INTRODUCTION Studies have been performed on the Transient Network Analyzer of General Electric's Electric Utility Systems Engineering Department in Schenectady, New York. The studies performed using the Analyzer were the _ load rejection, short circuit, TNA and control system studies as required by Contract No. APA-83-C-0051. Also included are the results from the speed of response tests to satisfy paragraph 2.10 of Section 6.3.1 of the specification. Reports of these individual studies have been combined to form this report. In this study, the Pt. Mackenzie transmission area was represented as 138 kV. As required in each case, a model of a strong or a weak Pt. Mackenzie 138 kV equivalent was used. This study complements the first study, where Pt. Mackenzie transmission area was represented as 230 kV. Those cases which were not affected by the Pt. Mackenzie transmission area representation were not repeated in this study. 2. CONCLUSIONS For the conditions studied and excluding the Cantwell to Watana line: a. The SVS operated effectively to control the dynamic and temporary overvoltages that follow load rejection. However, load rejection at the Gold Hill 138 kV, with the Healy generator and SVS off, resulted in high temporary overvoltages. b. The SVS operated effectively to restore system voltage following system faults. Gs d. £. The application of special zinc oxide arresters in parallel with the SVS thyristor controlled reactors at Teeland, Healy and Gold Hill is required to limit the voltage across the thyristors. The arresters would have a temporary power frequency overvoltage capability similar to that given in Figure 1 of GET-6460, General Electric TRANQUELL® Station Surge Arrester Application Guide. The switching surge duty on the Intertie line and transformer arresters was found to be within their capabilities. Speed of response tests were. performed to show the capability of the SVS to go from full lag to full lead in 3 cycles and from full lead to full lag within a consecutive 3 cycles. Results of the control study showed stable system operation with SVS time constant of 150 ms. Cantwell-Watana Line In Service gS. Healy SVS operates at the limit of its control range, following load rejection at Gold Hill 138 kV. 3. BASIS OF STUDY a. System Representation The Intertie was modeled in detail using miniature model techniques from the Pt. Mackenzie 138 kV bus to the Gold Hill 69 kV bus where inductive equivalent impedances were used to represent the Anchorage and Fairbanks systems. In all cases, the Gold Hill 69 kV equivalent was for the minimum generation condition. The Pt. Mackenzie 138 kV equivalent was represented either as a weak equivalent or as a strong equivalent. 138 kV submarine cables from Pt. Mackenzie to Pt. Woronzof were modeled as an equivalent capacitor bank at Pt. Mackenzie 138 kV bus. The data for the system was derived from the specification and from several letters from Commonwealth Associates. The system diagram is shown in Figure A-l of Appendix A, on page A-5. The parameters for the lines and transformers are shown in Appendix D. b. SVS Models All three SVS's were modeled with a high degree of detail. Actual SVS electronic controls were used to control the firing of the thyristors of the controlled reactors. These controls were implemented on the TNA by the HVDC Projects Operation of General Electric in King of Prussia, Pennsylvania, the responsible product section for SVS. The power thyristors, reactors and filter banks were modeled with miniature model elements. In general, unless otherwise noted, the gain of all three SVS's were set to 20 (full range of MVAR change for a 5% voltage change) and with reference setpoints as indicated. Associated Voltage Control ee Reference Range Voltage Location Setpoint (pu) (pu) Teeland =e to Bon T.00 -975 to 1.025 Healy -33 to +22 1.02 1.00 to 1.05 Gold Hill -5 to 33 1.02 ~9/5 ito 12025 (It is not intended to imply that the reference setpoints used in service must be identical to the values shown.) Also, unless otherwise indicated, the time constants for all SVS's were set at 150 ms. Cs Thyristor Voltage Limitation and Thyristor Controlled Reactor Arresters The TNA cases presented in this report are based on the application of special zinc oxide arresters connected line-to-line in parallel with the thyristor controlled reactors of the Teeland and Healy SVS. The TCR arresters limit the voltage to approximately 31 kV which is 1.59 pu for Teeland and 1.83 pu for Healy. These arresters will consist of a number of parallel columns of zinc oxide disks. The number of parallel columns required is dependent upon the discharge duty encountered during system disturbances. The duty requirements are defined further in the