where communications might be avoided by depending on the brake. The second case demonstrating use of the brake for 69 kV faults is case 212. This i case examines reclosing on the 115 kV line from Dave’s Creek to Lawing for downstream 69 kV faults. Since the fault clearing time is known only to be between 8 and 10 cycles, a 10 cycle clearing time was used. Because the 10 cycle fault is beyond the critical switching time (see above table and cases 189, 190 and 190A), the braking resistor is used. Reclosing dead times are 18 cycles, 4 seconds, and 20 seconds.. Because faults separated by 4 seconds or more are essentially separate events from a stability standpoint, if stability is achieved for one, all will be stable. However, the 18 cycle dead time for the first reclose places the first unsuccessful reclosing within the "swing period" of the initial fault, making it necessary to consider the two in the same simulation. In case 212 the brake circuit breaker is assumed to close at the instant of fault clearing (this is a conservative assumption, the brake should engage well before the fault is cleared). The brake is removed about .2 seconds later, about .1 second before reclosing again energizes the fault. The brake is not needed for the second fault application because the second fault occurs during the early part of the Bradley angular backswing, and thus only serves to reduce the extent of the backswing. If the reclosing delay were greater, on the order of .7 seconds or more (i.e. just ahead of or around the peak of the "second swing"), the braking resistor would have to be applied to maintain stability. The second brake application would likely be longer than the first (about .3 seconds) if it occurs near the peak of the second swing. Subsequent brake applications for the 4 second and 20 second reclose attempts would each require about .2 seconds of brake time. The total brake time for the four faults would be about .9 seconds, somewhat greater than the .7 seconds selected based on other disturbances. Since the brake will be triggered by most severe 69 kV multi-phase faults (whether essential for stability or not), it must be capable of handling the reclosing that can occur. Also, in order for the brake to be applied several times in rapid succession, its circuit breaker must be able to provide the required sequence of operations. A magnetic type circuit breaker (e.g. GE Magnablast) is capable of rapid close-open operation, but must "recharge" after several close-open operations. This recharge limitation may be less Power Technologies, Inc. significant with a vacuum breaker. Close-open capability of the breakers intended to be used on the braking resistors should be checked to ensure that it will match the fastest 69 kV reclose pattern. The 69 kV clearing times and fault locations that can be accommodated without transfer trip or directional comparison protection (i.e. systems requiring line carrier) by a 40 MW brake must be determined in further exploratory stability cases. Also required for this option is a check of the effects of 69 kV phase-to-phase faults on stability and on the voltage at Bradley Lake. If the brake must be applied for unbalanced 69 kV faults, then the voltage relay logic must be arranged to trigger the brake for such faults (this should not be a problem since the brake must be triggered for unbalanced 115 kV faults also. 115 kV Faults A number of 115 kV faults were examined in addition to a fault on the line from Bradley to Soldotna. Those examined were: ° Fault at Bradley, trip Bradley - Fritz Creek -- unstable without brake, stable with brake (cases 174 & 175). ° Fault at Soldoma, trip Soldotna - Ski Hill -- unstable without brake, stable with brake (cases 176 & 177). ° Fault at Dave’s Creek, trip Dave’s Creek - Lawing -- stable without brake (case 178). These cases show that 115 kV faults in general are a threat to stability, but can be overcome by use of the brake. These cases emphasize the need for brake triggering that is sensitive to all area faults. These faults cause very low voltage at the Bradley 115 kV bus and are thus easily observed from Bradley. Undervoltage relays thus can be used for brake triggering. It is clear that the Bradley brake should be triggered for multi-phase faults. However, a decision must be made as to whether the brake should be triggered for single-phase faults. Single-phase faults on the Bradley to Soldoma line must trigger the brake, but this is easily done from line relays at Bradley. If the brake is to be triggered by ground faults remote from Bradley, the triggering must be based on a one-out-of-three operation of three single-phase voltage relays. There is also the question of Bradley operating level. At Power Technologies, Inc. some low plant output level, the brake will be needed only for faults on the line from Bradley to Soldotna. At low output the brake will not be needed if two units are operating. With one unit operating the brake may be needed when it is near full output. Other Disturbances Three stability cases were run for two miscellaneous disturbances. One is inadvertent braking resistor application, and the other is nuisance trip of a Bradley generating unit under full output. Case 179 is for inadvertent 40 MW brake application at low export. In this case the Bradley angle is low compared to the Anchorage area, so the plant is most susceptible to a disturbance that would slow it and thus take it out of step in a lagging direction (faults accelerate the plant and in an unstable case cause it to pull ahead of the remainder of the system). The brake slows the plant, and thus is a potential threat primarily when the plant angle is initially low. The case shows that the brake is very unlikely to cause instability under any credible operating condition. In fact, the Bradley angle is "turning around" even before the brake is removed at .7 seconds, indicating that the plant is probably stable even if the brake is not removed. If the brake thermal rating is .75 seconds, backup protection would remove the brake within .75 seconds. Case 213 is for inadvertent application of a 50 MW brake under heavy import conditions with one Bradley Lake unit operating in the Kenai. The Kenai load is 75 MW, the Bradley unit is producing 20 MW, and import is 43 MW. The brake is applied for .7 seconds. The case is stable. However, it does show large voltage excursions. Some voltages drop below 50%, and backswing overvoltages reach 120%. The Kenai frequency swings to a high of 60.75 Hz and a low of 59.2 Hz (above the 59 Hz underfrequency relay setpoints). Though the frequency swings are large, and the voltages violate criteria, inadvertent brake application is unlikely to occur because: ° the brake should be disabled during import conditions (and low export conditions). oO if a local (Bradley) control failure occurs, it should only affect one of the two brakes (i.e. 25 MW instead of 50 MW). ° if the braking resistors are energize erroneously by local voltage relays or via carrier from relays on the Kenai-Anchorage lines, it should be removed quickly Power Technologies, Inc. (about .2 seconds) by the same control that will remove it when it is properly applied. Based on the above, inadvertent application of the braking resistors to the extent represented in case 213 is very unlikely to occur, and is thus suggested to not be a problem. Case 180 is for trip of one of two Bradley Lake generating units when the plant is operating at 120 MW. It shows no stability threat or other potential problems. Kenai-Anchorage 115 kV Reclosing Cases 169 though 173 and 202 and 203 address the question of reclosing on 115 kV lines north of Soldotna. Reclosing on the line from Soldotma to Quartz Creek and the line north of Dave’s Creek was examined. The Soldoma to Quartz Creek line has the benefit of the underlying 69 kV line, though this advantage is minimal because of the high impedance of the line and associated transformers (also, the results are slightly conservative because the Quartz Creek transformer was not replaced with the Bernice Unit before cases 169 through 173 were Tun). Faults further north affect the Kenai area load less, and thus would be expected to be somewhat more stable than those examined below. The cases are summarized in the following table. Case 169 64.3 MW export, Bradley at 120 MW, Bernice & Cooper off, 4 cycle single- phase fault at Soldotna, three-pole reclosing, 15 cycle dead time, no brake, no tunback, no load drop. Unstable. Case 170 Same as 169 except brake applied. Stable. Case 172' Same as 169 except single-pole reclosing with 25 cycle dead time. Stable. ‘Case 171 is similar except it represents 15 cycle dead time and was, of course, stable. Power Technologies, Inc. Case 173 Same as 169 except 41.8 MW export, Bradley at 90 MW. Stable. Case 202 64.3 MW export, Bradley at 120 MW, Bernice & Cooper off, 4 cycle single- phase fault at Dave’s Creek, single-pole reclosing on Dave’s Creek - University line, dead time 25 cycles, no brake, no runback, no load drop. Unstable. Case 203 Same as 202 except 15 cycle dead time. Stable. These cases show that three-pole reclosing on the Soldotna to Quartz Creek line is feasible at low export levels (below about 50 MW) without runback or brake operation at Bradley. At higher export levels the Bradley brake can be used to make the system stable. Runback may also provide stability but was not examined. The brake would be more effective and is the method of choice since it represents less risk of load shedding. Single-pole reclosing is stable for dead times up to and including 25 cycles on the Soldoma to Quartz Creek line. Case 172 appears quite stable thus indicating that an even longer dead time could likely be used. Cases 202 and 203 bracket the allowable dead time for single-pole reclosing between Dave’s Creek and University. The limit is in the vicinity of 20 cycles. The Bradley brake could be used to extend the allowable dead time for this fault if communications is available to ensure that the brake will be triggered. The single-phase faults and the single-pole-open transfer impedances used in the above cases are based on very rough assumptions of the zero sequence impedances at Soldotna, Quartz, and Dave’s Creek, and thus the above results must be considered to be approximate. However, since even the 25 cycle dead time cases are quite stable, the error in zero sequence impedance would have to be quite large to invalidate the above conclusions. Load dropping was not simulated in these cases. Load dropping would make the cases less stable. However, single phase faults north of Soldoma should not cause significant loss of load, and thus would only have a secondary effect on the results. 