case discussion. Following the results of filter energization at Healy SVS, ‘application of zine oxide arresters were also recommended at Gold Hill TCR in order to limit the overvoltages during filter energization. Possibility of the restrike of the SVS breaker could result in substantial TCR arrester discharge. All TCR arresters, at all three locations, have been rated to withstand such a restrike. The final TCR arrester designs are as follows: Switching Surge TCR Arrester No. Of Energy Capability Location kV_Rating Columns MW-Sec. Teeland 16.1 5 -467 Healy 16.3 6 Loe L Gold Hill 16.5 8 743 The voltage-current characteristic used to model the Healy TCR arresters in this study was higher in voltage than that used in the first study, more closely representing the final arrester design. This higher characteristic resulted in lower arrester energy absorption during system switching events. d. 138 kV Intertie Line and Transformer Arresters As a simplifying assumption, all arresters applied to the 138 kV Intertie line sections and transformers were modeled with a 108 kV rating for convenience, even though some are rated 120 kV on the actual system. The results are, therefore, slightly pessimistic for the 120 kV arresters which would absorb less energy than the TNA predicts. This fact does not change the overall conclusions. e. Load Modeling The loads on the Intertie (at Teeland, Douglas, Cantwell, Watana, Healy and Nenana) were assumed out of service. The overvoltages found are, therefore, slightly higher than actual. It was presumed that there is no significant temporary ''backfeeding'' from the load that can occur when the associated 138 kV line section is isolated from the rest of the system. Such backfeeding could result in high overvoltages if breaker relaying allows large motors to remain connected to an isolated line section. 4. DISCUSSION OF CASES The cases have been divided up into five categories: a. load rejection, b. fault initiation and clearing, c. line energizing, d. speed of response and e. control study. The requirements of short circuit study of the specification have been fulfilled in category b. The individual case descriptions and oscillograms of selected voltages and currents are contained in Appendix A. =5< a. Load Rejection Load rejection cases were performed with the Gold Hill - Ft. Wainwright line in service and Healy generator and transformer out of service. The Cantwell-Watana line was in service only in Case 402. In all cases, there was approximately 70 MW of power flow from Anchorage to Fairbanks. The summary of the results is presented in Table 1. Listed in Table 2, are the three phase rms voltage measurements at various locations and under a variety of open breaker combinations. Case 400 In this case, the strong equivalent representation of the Pt. Mackenzie area was used. The opening breaker was the 138 kV breaker at Gold Hill, on the Gold Hill-Nenana line (Breaker Q). After opening the breaker, the maximum temporary power frequency overvoltage was 1.08 pu at the open end of the Gold Hill-Nenana _ line. The SVS maintained temporary overvoltage control. The arrester duty at the open end of the Gold Hill-Nenana line was 0.02 MW-sec. Healy TCR arrester duty was 0.03 MW-sec. Case 401 This case was the same as Case 400, except the weak equivalent representation of the Pt. Mackenzie was utilized. Results were very similar to those discussed in Case 400. The arrester duty at the open end of the Gold Hill-Nenana line was 0.05 MW-sec. Healy TCR arrester duty was low. Case 402 Case 401 was repeated after Cantwell-Watana line was put in service. After opening the breaker, the maximum temporary power frequency overvoltage was 1.10 pu at the open end of the Gold Hill-Nenana line. The Healy SVS was operated at the limit of its control range. The arrester duty at the open end of the Gold Hill-Nenana line was 0.06 MW-sec. Healy TCR arrester duty was again low. Case 403 The strong equivalent representation of the Pt. Mackenzie area was used. The opening breaker was the 138 kV breaker at Gold Hill, on the Gold Hill-Nenana line. After opening the breaker, the maximum temporary power frequency overvoltage was 1.09 pu at the open end of the Gold Hill-Nenana line. The arrester duty at open end of the Gold Hill-Nenana line was 0.06 MW-sec. Healy TCR arrester duty was 0.01 MW-sec. Case 404 Case 401 was repeated with Healy SVS out of service. After opening the breaker, the maximum temporary power frequency overvoltage was 1.5 pu, at the open end of the Gold Hill-Nenana line. Based on Figure 1 of GET-6460 General Electric TRANQUELL 108 kV arrester, this temporary overvoltage has a Station Surge Arrester Application Guide, for a permissible duration of 90 seconds. Nevertheless, since the actual arrester rating at this location is 120 kV, the permissible duration is approximately 30 minutes. Case 405 Weak equivalent representation of the Pt. Mackenzie area was used. The opening breaker was the 138 kV breaker at Healy on the Healy-Nenana line (Breaker J). After opening the breaker, the maximum temporary power frequency overvoltage was 1.02 pu at Cantwell 138 kV bus. The arrester duty at Healy-Douglas line entrance was 0.01 MW-sec. Healy TCR arrester duty was low. bs Fault Initiation and Clearing In all the cases studied, the Healy generator and transformer were out of service. Except for Case 501, the weak equivalent representation of the Pt. Mackenzie area was used. The Cantwell-Watana line was in service for Case 503 only. In addition, approximately 70 MW of power flow was simulated from Anchorage to Fairbanks. The summary of the results is presented in Table 3. Case 500 In this case, Cantwell-Watana line as well as Ft. Wainwright-Gold Hill line were out of service. A _ single line-to-ground fault was simulated on the 138 kV bus at Gold Hill. The 138 kV breaker at Gold Hill on the _ Gold Hill-Nenana line (Breaker Q) was opened in approximately 4 cycles and the 69 kV Gold Hill breaker (Breaker Z) was opened in 6 cycles. The fault initiation angle was varied statistically 50 times and the duty to the arresters at the open end of the Gold Hill-Nenana line was recorded. The maximum energy per phase was 0.13 MW-sec. The attached case sheets contain numerous oscillograms of voltages at various locations of interest. Also included are, oscillograms of the total fault current, fault current contributions from Nenana and from Gold Hill transformer and the TCR currents. The maximum transient overvoltage on the Intertie line is 1.6 pu at Gold Hill end of the Gold Hill-Nenana line. The Teeland and Healy SVS operated appropriately to control the 60 Hz voltage. Case 501 The strong equivalent representation of the Pt. Mackenzie area was used in this case. The Cantwell-Watana line was out of service, while the Gold Hill-Ft. Wainwright line was in service. A single line-to-ground fault was simulated on the 138 kV bus at Healy. This fault initiation was followed by opening the 138 kV breaker at Healy on the Healy-Nenana line (Breaker J) in 4 cycles and opening of the 138 kV breaker at Healy on the Healy-Cantwell line (Breaker I) in 6 cycles. The maximum energy per phase for the arrester at the Healy end of the line from Cantwell was 0.08 MW-sec. The maximum transient overvoltage of 1.8 pu was recorded also at the Healy end of the line from Cantwell. The Healy TCR arrester duty for this case was 0.06 MW-sec. Case 502 Case 501 was repeated with the weak equivalent representation of the Pt. Mackenzie area. The maximum energy per phase for the arrester at the Healy end of the line from Cantwell was 0.11 MW-sec. In general, results were very similar to those in Case 501. Case 503 This was the repeat of Case 502 after Cantwell-Watana line was put in service. Again, results were similar to the previous two cases. The maximum energy per phase for the arrester at Healy end of the line from Cantwell was 0.12 MW-sec. Case 504 In this case a single line-to-ground fault at Teeland 138 kV bus was simulated with Cantwell-Watana line out of service and Gold Hill-Ft. Wainwright line in service. The fault was cleared in 6 cycles by opening the 138 kV breakers at Teeland 138 kV bus (Breakers B and M). The maximum transient overvoltage on the Intertie line was 1.6 pu at Teeland end of line from Douglas. The line arrester duty at that location was 0.11 MW-sec. The TCR arrester duties at Healy and Teeland were low. Healy and Gold Hill SVS provided the proper power frequency voltage control. Case 505 Gold Hill-Ft. Wainwright line was taken out of service and Case 504 was repeated. The maximum energy per phase for the arrester at Teeland end of line from Douglas was 0.20 MW-sec. The TCR arrester duties at Healy and Teeland were low again. Case 506 A single line-to-ground fault was applied on Pt. Mackenzie 138 kV bus, with Gold Hill-Ft. Wainwright line in service and Cantwell-Watana out of service. Fault initiation was followed by opening the 138 kV breaker at Pt. Mackenzie on the Pt. Mackenzie-Teeland line (Breaker A) in 4 cycles. The maximum energy per phase at Teeland TCR arrester was 0.11 MW-sec. The arrester duties at 138 kV intertie line and Healy TCR were low. =10= Case 506A This case repeated the previous case (Case 506) after the Gold Hill-Ft. Wainwright line was taken out of service. The maximum energy per phase at Teeland TCR arrester was 0.09 MW-sec. Oscillograms showed no significant difference between this case and Case 506. Case 507 A three phase to ground fault