10 Power Technologies, Inc. Backswing Overvoltages Backswing overvoltages are always a problem when measures such as SVSs, series capacitors, high performance excitation systems, braking resistors, and deflectors are used to provide first-swing stability. The voltages go high as the angle across the system approaches zero degrees during the back swing. At this instant the power flow across the system is very low so that line and transformer reactive losses approach zero. Reactive power from capacitors and lines must flow to generators, and thus causes a voltage rise during this short time period. The overvoltage is compounded by the high flux in generators that remains from the first swing, or is pushed up by stabilizers attempting to provide damping. Loss of load during the fault also compounds the overvoltage problem. The backswing overvoltages in the Kenai are most severe when Bradley Lake is the only generation operating (case 161) and area load is low (40 MW). A number of 115 kV voltages exceed 110% for about .5s. Anchor Point and Fritz Creek voltages peak just over 118% (Fritz Creek voltage is not plotted), while Soldotna and Quartz Creek voltages peak at about 116%. When Bernice and Cooper generators are on-line, they absorb reactive power during the backswing, measurably reducing the backswing overvoltages (case 163). With one Cooper and one Bernice unit operating (and Kenai load at 60 MW), the backswing overvoltages are somewhat lower, with the highest 115 kV load bus reaching 117%, and others reaching about 113%. Changing the reactive dispatch among the Bernice and Cooper plants and the Soldotna SVS so that the pre-disturbance plant reactive loadings are lower the SVS output is higher pulls the voltages down 2 to 3% (compare cases 163 and 164). The cases discussed in the above paragraph are all based on an SVS at Soldotna with a +20/-15 MWVAR dynamic range. Additionally, there is a 30 MVAR capacitor bank operating at Soldoma and a 7.2 MVAR bank operating at Quartz Creek. The -15 MVAR SVS lower limit does not allow the SVS to absorb all reactive power from these capacitor banks. The remaining 22.2 MVAR is a significant contributor to the backswing overvoltages. Case 162 shows that increasing the SVS lower limit by 10 MVAR reduces the overvoltages by 3 to 4 percent. Case 162A shows that reducing the SVS lower limit by yet another 10 MVAR provides an additional 3 to 4% reduction. However, note that 2 The capacitor bank at Quartz Creek was added to improve the voltage profile between Soldoma and University. It agreed in the Phase II preliminary report meeting in Anchorage on March 2 to remove this capacitor bank and adjust the SVS size or Soldoma capacitors to compensate for it Cases above number 205 do not represent this capacitor bank. The drop in voltage is partly offset by raising the 138-115 kV University transformer tap 2.5% and by increased SVS output at Soldoma. 11 Power Technologies, Inc. the drop in overvoltages is most pronounced at and near Soldotna, with voltages closer to Bradley, such as Fritz Creek and Diamond Ridge less improved. Overvoltages will be less severe for less severe faults. The cases discussed above all focus on a three-phase fault near Bradley. Case 165 is similar in all respects to case 161 except that it represents a phase to phase fault near Bradley. The backswing overvoltages are all 112% or less at all buses except Bradley Lake. Moving a three-phase fault some distance from Bradley, say 5 to 10 miles, would have a similar effect. Only three-phase faults near Bradley will cause the backswing overvoltages exhibited in cases 161-164. The backswing overvoltages are aggravated by the drop in generator power caused by use of the deflector. Delaying cut-in of the deflector will require a larger braking resistor, but will reduce backswing overvoltages. The Bradley stabilizers also aggravate backswing overvoltages. Stabilizers "see" the acceleration of the plant during and immediately after the fault as part of an oscillation, and increase excitation beyond the increase caused by the fault and post-fault power swing, thus driving machine flux up so high that the voltage regulator cannot pull it down during the backswing. Case 205 was run to explore these two effects (it also does not have new shunt capacitors at Quartz Creek). The stabilizer was removed and the deflector is delayed .5 secorids. The highest load bus backswing overvoltage is Fritz Creek, and it is just over 115%. Other voltages are under 115%. Only Fritz Creek voltage is above 110% for more then .5 seconds. The deflector was delayed only one half second in this case, not enough to fully remove its impact on backswing overvoltages. Additional delay could be used. The stabilizer was disabled for this case, but its effect on backswing overvoltages could be limited by cutting stabilizer output to zero when voltage is above some threshold, or reducing stabilizer gain as voltages rise above some threshold (e.g. 108%). This capability is not normally provided in stabilizer circuitry, but can be added if necessary. The backswing overvoltages can alsa be reduced by increasing the size of the TCR at Soldomma. Case 206 is similar to 205 except the TCR is increased by 10 MVAR to give the SVS an overall range of +30/-35 MVAR (65 MVAR TCR). In this case only Diamond Ridge and Fritz Creek (and Bradley) voltages go above 110% during the backswing (to a maximum of about 115%). If the SVS “underexcited range" is increased beyond -15 MVAR to control backswing overvoltages,. the reactors and thyristors need only be designed to operate briefly in this range. Power Technologies, Inc. 90 MW Export Export levels as high as 90 MW are feasible with one SVS, three series capacitors, two 25 MW braking resistors, and stabilizers at Bradley. However, there is little stability margin at 90 MW export, and backswing overvoltages will be somewhat higher than desired, but if the system is healthy, it will withstand a three-phase fault close to Bradley Lake on the Bradley Lake to Soldoma line. The ability to export 90 MW comes primarily from the fact that the compensation is designed to allow Bradley Lake to operate at 120 MW with Bernice and Cooper generation off. Adding units at Cooper and Bernice is necessary to increase export to 90 MW, and improves stability enough to allow such operation without exhausting the margin built into the reference case (Bradley at 120 MW, low Kenai load, Bernice and Cooper off). At 90 MW export, the system is closest to its first-swing stability limit. Dynamic and steady state stability margins are reduced at 90 MW, but are more substantial than the first swing margin. This difference occurs because the Bernice and Cooper generation contribute somewhat more to dynamic and steady state stability than they do to first swing stability. However, at 40 MW the Bradley brake is adequaté for this operating condition. Though case 168 shows that the system may be operated at 90 MW export with one Bernice unit and one Cooper unit on-line, the results cannot necessarily be extrapolated to all conditions under which high export might be achieved. For example, the system stability may be different with Bradley Lake supplemented by just Bernice units or just Cooper units, or with a different dispatch in the Anchorage area. Though these differences should not cause dramatic differences, there may be some under which 90 MW export would be less stable than shown in case 168. If operation at 90 MW export is to occur frequently or must occur under conditions substantially different from those examined in case 168, additional cases for those conditions should be run to ensure that they are stable. Though operation at 90 MW export will be feasible with the compensation equipment outlined above under at least one operating condition, an increased compensation level should be considered if operation at 90 MW is to occur on a regular basis. That is, if it is to occur under emergency or unusual operating conditions that will exist for only a few hours or over a period of a few days each year, then additional compensation is not warranted. However, if such operation is to occur every season for a period of some weeks, then the SVS upper limit should be increased to 25 MVAR. The SVS low limit of -25 MVAR as justified elsewhere in this report should be retained. 13 Power Technologies, Inc. Reduced Runback With Bradley Lake power runback from 120 MW to 90 MW or less following tip of the line from Bradley to Soldotna brings loading on the lines from Diamond Ridge to Soldoma within the summer overload capability of these lines. During the winter, however, the rating is higher, and a lower Bradley Lake power runback could be accommodated if stability can be maintained. Case 166 was run to assess equipment requirements to do this. Power flow case P2CA was first run to check post-disturbance conditions with Bradley Lake run back 11 MW to bring loading on the Diamond Ridge to Anchor Point line within its winter emergency rating (assumed to be 110% of the 91.2 MVA continuous winter rating -- 100.3 MVA) under low Kenai load (40 MW)’ As shown in power flow case P2CA, the Soldoma SVS must provide 25.3 MVAR to hold Soldotna voltage under this condition. To provide margin for dynamic stability and to ensure steady state stability, the SVS was increased to +30/-15 MVAR for the stability test outlined below. Stability case 166 shows that the system will survive fault (three-phase) and trip of the line from Bradley to Soldotna with runback limited to 11 MW when the Soldotna SVS range is +30/-15 MVAR. However, note that the SVS is close to ceiling in the seconds after the large first-swing. In earlier cases with runback to 90 MW (case 161), the SVS was 10 to 15 MVAR from ceiling in the final seconds of the simulation. Case 166 thus is closer to stability limits than previous similar cases (e.g. case 161). Note particularly that the oscillations between 2 and 5 seconds in case 166 are lightly damped because the SVS is on ceiling for a total of about 1 second between 2 and 4 seconds (i.e. it has only limited ability to provide damping in this period). An additional 5 to 10 MVAR would be required for case 166 to be as secure as similar cases with Bradley power run back to 90 MW. However, if case 166 represents a condition that will be observed infrequently, the lower margin may be acceptable. Because, as noted above, the steady state SVS output some minutes after the disturbance will be at 25.3 MVAR, and the simulations show poor damping with a 30 MVAR SVS, the SVS upper limit should be increased to 35 MVAR if runback is to be limited to 11 MW. To be fully comparable (i.e. to have the same margin) as the cases with runback to 90 MW, the case with runback to 109 MW would require an SVS with an upper limit of 40 MVAR. 2 Loading on the 115 kV line north of Diamond Ridge is highest when load at Diamond Ridge and Fritz Creek is lowest. 14 Power Technologies, Inc. Loss Of Anchorage Tie During Export In order to minimize risk of dropping Kenai load following tip of any of the several line sections between Soldotna and University, the Railbelt utilities have determined that Kenai frequency must remain between 59 and 61.5 Hz following separation from the Anchorage area. Keeping frequency in this range requires: ° ° prompt governor action at Bradley to run the deflectors in at the maximum rate. similar governor action on any Bernice and Cooper units that are on-line at the time of separation. coordination of governor characteristics to minimize motoring and the risk of unit tip (by reverse power relays) during power runback (keeping the combustion turbines on-line reduces the risk of collapse of the Kenai island). droop settings that will allow power sharing among on-line units at the reduced plant loadings. a change in governor speed reference to bring post-separation frequency into the range 60 to 61 Hz. frequency regulation capability to accommodate normal load variations and restoration of any load that is dropped by separation (e.g. the fault that initiates separation). control of voltage sufficient to not cause generator trip by loss of excitation protection or loss of load due to low voltage. Most of these requirements are associated with the dynamic response of the power plants, the system loads, and the SVS. Simulations are essential, for instance, to show that CTs are not "motored" off the line (tripped by reverse power relays) during the power runback. Initial Overspeed The first task is to limit the initial overspeed. A fault that causes loss of the tie will, itself, cause rapid Kenai generator acceleration by momentarily depressing load and export, 15 Power Technologies, Inc. and by causing motor contactors to open thereby reducing Kenai load. Once the tie is open, the power flow to Anchorage is interrupted, and there is further acceleration. It is desired that the overspeed be limited to 61.5 Hz if practical. The cases described in the following paragraphs examine the basic overspeed problem, and the use of the Bradley brake and