was simulated at the 138 kV Gold Hill bus. The 138 kV breaker at Gold Hill on the line to Nenana (Breaker Q) was opened in 4 cycles. The 69 kV Gold Hill breakers (Breaker B) opened in 6 cycles. There were no significant energy to the Healy TCR arresters as well as the line arresters at Gold Hill on the line from Nenana. Teeland and Healy TCR currents exhibited no dc offset, as was indicated in Case 205 of the first study. Cis Line Energizing The energizing cases were performed with a model breaker whose closing angles were computer controlled to fall within the desired closing span of 8.33 milliseconds in a statistical manner. When an open line was being energized, a distribution of the overvoltages at the end of that line was recorded with no line arresters present. If the highest overvoltage event exceeded the line arrester voltage protection level, a model arrester was placed at the line end and its maximum energy requirements were investigated. However, an important comment must be made with regard to the above procedure. In cases where a line or capacitor and a transformer are being switched as a unit, the TNA results can be non-repeatable due to the unpredictable residual flux levels in the iron of the transformer. It is, =l1= therefore, difficult to capture the precise waveform that the random distribution found to be the maximum. In any event, the maximum energy found in the random distribution is taken to be a measure of the maximum arrester duty. In all cases, Cantwell-Watana line was out of service. The strong Pt. Mackenzie area equivalent was used only in Case 600. The summary of the results is presented in Table 4. Case 600 In this case, the Douglas-Healy line was energized from Douglas with Healy SVS out of _ service. The strong representation of the Pt. Mackenzie area equivalent was used. The maximum transient overvoltage at Healy end of the energized line was 2.77 pu. Maximum arrester energy at this location was 0.06 MW-sec. There were no arrester operations at Teeland TCR. Oscillograms shown in the case sheets were recorded with the line-end arresters applied. Case 601 Case 600 was repeated with the weak Pt. Mackenzie area equivalent. Maximum transient overvoltage at Healy end of the line was 2.69 pu. Maximum line-end arrester duties were 0.05 MW-sec. Case 601A Case 601 was repeated with the Teeland SVS out of service. The following results were recorded at the Healy end of the energized line: =1 96 Maximum temporary 60 Hz overvoltage of 1.17 pu. Maximum transient overvoltage of 2.44 pu. Maximum 108 kV arrester duty of 0.06 MW-sec. Case 602 In this case, Douglas-Healy line together with Healy SVS transformer were energized from Douglas. Healy SVS was not connected. The maximum transient overvoltage at Healy end of line was 2.37 pu. There, the maximum arrester energy was 0.07 MW-sec. Case 603 This case was similar to Case 602, except here Healy SVS was in_ service. The Douglas-Healy line, Healy SVS transformer and Healy SVS were all energized in one operation. The effect of the status of the actual TCR gate energy prior to energization was not investigated. Maximum transient overvoltage and maximum arrester duty at Healy end of the line were 2.49 pu and 0.08 MW-sec, respectively. Healy TCR arrester energy recorded was 0.11 MW-sec. Case 604 In this case, the Healy SVS transformer was energized from Healy end of line from Douglas with Healy SVS out of service. Maximum transient voltage at Healy SVS _ transformer. Primary was 1.70 pu. Cases 605, 606 - Ramp up Healy TCR and Energize Filters These two cases were performed in order to exhibit the startup performance of the SVS at Healy. In both cases, Healy SVS transformer was connected to the Healy end (open end) of the line from Douglas. == The procedure for performing each case was as follows: first, with the filter bank switched off, the Healy TCRs were ramped up to approximately 22 MVAR. Then, the filter bank was switched on (energized). Oscillograms showing the voltages and TCR currents during and after the completion of this procedure are included for further clarification. The voltage distortion during the Healy SVS ramp up is less at Teeland, if the Teeland SVS is in service. A random distribution of the overvoltages at Healy 12 kV bus were taken for the filter bank energizing using a closing span of 360 degrees for the filter bank switch. In Case 605, where Teeland SVS was in service, the maximum transient overvoltage at Healy 12 kV bus was 2.19 pu. Healy TCR arrester duty for this case was 0.04 MW-sec. In Case 606, where Teeland SVS was not in service, the maximum transient overvoltage at the Healy 12 kV bus was 2.29 pu. Healy TCR arrester duty for this case was 0.01 MW-sec. Case 650 The Healy-Douglas line was energized from Healy with Healy SVS operating from the Healy 138 kV bus. The Gold Hill-Ft. Wainwright line was out of service. The maximum transient overvoltage at Douglas end of the energized line was 2.60 pu. There, the maximum arrester duty was 0.05 MW-sec. Case 651 This case was the repeat of Case 650 after Gold Hill SVS was taken out of service. This change in the system did not prove to be significant and the results obtained were effectively the same as those in Case 650. ee d. Speed of Response These cases were performed in order to show the capability of each SVS to go from full lag to full lead in 3 cycles and from full lead to full lag within a consecutive 3 cycle time period. Two sets of results corresponding to SVS voltage regulator lag time constants of 150 ms and 88 ms were documented. Case SVS1 With Cantwell-Healy line opened at Cantwell end, a three-phase fault was applied at the Cantwell end of the line from Watana. This fault was cleared in 3 cycles by opening the Cantwell-Watana line. The oscillograms show the speed of response of the Teeland SVS. Case SVS2 The Healy SVS's speed of response was tested using the three-phase fault at Cantwell end of the line from Watana again. The Cantwell-Douglas line was opened at Cantwell end, and the Ft. Wainwright-Gold Hill line was out of service. svs3 In order to investigate the speed of response at the Gold Hill SVS, a three-phase fault was placed at the Gold Hill end of the line from Nenana, with Nenana end of the line open. This fault was cleared in 3 cycles by opening the 138 kV breaker at Gold Hill. e. Control Study The purpose of this study was to investigate the range of SVS time constants for which stable or unstable operation of SVS would result. -15- The circuit condition studied was load rejection at the Teeland 138 kV via opening the 138 kV breaker on _ the Teeland-Pt. Mackenzie line. The Cantwell-Watana, Healy generation and transformer and the Gold Hill-Ft. Wainwright line were all out of service. There was approximately 70 MW of power flow from Anchorage to Fairbanks. The first control study for the power system with the 230 kV Pt. Mackenzie transmission area had shown that the condition with the Teeland 230 kV breaker open was decisive for the SVS regulator time constant. For the 138 kV Pt. Mackenzie transmission area conditions, the opening of the Teeland 138 kV breaker on the Teeland-Pt. Mackenzie line produces a similar decisive condition for the SVS regulator time constant. As shown by the oscillograms, unstable operation of the Teeland SVS results when its time constant is reduced from 150 ms to 53 ms. This test confirmed that the 150 ms time constant was appropriate. -16- APPENDIX A Index to Cases Test Result Sheets I-¥ Table 1. Load Rejection Max imum Post-Swi tch SVS Maximum Arrester Duties Pt.

The first page shows the circuit diagram for that portion of the system studied. Circuit breakers and switches are indicated by lettered squares; system locations which were monitored are identified by numbered circles. The system operation is defined and the results are summarized therein. The second page tabulates the system voltages recorded for the various system conditions as identified in the table headings. They include both the temporary pre-switch and post-switch voltages. The succeeding pages display the statistical distribution curves of the transient voltages and/or the oscillograms of the voltage, current and/or energy waveforms taken during the test. The following is a description of the various lines and column headings in the order of their occurrence. FIRST PAGE - UPPER HALF DIAGRAM - The upper half shows a one-line diagram for that portion of the system being investigated. FIRST PAGE - LOWER LEFT QUARTER CASE NO. - The number of each case appears in this space. B-1 OPERATION Pre-Switch Post-Switch Sustained Fault Energizing Energizing into a Fault De-Energizing The following nomenclature is used. The voltages on the system before the circuit breaker operates, and no fault on the system. The voltages on the system after the circuit breaker operates and after all transients have subsided. The voltages on the system with the operating circuit breaker closed and with a fault on the system; all transients have subsided. Energization of a portion of the system; no trapped charge present. Energizing a portion of the system with a bolted fault present; no trapped charge exists on the system. Investigation of transients incurred when switching off (isolating) a portion of the system without current-chopping by the operating circuit breaker. B-2 Load Rejection Restrike Fault Initiation Fault Clearing Fault Initiation and Clearing FROM TO With a specified load flow all three poles of the line breaker are opened. The interruption of load flow of this investigation does not include any reaction due to machine overspeed and/or any excitation system response. A single or multiple phase restrike across the opening contacts of the breaker during a de-energizing operation. Investigation of the transients when a fault occurs. Three phase de-energization of a portion of the system suffering from a fault. A fault is initiated and subse- quently de-energized by opening of the appropriate circuit breakers. Station bus at which the switching is performed. Location of the remote (receiving) end of the line, cable, transformer or other terminal apparatus being switched.