Bradley unit tripping options individually and in concert to limit overspeed. All explore a very high export level. Case 181 is for loss of the tie to Anchorage when export is at 90 MW and Kenai load is low (42 MW). With export high and Kenai load low, the Kenai area overspeed will be the greatest. Survival of the Kenai area is most likely if generators at Bernice and Cooper remain on-line through the disturbance because they increase area inertia and will provide better frequency regulation following the initial speed excursion. Case 181 represents a worst-case condition in that the separation is preceded by a three-phase fault at Soldotna (on the line to Quartz). This fault depresses area voltage and accelerates the Kenai generation even before the separation occurs. The overspeed is further aggravated by loss of 20% of the Kenai load (south of Soldotna) during the fault. The load is modelled as 60% motors to ensure accuracy of the simulation (1/3 of the motors are dropped during the fault). In case 181 one Bernice generator is on-line and has a typical combustion turbine governor. Because the Bradley governor is not yet defined, and because it would surely Tamp down at the maximum rate once the overspeed is detected, it is represented as a linear ramp from 120 MW down to 30 MW over a 1.2 second period. The actual governor would probably overshoot somewhat, and hold turbine power low until frequency is closer to its droop characteristic (depending on whether the governor is proportional or integral type). If all of the machines have a droop setting of 5%, and are operating near full rated power before the disturbance, the Kenai system frequency will settle at about 62.4 Hz (for the situation of case 181). In case 181 the Bradley Units are ramped back to 30 MW, just 2 or 3 MW below the total area post-disturbance load. As a result, the frequency is dropping only very slowly after the overspeed condition is arrested. The combustion turbine is limited to just a couple of megawatts of reverse power with the model data used in this case, while the actual control is likely to go further negative (because of the large compressor load on the turbine). The SVS is on its lower limit through most of the run, but the output is rising near the end of the run, indicating that the SVS and associated Soldotna capacitors may be able to handle the voltage in such a case without tripping of Soldotna mechanically switched capacitors. However, note that the Bernice Lake excitation is quite low, so tipping some of the capacitors may be a good idea. This can be done under SVS conrol 16 Power Technologies, Inc. (i.e. if the SVS remains on its lower limit for more than 2 or 3 seconds, it should initiate trip of some of the Soldotna capacitors). The Bradley Lake stabilizers remain fully active in case 181, and contribute significantly to the high voltages in the first second after the separation. To the stabilizer the overspeed looks like the first of a series of speed oscillations due to poor damping. It is possible to remove stabilizers from service during large speed excursions, but has always been undesirable because it is difficult to distinguish between speed excursions due to damping and those due to other causes. It is also difficult to define logic to bring the stabilizer back on-line. For instance, it is quite possible to have overall system frequency tise rapidly and remain high without loss of interconnections so that the system is in a state in which the damping from stabilizers is essential. Digital stabilizers offer a solution to this problem. The stabilizer output can be clipped when voltage at the plant rises above some threshold such as 110%. This can be done without taking the stabilizer off-line. Since high voltages are momentary (1 to 2 seconds) while the damping problem is a longer-term problem (2 to 10 or 20 seconds), the temporary loss of stabilizer action is not a problem. Also, if the reduction in stabilizer output is made proportional to the voltage excursion above some threshold such as 110%, the stabilizer output is only totally suppressed if the voltage exceeds about 115%. With the duration of total loss of stabilizer effectiveness is very short. Case 181A is similar to 181 except that the Bradley brake is used to reduce the overspeed. The brake is applied 6 cycles after the fault is applied (2 cycles after the fault is cleared). A severe fault at Soldotna would trigger the brake somewhat more quickly than this, but an overspeed trigger might be somewhat slower (an overspeed tigger would be needed to apply the brake when separation from Anchorage does not follow a fault). The brake is left on for .7 seconds because at this time the brake is planned to have a thermal duty cycle of just .75 seconds. A longer duty cycle could be provided if the brake is deemed useful in limiting overspeed following separation from Anchorage. Case 181B is also similar to 181 except that one Bradley Lake unit is tipped about .3s after the fault is applied. The frequency is about 61.4 Hz when the unit trip occurs. The remaining unit is run back to 20 MW and held at that level. The final frequency will be under 62 Hz in this case if the two machines (Bernice and Bradley) have the same droop and start at about the same loading (in percent of rated power). 17 Power Technologies, Inc. To demonstrate the use of the brake, unit tipping, and governor speed reference change, case 211 was run. The following were simulated in this case: oO A simple governor with 1.1 second time constant is modeled at Bradley. Its response to overspeed is delayed .4 seconds to conservatively represent the initial delay in the deflector mechanism. Soldoma switched capacitors (MSC) are taken off 15 MVAR at .4 second and 15 MVAR at .8 seconds (assumed to be under control of the Soldotna SVS). The Bradley brake is 50 MW (2 X 25 MW) and is applied at .2 seconds and removed at .8 seconds (.1 seconds less than the presently planned thermal capability). One Bradley unit is tripped at .4 seconds (its brake is left on). 7.5 MW (about 20%) of Kenai load is dropped during the fault. The fault is three-phase at Soldotna and causes immediate trip of the 115 and 69 kV lines to Quartz Creek (conservative assumption since the 69 kV line tip would be delayed and would reduce initial acceleration somewhat). The export is 90 MW when the fault occurs. Bernice unit 3 is operating at 24 MW. Bradley is at 120 MW. Governor speed references are dropped 50% at .4 seconds (this would restore the island to 60 Hz if the loading on remaining machines drops to 50% of initial loading). The Bradley Lake stabilizers are not disabled and do not have gain reduced during the period of overvoltage. The result of these assumptions is overspeed limited to just over 61.4 Hz, voltages below 110% except for two .2s excursions to about 111%, and Bernice combustion turbine power reversal of less than 1 MW, lasting less than .5 seconds. Though many assumptions were made for this case, and all may not be conservative, it is clearly possible to limit Kenai overspeed to less than 61.5 Hz when Kenai export is below 90 MW. 18 Power Technologies, Inc. Case 211 is based on the assumption that three-phase reclosing will not be used on the Kenai-Anchorage tie, or will not be used at the export levels that will require unit tripping to control overspeed. When three-phase reclosing is in use, Bradley unit tip must be delayed and then implemented only if the reclose is not successful. The controls necessary to limit overspeed to 61.5 Hz or less include: ° Carrier or microwave signals from relays on the Kenai-Anchorage tie to Bradley and Bernice. Bradley unit trip and/or brake switching and governor speed reference changes should be initiated by relays that will open the tie due to faults or loss of synchronism -- when export is above some threshold. The speed reference change should vary with Kenai export if practical. ° Local control that will apply the braking resistors when frequency reaches about 60.5 Hz and is rising at a rate of 2 Hz per second or more, and will remove the brake when frequency falls below 60.5 Hz or the brake reaches its thermal capacity. This control should not interfere with the brake controls that apply and remove the brake for faults that initiate stable power-angle swings (such swings do not cause frequency to exceed 60.5 Hz). Planning studies should be sufficient to ensure that the equipment necessary to achieve the desired control will be in place. Operating studies should be conducted to determine how the controls should be set and used under various operating conditions. Unbalanced Dispatch The division of power among the units following the initial overspeed period is important. If all units operating at the time the tie is lost are to remain on the system, all must be at positive output following the initial overspeed. Any units operating at negative power will be tripped after several seconds by reverse power relays. The operating point of each unit after runback to control overspeed will depend on droop settings, initial operating points, and the amount of runback required. If all units have about the same droop, any unit operating substantially below the other units (in percent of rated maximum power), is likely to be tipped by its motoring protection when a large power runback occurs. The droop can be adjusted to give equal loading or some desired distribution of loading after runback for a given initial set of 19 Power Technologies, Inc. loadings and amount of runback. However, this requires software at a central location with access to the present loading on each unit, and the ability to reset the droop on each unit to accommodate the present operating condition (i.e. give desired loadings after loss of the tie). The PC based Bradley governor could easily accommodate this novel system. The Bernice Lake CTs may not be amenable to such control. If the CTs can accept this control or be modified to accept it, it is suggested consideration be given to such a system. Frequency Regulation If the Kenai area is to survive islanding when only Bradley Lake is in operation, the Bradley governing system must be able to follow load with sufficient response to keep frequency within a reasonable band (59 to 61.5 or better). In addition to normal load variations, there are two phenomena that will impose significant load changes on the system after islanding (loss of the tie to Anchorage). If the Anchorage tie is lost as the result of a fault that is either severe or close to Kenai loads, some motors in the Kenai will be dropped from the system. These motors will be restarted over a five to 10 minute period following loss of the te. If 10 MW of motors is dropped, and return over a five minute period (pessimistic assumption), the load rise may be as much as 2 MW per minute. If voltages in the Kenai drop as the result of loss of the tie, residential and commercial loads will be reduced. LTCs will restore distribution voltages, thereby causing an increase in load over a period of 2 or 3 minutes after the disturbance. Similar loads not served by LTCs will be partially restored over a period of 10 to 15 minutes by the action of thermostats and similar controls and some manual control actions. In order to keep frequency from falling below 59 Hz as a result of these load increases, the needle valves at Bradley must be able to “follow” the load with only a modest time lag. The needle valves have a full-stroke time of 90 seconds. Hence one Bradley unit can provide .67 MW per second to meet load changes. Two units can provide 1.33 MW per second. This capability should allow the Bradley unit to follow all normal load variations and natural load restoration following faults without excessive frequency variations. However, step changes in load may be troublesome. A sudden large increase in load will cause the needle valves to begin moving quickly, and may cause a momentary drop in pressure at the nozzles. This drop in pressure will momentarily reduce the power produced by the Bradley turbine, and thus will contribute to the frequency decay caused by the step increase in load. This phenomena may limit the size of load step that can be 20 Power Technologies, Inc. accommodated without allowing frequency to drop below 59 Hz. More information on the turbine-penstock system and appropriate modeling (including system effects noted in the next paragraph) is required to determine precisely the limit to the step load that Bradley can handle while avoiding load shedding. The Bradley plant will have the assistance of load-frequency characteristics in preventing large frequency changes when loads increase. The loads themselves will drop with frequency, thereby helping to offset load increases. For instance, if the over-all load- frequency characteristic is 1% drop in load for 1% drop in frequency (it may be more than this), a 1 MW increase in a 50 MW load will cause frequency to drop only 1.2 Hz even without help from generator controls or the natural damping characteristic of the turbine. The benefit of load-frequency characteristics will not be available when the load is low or near zero. When loss of the intertie causes load shedding, restoring loads dropped by load shedding relays could impose sizeable step increases in load (including the cold-load-pickup effect). Restoring any feeders that would hit the system with more than about 2 MW are likely to cause additional or repeated load shedding (detailed simulations mentioned above are needed to provide accurate prediction of the maximum step load that can be accommodated without dropping frequency below 59 Hz.)* It may be necessary to restore loads at lower voltages (i.e. in smaller steps) when Bradley is the only generation operating in the Kenai island. Frequency Control Following loss of the tie and runback, the frequency will settle well above the pre- disturbance frequency. If the droop settings are 5% and generator power must be reduced by 60% of rated power to balance load, the speed will increase 3% (to 61.8 Hz). If one Bradley unit is tripped, the final frequency will be about 61 Hz. If one Bradley generator is not tripped when runback of more than about 40% of the Kenai on-line generating capacity is required, the governor speed reference settings on all generators will have to be reduced to keep final frequency under 61.5 Hz. Even when unit tripping will bring the frequency to about 61 Hz without speed reference changes, the reference changes are advisable to get the system as close to 60 Hz (but not below 60 Hz) as practical. ‘ Operators can reduce the risk of frequency excursions below 59 Hz following islanding by setting system frequency somewhat above 60 Hz until all loads are restored. Power Technologies, Inc. The speed reference settings can be set quickly from a central location where there is sufficient information to calculate the new settings. The settings must be changed within quickly if the change is to prevent frequency from going over 61.5 Hz. Alternatively, the speed references can be changed based on the initial overspeed event. That is, the initial overspeed could trigger the change in speed references. A risk with this approach is that a system-wide frequency excursion of similar proportions could trigger the change in speed reference, thereby reducing power produced by Kenai generation until the settings can be restored through SCADA or by operator action. However, it is extremely unlikely that the whole system could reach 61 Hz and sustain a rate of rise at that frequency comparable to the Kenai generation following loss of the tie to Anchorage, making this approach worth considering. Bradley Lake Governor The Bradley Lake governor consists of a deflector and needle valves in each jet. At maximum closing rate the deflector can reduce turbine power by 100% in 1.5 seconds. At maximum closing rate the needle valves can reduce turbine power by 100% in 90 seconds. The deflector thus must be used when fast control is required, and the more efficient and precise needle valves can provide steady state regulation. The deflector and needle valves are to be controlled by a programmable controller that is being prepared by Woodward. This control must be designed to take maximum advantage of the deflector response characteristics in order to meet the goal of keeping Kenai frequency within the range 59 to 61.5 Hz following loss of the Anchorage tie. The digital control can be very precise, limited only by its speed sensing circuit and limitations and limitations associated with the deflector linkage and the turbulence of the stream. One control strategy is to supplement needle valve control with the deflector control when frequency rises above the needle valve droop characteristic by more than some amount such as .25 Hz, then return the deflector to the edge of the water stream when frequency returns to within .25 Hz of the droop curve under needle valve control. This requires that both the needle valve control and the deflector control be simultaneously active in some operating conditions, and also requires that the deflector control be idle when it is not needed, and activated when necessary to limit overspeed. To achieve the full potential of the PC based controller, it is essential that the deflector and needle valve operating characteristics be well known and taken into account in its design. Final design should be based on simulations of the complete plant and the associated electrical system. Power Technologies, Inc. Specification and Operations Planning Studies Though the basic mechanisms to limit risk of frequency and voltage problems upon separation between the Kenai and Anchorage areas are well defined above from a planning standpoint, additional power flow and stability cases are essential to specify contol equipment to meet all the various system operating conditions that can occur. Beyond this, yet additional simulations are needed to define operating procedures and control equipment settings that will make best use of the available equipment under an even wider range of operating conditions. Such studies must be repeated from time to time as system conditions change. Examples of the details that need attention include: ° Calculation of load sharing among the several remaining machines based on droop characteristics. The droop characteristics should each be adjusted specifically to ensure sharing of load when there is a sudden reduction of up to 70% of area generation. These are essentially hand calculations, but demonstration of the load sharing following the initial overspeed can be confirmed in the simulations outlined below. Simulations of the dynamic response of the three plant governing systems to ensure coordinated response to the overspeed and reasonable sharing of the load drop. If loading is not well balanced the CTs may see sufficient reverse power to develop flame stability problems during the runback. Adjustment of reverse power relays so they will ride through temporary reverse power following loss of the Anchorage tie (based on simulations listed above). Simulation of the voltage excursions following loss of the Anchorage tie for several Kenai load levels and generation dispatches to ensure that the SVS controls designed to improve stability will also accommodate islanding. Voltages must be sufficiently well controlled to ensure that generator loss-of- excitation protection will not operate during the initial voltage excursions or later in the post-disturbance steady state condition (SVS control of the Soldotna MSCs will be important). Simulation to select settings for controls such as the overvoltage and overspeed cutout on the Bradley Lake stabilizers. Simulations to select settings for controls on the Bradley braking resistors (for both turn-on and turn-off) and Bradley unit tripping. The relay and associated 23 Power Technologies, Inc. carrier or microwave communication details between Soldotna/Quartz Creek/Dave’s Creek and Bradley also need to be defined. The maximum overspeed reached in case 181 is about 3.6 Hz, or about 6% above rated speed. The Bernice Lake CTs have an overspeed trip set at 5% above rated speed. Though the overspeed can be reduced to less than 5% by use of the brake and/or unit tipping even at 90 MW export, it would be desirable to raise the Bernice CT overspeed trip settings to 6% to increase the margin between expected overspeed and the trip settings. Doing so will reduce the risk of nuisance trip should the system not be fully healthy at the time of separation, or some control equipment not function quite as desired following separation. Use Of TSC Rather Than TCR/MSC Early Phase II studies included a look at the ASEA 7.2 MVAR Minicomp. This is essentially a small SVS in the form of a group of thyristor switched capacitors (TSC). The potential benefits of such a unit would include: ° Reasonable cost and high reliability because it is a factory built unit. ° Improved performance from distributing the compensation across 4, 5 or 6 substations (several small SVSs are typically more effective than fewer large ones -- though the cost per kVAR increases dramatically as the size is reduced). The minicomp was also considered because in all scenarios examined, the net shunt compensation is positive. That is, even when a +20/-25 MVAR unit is applied at Soldoma, the net compensation is capacitive because the unit is in parallel with a 30 MVAR mechanically switched capacitor (MSC) bank. Note however, that to avoid need for any thyristor controlled reactor (TCR) capacity, the MSC equipment at Soldotna would have to be replaced with a minicomp. Power flow cases 2HA and 2HB show, however, that an optimum distribution of the minicomps is not one per substation along the 115 kV system, but four units (28.8 MVAR) at Kasilof and two at Soldotna. These cases are based on steady state conditions following loss of the Bradley - Soldotna line. Additional TSC capacity at either or both locations would be necessary for stability. Cases 2HA and 2HB show that reactive sources are best placed at Kasilof and Soldotna, though other casework shows Quartz creek to be a 24 Power Technologies, Inc. somewhat more advantageous location. The need to lump the reactive sources as shown in power flow cases 2HA and 2HB comes about largely from the high resistance lines between Diamond Ridge and Soldotna. Because of the resistance, northerly power flow causes a voltage drop that is offset by southerly reactive flow. Reactive power injected at Quartz Creek and Kasilof flows largely southward. Stability cases showed that the minicomp was no more effective than two large SVSs, and in fact was essentially just that when several 7.2 MVAR units were grouped at Kasilof and Quartz Creek. Additionally, to use the minicomps effectively, some or all of the MSC equipment at Soldotna would have to be replaced with one or more minicomps. Replacing some of the MSC equipment at Soldoma with TSC equipment may be a good idea if doing so is more cost effective than adding a large TCR to offset the capacitors during backswings, oscillations, etc. However, a single large package of appropriate equipment is sure to be less costly than replacing existing MSC with several minicomps. Line/Transformer Drop Compensation Voltage control in the Kenai can be improved by using the Bradley Lake voltage regulator to control voltage well out on the Bradley-Soldotna and Bradley-Fritz Creek lines. This can be done by adjusting the voltage regulator line/transformer drop compensation for an impedance greater than the stepup transformer impedance. This benefit can also be provided manually if the operators are instructed to raise Bradley 13.8 kV voltage when the reactive power out of the plant his high (i.e. indicating