The parameters of the operating breaker or switch are then listed as follows: CLOSING RESISTOR, OPENING RESISTOR INSERTION TIME MAXIMUM CLOSING SPAN, OPENING SPAN The ohmic value of the resistor inserted in the closing or opening sequence. Minimum time that the resistor is inserted. Maximum possible pole misalign- ment during the closing or opening operation. RESULTS - The magnitude of the highest voltage observed during this particular investigation is recorded here. The existing and applicable arrester ratings, types and constructions at the indicated locations are specified herein. CONCLUSIONS - Any other pertinent information or conclusions appear here. SUBSEQUENT PAGES The following pages may display the tabulated system voltages for various system conditions, the statistical distribution curves of the transient voltages, and the oscillograms of the voltage, current and energy waveforms pertaining as required by the specific case. B-5 APPENDIX C Surge Arrester Types and Protective Characteristics The three types of surge arresters considered in a TNA study are: Type 1. General Electric Alugard (R) I Arrester_ or Equivalent 1; 312 kV and below (Model 9L11L) a. The arresters can sustain 1.10 x rating for 10 cycles. b. The voltage impressed on the arrester must not exceed rating for more than 20 cycles. 2. 336 through 444 kV (Model 9L16A) a. The arrester can sustain: 1.3 x rating for 5 cycles, or 1.25 x rating for 10 cycles. b. The voltage should drop to 1.1 x rating within 20 cycles. Type 1 arresters are essentially obsolete and _ the manufacturer should be consulted for more specific capabilities. Type 2. General Electric Alugard (R) II Arrester_ or Equivalent Ls All ratings (Model 9L11M or 9L16B) can sustain: a. One-half cycle at 2.0 x rating followed by an envelope of 1.3 x rating of 10 cycles, followed by 1.2 x rating for the next 10 cycles and 1.15 x rating for the next 40 cycles (1 second total on a 60 Hz basis). b. Two one-half cycles at 1.6 x rating followed by an envelope of 1.25 x rating at 10 cycles, 1.2 x rating for the next 10 cycles and 1.15 x rating for the next 40 cycles (1 second total on a 60 Hz basis). C-1 Type 3. General Electric Tranquell (R) or Equivalent This type of arrester is constructed from disks of metal-oxide which act as a highly nonlinear resistor to limit the overvoltages at locations to be protected. The arrester may be gapless or be equipped with either a series or shunt gap. The manufacturer of the arrester should be consulted for specific application rules regarding gapped arresters. In general, metal-oxide arresters have a maximum continuous operating voltage (MCOV) which corresponds to the maximum RMS voltage that may be impressed on the arrester continuously. This type of arrester can be damaged if the temperature of the metal-oxide is changed too rapidly or exceeds approximately 180 degrees Celsius. Since the temperature is directly related to the energy dissipated by the arrester, application rules are generally given in terms of a normalized energy density such as MW sec/kV of rating. The energy densities associated with standard Tranquell station class arresters are given in Table C-l. In addition, applicability of such arresters in temporary overvoltage situations is given by voltage-time curves which may be obtained from the manufacturer. Table C-1 Table of Tranquell Arrester Energy Absorption Capability Arrester Maximum Energy Ratings (kV) Capability (MW sec/kV) 2.7-48 -004 54-360 -0072 396-588 -0132 c-2 The design of gapless metal-oxide arresters is very flexible in that matched multiple columns may be applied in situations where the dissipated energy is very high. In certain circumstances they may also be operated above MCOV if special cooling can be provided. Arrester Protective Characteristics The protective characteristics of series gapped, silicon-carbide arresters are given in the test and application guides published by the American National Standards Institute. The standards suitable for arrester application are ANSI C62.1-1981 and ANSI