low voltages in the Kenai 115 kV system). However, if it is provided automatically by a line/transformer drop compensator circuit, the regulator will not only hold voltage away from the plant in the steady state condition, but will be somewhat more responsive to reactive power swings. This can help first-swing stability. Unfortunately, it pushes up the machine flux during the first-swing, and this flux is sustained during the backswing by the stabilizer. The net effect is backswing overvoltages 2 to 3% higher than they are without the line/transformer drop compensator (compare cases 157 and 159 respectively). Hence line/transformer drop compensation is recommended at Bradley Lake only if it can be provided with its own slow time constant, or is set only to reach into the stepup transformer. It would be highly advantageous to apply the line/transformer drop compensation through a time-lag that would prevent it from responding at first-swing and damping frequencies, but would allow it to adjust the exciter operating point slowly to accommodate steady state conditions. Aside from improved voltage regulation in the Kenai area, the line/transformer drop compensation would improve steady state stability of the plant measurably. Power Technologies, Inc. The series capacitors and the SVS at Soldotna are designed to ensure steady state stability with the Bradley Lake voltage regulator holding Bradley 13.8 kV bus voltage. However, the stability margin will be increased if the Bradley voltage regulators can hold voltage out on the 115 kV lines. Also, extending the voltage control point out on the lines may maintain steady state stability during some operating conditions (unusually high export) or equipment outages (SVS outage) that might otherwise be unstable. An additional note: The system can be expected to be steady state unstable under moderate to high Bradley Lake generation and/or high Kenai export when the Bradley units on “hand control" -- i.e. with regulators off and voltage controlled manually. Such operation must be avoided. SVS Size and Design The SVS recommended in this study is to have a dynamic range of 55 MVAR (from +30 to -25). However, the SVS need not be capable of continuous operation over this complete range. Operation below 0 MVAR can and should be made infrequent by proper control over the MSC at Soldotna. Operation below 0 MVAR will be temporary as it will occur during backswing overvoltages and loss of load or system breakup. Hence this portion of the dynamic range can be provided by short-time rated components, or by component overload capability. This opportunity will be covered further in the Phase II report. Load Rejection Overvoltages The large amount of capacitors at Soldotna present some risk of “load rejection overvoltages." The potential for damaging overvoltages has only been examined briefly in Phase II, but needs to be considered further before Soldoma substation equipment changes to accommodate the SVS are finalized. This problem will be considered further in Phase Il Preliminary Specifications), but some consideration of the problem at this time is useful in that it may affect decisions regarding the SVS size and placement. Load rejection overvoltages occur when line tipping, often involving operation of backup protection, leaves line or cable charging or capacitors connected to a weak source. In the case of the Soldoma capacitors, a problem that opens the lines to Ski Hill, Bernice Lake, and Bradley would leave the SVS and capacitors on the long radial line from University to Soldoma. The line loading will drop, leaving the reactive power from the 26 Power Technologies, Inc. capacitors to flow all the way to the Anchorage area to be absorbed by load or generators. The voltage at Soldotna would be very high, possibly high enough to cause arrestor failure or flashover of the 115 kV line or bus. If the high voltage does not cause a fault the system, it can cause a breaker to fail if that breaker attempts to open under the high voltage and high leading current The overvoltage would be particularly severe if the SVS is operating at maximum output at the instant the system lands in the radial load rejection situation. With the SVS TCR gated off, the capacitors associated with the SVS (20 MVAR) plus the existing capacitors (30 MVAR) would total 50 MVAR. The voltage would be brought down only after 1 or 2 cycles when the SVS overvoltage protection gates the thyristors into full conduction. Flashover or arrestor failure can occur during this brief period of excessive voltage.° The existing system is probably at higher risk of these potentially damaging load rejection overvoltages than the system will be in the future. The SVS and added line to Bradley will reduce risk of overvoltages. However, the risk may still be excessive, and it is prudent to begin now to determine if the problem will remain, and if it does, to define solutions. Possible solutions include: ° Increase the size of the TCR (though this will not help the first cycle overvoltage when the SVS is on ceiling).° ° Apply metal oxide varistor (MOV) type surge protection to absorb energy and thus hold voltages down until capacitors can be switched off. ~ ° Arrange the substation (breakers and protection) so that radial load rejection is very unlikely. 5 The SVS controls can be designed to gate the TCR on full when a fault occurs, and then return to the voltage regulation mode when the fault is removed in order to avoid high voltage upon fault clearing. § Where an SVS driven to ceiling by faults presents potential overvoltages immediately following fault removal (or resonance problems during the fault), it may be necessary to gate the TCR thyristors full on during the fault, and then resume voltage control following fault clearing. Power Technologies, Inc. ° Initiate trip of the capacitors for any relay or breaker operations that are likely to leave the system in a situation wherein voltages would be excessive. ° Locate the capacitors so they are unlikely to become isolated with a weak source. Two power flow cases were run as a preliminary assessment of the potential for damaging overvoltages at Soldotna. With all lines into Soldotna opened, the 30 MVAR of capacitors left on line, and the Quartz 115 to 69 kV transformer removed, the Soldotna voltage is 147% and the University 115 kV bus voltage is 106%. Under the same condition with 50 MVAR on the Soldotna bus, the voltage is 184% at Soldotna and 110% at University 115 kV bus. The Soldotna capacitors could also cause high voltage if isolated with less than 40 to 50 MVA of Bernice Lake generation. The Bradley generators are large enough to avoid a high voltage problem should one of them become isolated with Soldotna capacitors. Brake Control Considerable detail on the application and control of the Bradley braking resistor will be presented in the Phase III report (Preliminary Specifications). However, several cases were run to determine how critical the brake application time is in terms of stability, backswing overvoltages, and inadvertent brake application. These cases are discussed in this section. Early removal will result in first-swing instability. Late removal will result in large backswing overvoltages, and may cause large power oscillations that the SVS and Bradley stabilizers cannot overcome (i.e. they will be undamped instead of damped). Cases 193 through 196 explore the consequences of inappropriate brake application times for the worst-case operating condition (low Kenai load, Bradley at 120 MW, and Bernice and Cooper off) for the worst-case fault (fault and tip of the line from Bradley to Soldotna) with results as follows: Power Technologies, Inc. DURATION RESULT 3s first-swing unstable 4s near optimum in all respects (.39s is optimum for this system condition) oS large but tolerable back swing overvoltages .6s excessive backswing overvoltages and large but damped post-first- swing oscillations Though the .3s case (193) is clearly unstable, removing the brake at anything less than the optimum time is risky. Cases 154 and 155, though not otherwise exactly the same as cases 193-196, show the results of removing the brake early but not so early that first- swing instability occurs. In case 154 the brake is too small and is removed too soon, in case 155 the brake size and switching time are optimum. Rather, the subsequent large oscillations result in dynamic instability. The brake duration should be optimum or greater than optimum, but not less than optimum. The .6s case (196) shows large post-first-swing oscillations, but they are well damped at the export level examined in this case (damping may be a problem at higher exports if an excessive brake application time initiates large oscillations). It thus does not appear that moderately excessive brake durations carry high risk of dynamic instability as was suspected from some early casework. The improved tuning of stabilizers and other minor differences seem to have reduced this risk. However, leaving the brake on longer than necessary does give rise to larger backswing overvoltages. Some voltages exceed 120% in this case. It should be noted that these cases were run with a detailed load model that includes saturation in motors, transformers, customer loads, and discharge lighting, so the voltages observed are not pessimistic: They are quite representative. Case 204 provides additional information. This case is for trip of the line from Bradley to Soldotna without a fault, and with the brake applied for 0.5s. The deflector is also run in to 90 MW. This case was selected because, the brake, if needed for this case, would have an optimum duration of just .1 or .2 seconds while the duration, if it is to be fixed, must be .4s or more to ensure stability for more severe faults. This case shows that a longer duration is not a problem for this disturbance. Power Technologies, Inc. Case 179 was run for inadvertent application of the brake during low export. Inadvertent application of the brake will cause the largest swing under this condition. This case shows that the brake is not a threat under such conditions. Case 197 shows similar results under heavier export conditions. These cases show that a sensitive brake trigger can be used without risk of causing instability for minor disturbances such as lower voltage faults. The above cases show a relatively large tolerance for the brake duration so long as it is equal to or greater than the optimum time. However, the tolerance is really just .1 seconds or 6 cycles if high backswing overvoltages are to be avoided. The duration will be more critical for higher exports such as 90 MW. That is, extra brake duration will cause increasingly high backswing overvoltages and oscillations as the export is increased. The brake time will also vary somewhat depending on the level of runback. It must remain on longer when runback is reduced to take advantage of the winter Diamond Ridge line overload capability. To ensure that the brake is not removed too quickly, and does not stay on so long that it causes dynamic instability or troublesome backswing overvoltages, it is highly recommended that provision be made to remove it 3 cycles after the peak of the angular swing. This can be done by digital controls at Bradley. The computer would monitor Bradley rotor speed continuously, and each time the brake is applied by undervoltage relays, the computer would send a trip signal to the brake circuit breaker when the rotor speed returns to its pre-disturbance value (or .7 seconds, the maximum brake duration). The logic of the brake controller can be modelled and tested in the same simulation environment used for this study. If digital stabilizers are used at Bradley, the brake control function can be implemented in the same cpu or a tandem cpu in the same equipment. This will be a reliable approach because there will be two stabilizers at Bradley, one on each unit, either of which can control the brake. Power Technologies, Inc. BRADLEY LAKE LIMITED TO 90 MW A stability case was run to extend the conclusions drawn from cases 123A through 123D in the Phase I report. Those cases indicated that with Bradley Lake power at 90 MW and Bernice and Cooper machines on-line, the system would be stable with only the Bradley brake and the Bradley deflector as stability aids. Case 200 was run to determine if stability could also be maintained with just these aids if Bradley Lake is the only generation operating in the Kenai area. The base case includes only Bradley Lake in operation in the Kenai, 40 MW Kenai load, 42.5 MW of export, and all but 10 MVAR of the Soldoma shunt capacitors switched off. Case 200 includes detailed load models and loss of load during the fault. The disturbance is a three-phase fault near Bradley Lake on the line to Soldotna followed by trip of the line at 4 cycles. A 40 MW brake is used, and the deflector is used to run power back to 60 MW over 0.4 seconds starting at the instant of fault clearing. The case is stable. The brake is removed at .35 seconds, indicating some margin for a longer duration fault or a higher bradley Lake power level. The system is shown to be lightly damped, but since the system model includes detailed motor models the simulation should be accurate enough to justify accepting the light damping. Voltages in the Kenai all appear likely to settle between 95 and 100% in the seconds after the fault. The voltages will be even lower after a minute or two when distribution voltages have been restored by LTCs. In order to ensure continued stability in this case, Soldotna shunt capacitors would have to be switched on within about 1 minute after the fault occurs. This would be the case regardless of the cause of tip of the line from Bradley to Soldotna. Altematively, Bradley could be ramped to a lower level such as 50 Mw. SVS ALTERNATIVE Fifty percent series compensation of three of the longer lines in the Kenai area, combined with one SVS at Soldoma has been shown to meet Bradley Lake stability objectives. Hence this solution to the stability problems associated with the existing 115 kV system is recommended for consideration. However, a second alternative utilizing two SVSs and no series capacitors will also meet stability requirements, and may have advantages important to the railbelt utilities. 31 Power Technologies, Inc. Several cases were run to explore an all-SVS option. This option may become important if it is found that the lower cost series capacitor option presents design or operating difficulties associated with subsynchronous resonance. The cases focus on SVS size and damping controls, and address only the worst-case disturbance; fault and tip of the line from Bradley to Soldotna. In these cases it is assumed that the deflector will not cut in quickly enough to aid first-swing stability (the deflector is assumed to reduce power by 30 MW between .6 and 1.5 seconds). Stabilizers are not used on the SVS in these cases. The MSC at Soldotna are set at 15 MVAR and is unchanged in the simulations. Case 208 shows that two +50/-10 MVAR SVSs, one at Quartz Creek and the other at Soldotna, will provide complete stability. However, the full range of SVS capability is not used at either location. Case 209 shows stability with two +35/-0 MVAR SVSs. Neither SVS reaches ceiling during the first-swing, indicating the possibility of further size reduction (if allowed by damping and steady state stability). The Quartz Creek SVS peaks at about 33 MVAR while the Anchor Point SVS reaches about 27 MVAR (both hit ceiling during the fault, but reactive supply during this period has negligible impact on stability). Case 209 was also used to assess need for stabilizers on the SVS. SVSs contribute significantly to damping without stabilizers, so the cost of stabilizers can often be avoided. However, it is highly desirable to have some margin, or redundancy, so that the system will remain stable during forced outages and maintenance outages of stabilizing equipment. Case 209 was run without the Bradley stabilizers to determine if the two SVSs alone would provide adequate damping. Oscillations build quickly even though both SVS are well below ceiling, and thus are providing maximum contribution to damping (ie. the maximum possible without stabilizers). Two additional cases would be useful, one with just one Bradley stabilizer, and one with stabilizers working at Bradley and one SVS out of service. However, even if both of those cases show positive damping, it would be prudent to apply stabilizers to the two SVS to ensure that the system will not be subject to growing oscillations and instability upon loss of a stabilizing device during outage or maintenance of another. Case 210 is similar to 209 except that the Bradley stabilizers are working. The case is well damped. This case shows that +35/0 MVAR is close to an optimum size for the two SVSs. Both peak at close to their 35 MVAR ceiling, and both settle just under 20 MVAR. The zero lower limit is adequate to keep backswing overvoltages under 110%. Power Technologies, Inc. The two-SVS option does not exhibit large backswing overvoltages that a series compensated system does. The reason is that the post-disturbance system angle is much lower in the series compensated system, and the Bradley machines must swing back down to this angle after the brake is removed. The machines accelerate downward as they move back toward the final angle, thus overshooting it and momentarily pushing transfer down close to zero. With SVSs the final angle is much closer to the angle the Bradley machines are at when the brake is removed. Hence there is much less deceleration following brake removal, and little overshoot. With SVSs the modest drop in angle that does occur is largely due to the power reduction provided by the deflector. SVS - Series Capacitor Comparison Though all alternatives for raising the stability limits to Bradley Lake power level and Kenai export involve at least one SVS, the decision between an all SVS solution and one making use of a combination of SVS and series capacitors (SC) should not be based totally on costs and the ability to meet deterministic criteria.’ Some other considerations are presented in this section, and some details will be found in the Phase II report (Preliminary Specifications). These other considerations can affect reliability in ways that are not revealed by tests outlined in deterministic criteria. One of the most important considerations is the ability to handle disturbances beyond the deterministic criteria. Such disturbances are often called “possible but improbable" events or "PBIs.". Though most planning criteria that addresses PBIs indicates that the effects of such disturbances need not be fully mitigated, but should be reduced to the extent practical with modest additional attention to detail or additional equipment. However, when there are two competing alternatives, it is useful to test them against PBIs as a measure of inherent robustness (i.e. the ability to hold together beyond the basic criteria tests). If two alternatives are otherwise equal, the one that is inherently more robust should be selected. The benefit of a more robust alternative may also be judged to have monetary value, and thus offset the high It is usually the case that SC based systems or systems using SCs will survive a wider range of more severe disturbances and operator errors than SVS based systems. Flexibility to accommodate future network expansion or upgrade are also attributes that should be considered in the selection of a transmission alternative. In this regard, the SVS 7 Deterministic criteria is a set of specific and well defined tests that a system plan must pass to be deemed acceptable and fully designed. 33 Power Technologies, Inc. based alternative may be judged to have a small advantage. SVSs, though likely not ideally located for some future system, will usually be useful whatever future development occurs. Series capacitors, on the other hand, may need to be moved or adjusted in size because of line load balancing or SSR problems. The series capacitors require little maintenance, little operator attention, and are very reliable. The absence of controls and the almost total lack of operator attention are probably the most attractive features of series capacitors in the APA system. An SVS, on the other hand, does require adjustment by operators on an hourly or more frequent basis, unless some relatively sophisticated controls are provided to keep the units operating in a mode that will ensure maximum contribution to stability when the system is hit by a fault and line trip. While SVSs have potential harmonic and control problems that must be dealt with in specification studies, series capacitors have their own potential problems. The most significant one is subsynchronous resonance (see the Phase III report for additional detail). It is unlikely, but possible, that subsynchronous resonance problems will rule out use of series capacitors in some or all of the candidate lines in the Kenai. Whether or not this is the case can be determined only after analysis of the potential for subsynchronous resonance, and the possible use of remedial measures to solve the problem. One possible remedial measure is increasing or decreasing the level of series compensation, or remove it from just those lines where it is troublesome. Until such analysis is conducted, it is suggested that the use of two SVSs be considered as a fallback option, and that the economic impact of having to go to this option be recognized as a possibility. If series capacitors cannot be used, then additional study work will be needed to finalize the sizes of the two SVSs and their locations. The locations -- Anchor Point and Quartz Creek -- are fairly well defined and are unlikely to change, however, the sizes, indicated to be +35/-0 in case 208, 209 and 210, should be confirmed by further stability cases (only fault and trip of the line from Bradley to Soldotna was examined in cases 208, 209 and 210 -- 69 kV faults and other 115 kV faults should also be run to confirm the +35/0 MVAR size). If the series capacitor level need only be reduced to avoid SSR problems, then it may be feasible to increase the size of the Soldotna SVS to provide the desired stability performance. It is also possible that increasing series compensation will avoid an SSO problem in which case the Soldotna SVS size can be reduced. 34 Power Technologies, Inc. 230 KV LINE ALTERNATIVE The focus of the Railbelt Stability Study is on alternatives to a new transmission line from the Kenai region to the Anchorage area. However, some analysis of the stability performance of a new 230 kV line has been included as a point of reference from which stability performance of the less costly 115 kV upgrade can be judged. Installing the 230 kV line will allow a reduction in the compensating equipment that would be required for the 115 kV alternative. However, much of the equipment must be retained simply to meet the same stability criteria upon which the 115 kV plan is based. Additionally, if the full potential benefits of a second line are to be realized, some of the compensation equipment that may not be essential to meet the 115 kV system stability criteria, must be retained. With the 230 kV line added to the system, there are two relatively severe disturbances that dictate compensation requirements. One is fault and trip of the line from Bradley to Soldotna. The second is fault and trip of the 230 kV line. First-swing, dynamic (damping), and steady state stability for the worst-case fault (fault and trip of the Bradley to Soldotna line) require that the braking resistor and two series capacitors between Bradley and Soldotna be retained. Runback is not required for stability for exports up to about 75 MW, but may be required at higher exports.