C62.2-1981. The protective characteristics of metal-oxide arresters have not been tabulated in the ANSI standards. The manufacturer of these arresters should be consulted for such characteristics as are given in Table C-2 for General Electric Tranquell station class arresters. c-3 able C-2 Tranqueil Arrester Characteristics a) (2) (3) (4) (5) MAXUM MAXIMUM MAXIMUM CONTINUGUS EQUIVALENT MAXIMUM DISCHARGE VOLTAGE (kV CREST) SWITCHING VOLTAGE | FRONT-OF-WAVE | AT INDICATED IMPULSE CURRENT USING SURGE ARRESTER | CAPALILITY | PROTECTIVE AN & x 20 MICROSECOND CURRENT WAVE PROTECTIVE RATING oN) LEVEL LEVEL kV RMS kV RMS. kV CREST OkA ISkA |10kKA 115 kA kV CREST 27 2.20 8.1 : 64| 67] 7.2: 7.9] 85] 1023 5.6 3.0 2.54 9.3 69] 7.3] 7.7] 62! 90] 97] 11.7 6.4 45 3.70 13.5 - 10.0} 105] 11.0] 119] 128] 138] 164 92 5A 4.20 15.2 11.3] 118] 125] 134, 145] 155] 184 10.4 6.0 5.08 18.4 136] 144] $5.0] 161] 17.4) 186] 22.0] 12.6 75 6.10 22.1 16.4] 17.2] 12.0] 193] 209| 224] 265 15.1 85 6.90 25.0 185/ 195] 204] 21.8| 236] 25.2] 25.7 17.9 9.0 7.62 27.6 20.4) 21.5) 225) 24.0; 26.0] 27.7) 32.7! 188 10 8.47 30.6 22.7] 23.9] 249) 26.7) zee; 307] 361 20.9 12 10.16 36.7 27.2] 28.6] 299] 329! 2.5] 36.9] 43.4) 25.0 15 12.70 45.9 34.0} 35.7] 37.3} 395! 430) 459] 539 31.3 18 15.24 55.1 40.7) 428) 44.7] 478! 515; S49] 65.4 75 21 74 61.8 457| 480! coz} 38] 578! ss! 721 42.1 246 19.5 705 S21] 548/ 57.2] 21.2] 659] 703) S24 £8.0 27 21.9 79.1 585] 615| 64.3] €86/ 740; 789] 92.3 53.9 30 24.4 88.2 65.2) 685! 71.5] 764] 82.3) 87.7] 1025 0.1 36 29.3 106 78.2] 82.3) 85.9} 91.7! $8.7} 105 | 123 72.1 33 31.7 ns 84.5! €9.0] 92.9] $9.2! 107 | 114 | 122 78.0 45 36.5 132 97.4] 102 | 107 | 114 | 323 | 131 | 187 | 69.8 48 35.9 141 103.8] 109 | 114 | 122 | 121 | 130 | 10 95.7 54 43.7 142 105 | 110 | 115 | 122 | 129 | 135 | 157 106 60 43.6 158 117 | 123 | 128 | 136 | 144 | 150 | 174 118 66 535 174 128 | 135 | 141 | 150 | 158 | 168 | 192 130 72 53.3 183 140 | 147 | 153 | 163 | 172 | 180 | 209 142 80 72.9 237 175 | 184 | 192 | 204 | 215 | 225 | 261 177 96 776 253 187 | 196 | 204 | 218 | 230 | 281 | 27 189 108 875 284 210 | 220 | 230 | 245 | 258 | 271 | 313 213 120 97.2 315 233 | 245 | 255 | 272 | 287 | 300 | 348 236 132 105 347 256 | 269 | 281 | 2 316 | 331 | 383 250 144 110 380 280 | 295 | 307 | 327 | 345 | S62 | 419 234 168 119 441 326 | 342 | 357 | 380 | 01 | 420 | 487 331 172 139 451 333 | 350 | 365 | 389 | 410 | 420 | 493 338 180 146 474 350 | 368 | 383 | 40s | 431 | 451 | 523 355 192 152 506 374 | 393 | 410 | 436 | 460 | 482 | 555 379 228 164 600 443 | 465 | 486 | 517 | 545 | 572 | 662 449 240 71 629 465 | 488 | 509 | 542 | 572 | Sco | 694 471 258 208 678 500 | 526 | 549 | 584 | 616 | 646 | 748 508 264 214 694 512 | 539 | 562 | §s8 | 631 | 661 | 766 520 276 224 726 536 | 564 | 588 | 626 | 660 | 692 | 801 544 288 228 756 558 | 586 | 612 | 651 | 687 | 720 | 834 566 294 232 772 570 | 599 | 625 | 665 | 702 | 735 | B52 578 300 26 788 582 | 611 | 638 | 679 | 716 | 751 | 869 590 312 236 820 606 | 637 | 664 | 707 | 746 | 782 | 905 615 - 3001S)* 243 788 582 | 611 | 638 | 679 | 716 | 751 | S09 590 31218)" 253 820 6c6 | 637 | 664 | 707 | 745 | 732 | COS 615 3236 265 882 651 | esa | 714 | 760 | G02 | Bs0 | 973 651 360 275 47 699 | 735 | 766 | B16 | 861 | G2 {1045 709 396 321 1078 782 | 1B | s49 | 897 | 20 | 955 | ORS 779 1420 340 1142 629 | 857 | e799 | 950 | 985 {1012 | aI119 825 444 350 1209 877 | 917 | 952 ]1006 | 1043 J¥071 fates B74 688 476 1645 Wer f1215 [1261 | 13N | 1280 1418 | 4557 | 1197 males J are ple aes 300 and 312 kV ratings for 400 AV system application designated by BLTIFHS Or OLITRHS_ __ movel numbers, WOONDUNHWHH oe APPENDIX D System Parameters Equivalent Source Impedances Transmission Lines Transformer Parameters Thyristor Controlled Reactors Filters Arresters Load Flows Considered Breakers Svc D-1 1.

To predict and describe the nature of transient and harmonic overvoltages which can occur for any realistic switching operation. II. To seek out any abnormal duties imposed upon equipment by such switching operations. III. To devise solutions within the capabilities of equipment by: A. Exploring the influence of various system or apparatus design alternates. B. Establishing acceptable operating procedures. IV. To provide this information in a form suitable for use in: A. Establishing the insulation requirements of transmission lines. B. Establishing the data for insulation coordination; e.g-., BIL, SIL. Typical System Phenomena Which Can be Investigated on the TNA Les The occurrence and magnitude of system overvoltages have a direct bearing on the electrical design of a transmission system. A few of the more important causes of overvoltages, the magnitude and severity of which can be established by a TNA study are: E-1 