* The series capacitor between Soldotma and Quartz and the SVS at Soldotna are not essential. Case 167 shows that the system is first-swing stable for fault and trip of the line from Bradley to Soldotna without the SVS and Soldota-Quartz series capacitor. The braking resistor and runback are essential in making this case stable.? Cases 198 and 198A show that the system is also first-swing stable for fault and trip of the 230 kV line if the braking resistor is applied. Since the 230 kV fault is remote from Bradley, the brake will have to have sufficiently sensitive triggering based on voltage, or be triggered from 230 kV line protection via carrier. Runback may also be sufficient to provide first-swing stability for the 230 kV fault, but since the brake is required for other faults and avoids runback, it is 5 Runback will be required to avoid thermal overload of the Diamond Ridge to Soldoma line under some Bradley power levels, Kenai load levels, and seasons. ° As shown in cases on the 115 kV alternative, the braking resistor size can be increased so that runback is not essential for first-swing stability. Runback may be needed for dynamic or steady state stability, but can meet these requirements, but can be delayed and still meet them. 35 Power Technologies, Inc. the better choice. Also, the speed of response of the deflector is in question at this time and may not allow the deflector to contribute significantly to first-swing stability. Steady state stability is not a problem for either of the two worst-case disturbances (loss of the Bradley-Soldotna line and loss of the 230 kV line), but damping is a problem. It was first observed in case 198A which was extended to 5 seconds to check damping. This case shows essentially zero damping, a totally unacceptable situation if it is accurate. Because this case was run with a conventional simplified algebraic load model, and could be the deciding factor in whether or not an SVS is needed with the 230 kV line, it was rerun (case 199) with the complex load model (includes large and small motors, discharge lighting, saturable exciting current model, etc.). This case shows growing oscillations that will lead to loss of synchronism within 20 to 30 seconds after loss of the 230 kV line. The Bradley Lake stabilizers are active in these cases, but are not adequate to handle the damping problem. Adding series capacitors between Soldotna and Quartz will reduce the damping problem, but is not likely to solve it. Running Bradley Lake power back to 90 MW or less will solve the problem as shown in case 207. An SVS at Soldotna, probably limited to +10/-10 MVAR, would also solve the damping problem. SVSs have been used simply for this purpose in a number of systems, so it is not surprising to have to do so in this case. Though a large SVS would not be required to provide damping, it would have to be operating well within its dynamic range following loss of the 230 kV line. Power flow cases discussed below show that a modest size SVS would go to ceiling or close to ceiling for loss of the 230 kV line. The controller on a small SVS would thus have to be especially designed to provide damping while sacrificing steady state voltage control. If runback is used to solve the problem, it must be triggered within several seconds of loss of the 230 kV line, and should reduce power within several additional seconds. That is, immediate and rapid power reduction is not necessary, but it must be done within about 5 seconds. The amount of runback required is difficult to estimate. Additional stability cases will have to be run to make this assessment. An SVS is the most effective and reliable means to solve the damping problem. While damping will vary with transfer, and reducing transfer can be used avoid damping problems, because damping is so heavily dependent on machine and load characteristics and on the complement of machines that are on-line, studies to define transfer limits (or runback) to achieve damping cannot be highly reliable. An SVS, on the other hand, if 36 Power Technologies, Inc. properly controlled (i.e. not allowed to sit on ceiling) and sized (i.e. with some margin), will easily handle the damping problem for any credible transfer level, dispatch, and assumptions about generating plant and load characteristics. There may be additional justification for providing at least a modest size SVS at Soldotna along with the 230 kV line. Power flow cases P2DA through P2DE cover a range of conditions as follows: P2D Base case with 230 kV line, 25 MVAR 230 kV shunt line reactor at Soldotna, no shunt capacitor bank at Quartz, no series capacitor between Soldotna and Quartz, and the SVS supplying just .4 MVAR (in addition to the 30 MVAR of MSC at Soldotna). P2DA Like P2D except Bradley reduced to 90 MW and the Bradley - Soldoma line open. The SVS is supplying 17.4 MVAR. P2DB Like P2DA except the SVS removed. Soldoma voltage drops from 102.0% to 99.0% P2DC Like P2D except the 230 kV line is out (Bradley remains at 120 MW). SVS is at 9.3 MVAR. P2DD Like P2DC except SVS removed. Soldotna voltage drops from 102.0% to 99.9%. P2DE Like P2D except 230 kV line open at University end. The SVS is absorbing 9.4 MVAR. P2DF Like P2DE except SVS removed. Soldotna voltage rises to 104.2%. Though these voltage variations do not argue strongly for an SVS at Soldotna if the 230 kV line is constructed, they do show that there will be some voltage variations if the line is installed and an SVS is not. If an SVS is not installed, operators can maintain voltages by switching Soldoma capacitors via the SCADA system. In this respect, voltages will be better regulated in the 115 kV alternative. 37 Power Technologies, Inc. If an SVS is to be used to regulate voltage at Soldotna in situations such as those examined in the above power flow cases, it must be sized to provide the voltage regulation and allow for modulation to provide damping. To do this, the SVS would have to have an upward dynamic range of about 20 MVAR, 10 to cover the voltage drop, and an additional 10 for damping. : The above power flow cases were done neglecting any cables that will be required for marine sections of the 230 kV line. This should have little impact on the above conclusions so long as the additional charging from the cable sections is fully compensated by additional shunt reactor capacity on the line. Backswing overvoltages are shown in case 167 to be quite close to the Railbelt voltage criteria. 115 kV load bus voltages swing to about 116%, and are above 110% for about .5 seconds (the criteria allows a maximum of 115% and above 110% for no more than .5 seconds). If an SVS is used to provide damping, it should also reduce the backswing overvoltages somewhat (depending on size and initial operating point). The 230 kV reactor size was selected based on just one load flow case, and does not consider charging from submarine cables along the line route. The actual reactor size and location may thus be different from that assumed for this study. However, since the reactor will largely offset charging, and the two have the same voltage and frequency characteristics, adding the 230 kV cable and changing reactor size and location will have only a very insignificant effect on Kenai stability, but may be important from a steady state voltage control standpoint. The charging current not absorbed by the reactor, taking into account the ferranti effect, must be within the capability of Kenai area reactive control equipment (generators and SVS). This will be especially important during 230 kV line energization, following nuisance trip of the University terminal, separation due to instability, etc. RELIABILITY The 230 and 115 kV transmission alternatives require about the same compensation equipment to provide stable operation, and both will be affected by outages of that equipment. In both cases, the system as planned does not ensure stability for outages of the stabilizing equipment. That is, outage of the SVS, any one of the series capacitors, or the braking resistor, would make the system unstable for fault (three-phase) and trip of the line from Bradley Lake to Soldoma, and possibly for some other severe faults when Bradley Lake power level is high and/or export is high. The SVS and the brake are the 38 Power Technologies, Inc. two most critical items. Outage of one series capacitor would present a problem only for the most severe disturbance (multi-phase fault close to Bradley Lake on the line from Bradley to Soldotna), while an SVS or brake outage may leave the system unstable for loss of the line from Bradley to Soldoma even without a fault. Of the two, the brake is the most critical. The consequence of not designing for redundancy in the critical stability aids is that Bradley Lake power will have to be reduced during such outages to ensure stability, or to reduce the impact on the system if instability does occur. Alternatively, Bradley Lake power level and Kenai export can remain at or close to the desired level at the risk of instability for major disturbances. There are backup measures that can be applied to support increased transfer during outages of critical components. Two examples are increased Bradley runback, and application of generator tripping. Both of these options can be readily implemented when and if operations planning studies show they are beneficial (that is, the hardware and controls that are outlined in this report can be easily expanded to implement these options). The restrictions that must be applied to meet the normal criteria or a reduced criteria during outage of critical components must be established in operating studies or "operations planning" studies. These studies should consist of power flow and. stability studies based on the equipment and conditions that are expected for the future period for which the studies are being conducted. 39 Power Technologies, Inc. APPENDIX I Load Models To ensure accuracy, most of the simulations done in Phase I are based on a detailed Kenai load model consisting of 30% small motors, 30% large motors, 5% discharge lighting and 35% load varying with the 1.5 power of voltage. The reactive load includes a saturable exciting current model set at 5% of the bus real power. Loss of one third of the motors (10% small motors and 10% large motors is simulated in most cases in which there is a widespread drop in voltage during a fault. RAILBELT STABILITY STUDY PHASE II ALTERNATIVES AND RECOMMENDATIONS VOLUME II -- CASE PLOTS Prepared for Alaska Power Authority Contract No. 2800122 PTI Project No. 30.2608 Prepared by: Harrison K. Clark POWER TECHNOLOGIES, INC. Roseville, CA March 30, 1989 PTI Report No. R35-89 READING PSS/E PLOTS The horizonal axis is the variable time in seconds in all cases in this report. The scale is .5 seconds per division in most cases (using a constant scale makes comparison of cases easier). The vertical axis varies, and may represent several variables on any given plot. The several variables, or the several similar variables from different stability cases or different pieces of equipment are detailed in the legend along the right side of the plot. The legend shows the scale limits. To get values for the 10 divisions, divide the total range from lower to upper limits, and work up from the horizontal axis. For instance, voltage is plotted from .3 to 1.3 per unit, so the divisions along the vertical axis represent 10% steps, starting at 30%. Note that the downward voltage excursions may look larger than actual because the vertical axis scale cuts off the lower 30%. Base values may be either machine base (e.g. for PMECH) or system base (e.g. for PE, generator electrical power). Per unit values can be multiplied by 100 to convert to percent. Voltage bases are 115 kV and 230 kV. Most generator rotor angles are plotted relative to ML&P unit number 7. That is, the angle that is plotted is the difference between the generator rotor angle of the identified machine and the ML&P #7 machine. This is used to show the angular swings on the Kenai peninsula relative to the Anchorage area. The channel labels in the legend are as follows: A = generator rotor angle in electrical degrees Vv = voltage in per unit of 115 or 230 kV E = bus frequency deviation from 60 Hz, in per unit of 60 Hz (multiply by 60 to get deviation in Hz) SP = generator rotor speed deviation from nominal in per unit of nominal rotor speed B = SVS admittance in per unit of 100 MVA system base (multiply by 100 to get MVAR) stabilizer output voltage in per unit (amount by which voltage regulator input voltage is biased) P = line real power in MW (from and to buses follow, P-DR-APT is from Diamond ridge to Anchor Point) ST Q = line reactive power in MVAR PE = generator terminal voltage, per unit PG = generator terminal power, per unit on 100 MVAR base QG = generator reactive power, per unit on 100 MVAR base PM = turbine power, per unit of generator MVA rating (e.g. 63 MVA for Bradley units). EF = Field voltage in per unit of no-load airgap Efd STABILITY CASE LIST The cases are listed below under the same headings used in the text report (Volume 1).

Like 157 but 18% (machine base) line/transformer drop compensation. Reduces downward voltage excursion during first swing, but also pushes up backswing overvoltages. SVS SIZE & DESIGN no cases LOAD REJECTION OVERVOLTAGES no cases BRAKE CONTROL 193 194 195 196 197 154 155 179 204 Like case 161 (fault, trip of Bradley to Soldotna line) except brake off 6 cycles early. Unstable. Like 193 except brake off at correct time (essentially identical to case 161). Like 194 except brake off 6 cycles late. Stable. Larger backswing overvoltages. Like 194 except brake off 12 cycles late. Stable. Trip of Bradley to Soldotna line without fault, brake on for .5 seconds (longer than necessary). Brake off too early, results in large oscillations that cannot be damped by stabilizers. Similar to 154. Case shows inadvertent brake application is not a threat and does not dictate brake size or timing. Similar to case 197. BRADLEY LAKE LIMITED TO 90 MW 200 Bradley Lake at 90 MW, no SVS, no SC, 40 MW brake, runback to 60 MW. Stable in all respects. Shows no line compensation required for 90 MW operation at Bradley. Stabilizers and brake and deflector control are required. SVS ALTERNATIVE 208 209 210 Fault and tip of line from Bradley to Soldoma with two SVS and no series capacitors. SVSs 45/-10 MVAR, no SVS stabilizers. Stable, very low backswing overvoltages. Similar to 208 except SVSs 35/0 MVAR and no SVS or Bradley Stabilizers. First-swing stable, low backswing overvoltages, negative damping (growing oscillations). Similar to 209 except with Bradley stabilizers operating. Stable in all respects. Shows two +35/0 MVAR SVS are adequate with runback to 90 MW and a 50 MW brake. 230 kV LINE ALTERNATIVE 167 Fault, trip Bradley to Soldotna line, reference case, stable. 198 Fault, trip 230 kV line. Unstable 198A Like 198 except brake applied. First-swing stable, shows negative damping. 199 Like 198A except detailed load models. Significantly less damping than case 198A. : 207 Like 198A except Bradley ramped back to 90 MW. Stable (though damping is poor).

APPENDIX RAILBELT STABILITY STUDY ANCHORAGE TO FAIRBANKS UPGRADE This study addresses an increase in power delivery from the Anchorage area to Fairbanks. Two alternative were considered, an increase from 70 to 100 MW measured at Douglas on the line to Cantwell and an increase from 85 to 115 MW measured at the Gold Hill end of the line from Nenana. Increasing 30 MW at Douglas provides only 22.6 MW at Gold Hill after losses. Increasing Fairbanks import by 30 MW at Gold Hill requires 42 MW at Douglas. The transmission upgrade options considered were: ° Increase SVS sizes (no series capacitors), ° Add series capacitors, ° A combination of SVS and series capacitor equipment. We did not look at new SVS locations, however, it appears that the existing locations would be adequate. A second transformer was assumed to be in place at both the Teeland and Gold Hill substations. The new transformers were assumed to be identical to the existing units. In the cases representing an additional 30 MW measured at Douglas (22.6 MW at Gold Hill), the Chena 5 generator is operating at 8 MW. It’s reactive output is near zero in the base case and does not change appreciably because the Gold Hill SVS effectively isolates it from the line reactive losses. Note however, that acceptable performance following loss of the Gold Hill transformer and SVS will require some Fairbanks area "spinning reactive reserve." In the cases representing an additional 30 MW measured at Gold Hill the Chena 5 generator is on-line at zero MW. The reactive output of the machine varies by only 2 or 3 MVAR in the cases. It is effectively off-line, and could have been so in these cases. In all cases with increased power flow to Fairbanks, loss of the Healy generator is the worst- case for setting the SVS capacity at the three SVS locations, and the series capacitor requirements when considered. This contrasts with the present day condition wherein loss of Chena 5 dictates the SVS capacity requirements at the three locations. Power Technologies, Inc. Page 2 While the results reported below appear to be based only on power flow cases, the SVS sizes do in fact include about 5 MVAR to cover dynamic system requirements. This increment is based on several simulations included in Appendix I. These simulations show that a margin of 5 to 10 MVAR over steady state requirements at each SVS site will meet first-swing and damping requirements. These cases did not include detailed motor models for the motor load, and may thus be somewhat optimistic. Simulations with detailed load models are recommended before compensation levels are finalized. Present System Upgrade The present system, operating at 70 MW (measured at Douglas), does not meet the criteria selected for the upgrade. The criteria requires the system to withstand 138 kV faults followed by loss of the Healy generator or loss of Chena 5. To meet the criteria at 70 MW, the following two additions are required: ° Douglas - Cantwell -- 70% series compensation ° Gold Hill SVS -- add 22 MVAR These additions are dictated by loss of Chena 5. Without these additions the loss of Chena 5 causes voltages to swing down to about 55% in the Fairbanks area, and return only to about 90% (without representing loss of load). However, in the following period (2 to 3 minutes after the fault) voltage collapse will occur as distribution LTCs and loads adjust to the low voltage. Even if some load is lost from the 55% voltage swing, it would eventually return to the system and eventually pull voltages down. There may also be line tripping from the low voltage, taking down part or all of the Fairbanks area. Without the series capacitors, approximately 122 MVAR of new SVS capacity would be required to meet the post-disturbance steady state requirement. Maximum Series Compensation -- Increased Transfer The case with maximum series capacitors has 70% series compensation in each of the six lines between Point MacKenzie and Gold Hill. In this scenario the Gold Hill SVS must be upgraded to a 55 MVAR upper limit (an addition of 22 MVAR) to support an additional 30 MW measured at Gold Hill. The additional SVS could be placed on the tertiary of the new Gold Hill transformer. If the power increase is to be 30 MW measured at Douglas, the Gold Hill SVS upgrade is the same, and the series capacitor between Nenana and Gold Hill is eliminated (Including this series capacitor does not appreciably reduce the Gold Hill SVS upgrade requirement). Power Technologies, Inc. Page 3 No Series Capacitors -- Increased Transfer Without series capacitors, the SVS upgrades to supply an additional 30 MW measured at Douglas (22.6 MW at Gold Hill), and meet criteria, the SVS additions are: ° Teeland -- add 51 MVAR ° Healy -- add 66 MVAR ° Gold Hill -- add 5 MVAR Without series capacitors, the SVS upgrades to supply an additional 30 MW at Gold Hill, and meet criteria are: ° Teeland -- add 87 MVAR ° Healy -- add 104 MVAR ° Gold Hill -- add 5 MVAR These sizes do not include a margin for dynamic requirements. Such SVS sizes would be very costly and would present very difficult control problems. It is presumed that an all SVS upgrade will not be considered further. Combination Series Capacitors and SVS A set of cases was run with a 70% series capacitor in the line from Douglas to Cantwell supplemented by additional SVS capacity to provide 30 MW additional transfer measured at Douglas. The SVS additions are: ° Teeland -- add 18 MVAR ° Healy -- add 28 MVAR ° Gold Hill -- add 22 MVAR A similar set of cases was not run with the transfer increased 30 MW measured at Gold Hill. Power Technologies, Inc. Page 4 Light Load Conditions Several cases were run to assess light load conditions and restoration problems. With loads reduced to zero north of Douglas, voltages rise to about 106% with the existing SVS underexcited limits and 70% series capacitors in six lines. Without the series capacitors the voltages are about 2% higher. These cases include some line charging from the Fairbanks area that presumably would not be connected when the load in Fairbanks is zero (i.e. during system restoration). These cases show that the existing underexcited limits on the SVSs are adequate and need not be changed. Also, the series capacitors improve control of light-load voltages. Outage of Gold Hill - Fort Wainwright line A case was run to show the real and reactive loading on the Gold Hill transformer during outage of the line from Gold Hill to Fort Wainwright. The case was run with just one transformer at Gold Hill. The transformer loading with an increase of 30 MW delivered at Gold Hill, and the line outage, is 123 MVA. Teeland 230-138 kV Transformer Loading A case was run to show the real and reactive loading on the Teeland transformer during outage of the Healy generator. The case was run with just one transformer at Teeland. The transformer loading with an increase of 30 MW delivered at Gold Hill, and the generator outage, is 151 MVA. Losses The losses are quite high for the additional transfers examined in this study. The incremental losses between Douglas and Gold Hill are 7.4 MW for delivering 22.6 MW at Gold Hill and 12 MW for delivering 30 MW at Gold Hill. The incremental losses are 33% and 40% respectively. The increase from 22.6 to 30 (7.4 MW) causes losses of 4.6 MW, or 62% incremental losses. Teeland and Gold Hill Transformer Additions Power flow cases were run to check the SVS size requirements without transformer additions at Gold Hill and Teeland. These cases were done with maximum use of series capacitors. Upgrade to provide the additional 30 MW import at Gold Hill included 70% series compensation in the six lines between Point Mackenzie and Gold Hill. Upgrade to provide the additional 30 MW measured at Douglas included 70% series compensation in the five lines between Point Mackenzie and Nenana. Power Technologies, Inc. Page 5 If the additional 30 MW is measured at Douglas, an increase in shunt reactive support from Teeland of approximately 15 MVAR will be required to maintain voltages following loss of the , Healy generator. Further analysis may show switched shunt capacitors to be adequate for this 15 MVAR. If the additional 30 MW is measured at Gold Hill, the base case loading in the Teeland 230- 138 kv transformer is 122 MVA. Therefore this import level wasn’t studied with one transformer at Teeland. There is a negligible effect on the Healy and Gold Hill SVS size requirements when comparing cases with one and two 138-69 KV transformers at Gold Hill. Greg Brownell Harrison K.