A. Transient overvoltages caused by: L. Normal energization of uncharged transmission lines with or without connected transformers. Transient voltages will be produced in each phase as it is energized and by coupling as the other phases are energized. The zero sequence impedance may be a predominant factor governing the transient overvoltages occurring during the energization of a _ transformer terminated line. In cases of arrester protected cables and cable terminals, energization transient causing surge arrester operation may produce severe current discharges through the surge arrester. On many systems, the thermal limit of the surge arrester may be a critical factor in the system design. Energization of particular line/transformer combinations may also cause overvoltages lasting many cycles due to the nonlinear characteristics of the transformers. Harmonics generated by the magnetizing characteristics of the transformers interact with the parameters of the system (line capacitance and system inductances) and cause in-rush and nonlinear oscillations. In some instances, these oscillations may be sustained. Since these types of transient overvoltages persist for a relatively long time duration, they may impose overly severe duties on the surge arrester; hence, they are important factors in the specification of terminal equipment such as transformers. Operations which may lead to such nonlinear oscillations are: E-2 a. Energization of an autotransformer and a high voltage transmission line from the circuit breaker on the low voltage side of the step-up transformer, and b. Energization of a high voltage transmission line which is terminated with a transformer. High speed reclosing of a high voltage circuit breaker onto a transmission line which has retained a charge from a previous de-energizing operation by circuit breakers at each end of the line. If inductive shunt devices such as transformers, shunt reactors, or potential transformers are connected to the transmission line, the trapped charge will either be completely dissipated during the interval that the circuit breakers are open, or an oscillating charge of less than one per unit will exist at the time of reclosure. In general, therefore, the most severe transient overvoltages imposed on line insulation will occur when an open-ended line is reclosed. Restriking across the opening contacts of a circuit breaker during a de-energizing operation. Since restriking is similar to reclosing, restriking will cause transient overvoltages in the same order of magnitude as reclosing. Most modern’ oilless circuit breakers for transmission lines are designed so that they will not produce severe overvoltages if a restrike occurs. II. III. 4. The sudden disconnection of a _ generating station and its associated lines, cables, and/or transformers from the rest of the system (load), causing the terminal voltage to rise abruptly. Also, the machine speed and voltage will undergo transient variations, the magnitude and duration of which are functions of various parameters, such as number of machines and_ loading, line and/or cable remaining connected, excitation system performance, and transformer saturation. The resulting temporary overvoltages must’ be maintained below surge arrester reseal. 5. Switching capacitive kVA (capacitive banks or cable) causing magnification in some remote part of the connected low voltage system. B. Temporary overvoltages caused by: Ls A transmission line or cable’ remaining energized by a generating station or through a transformer, resulting in: a. Voltage rise along the line or cable (Farranti effect). b. Voltage rise through the source reactance. The TNA can also be used to study the effects of in-rush current characteristics when energizing lines and transformers. In general, these transients or dynamic overvoltages can be modified by various means. The TNA can be used IV. to study the effectiveness of the following means of modifying overvoltages: A. Surge arresters. B. Shunt reactors. C. Intermediate switching stations. D. Transfer trip relay schemes. E. Transformer tertiary design. F. Circuit breaker design - that is, resistor pre-insertion schemes and control of relative pole closing span. G. Static var systems. Results of TNA studies can form the basis for defining: A. Switching arrangements (high side vs. low side switching). B. Ratings and locations of arresters. C. Apparatus BIL requirements. D. Size and location of reactors. E. Advisability of furnishing tertiaries on terminal transformers. F. Approximate statistical switching surge data for transmission tower electrical design studies. G. Relay settings from standpoint of in-rush currents. General Classifications of Overvoltages I. Transient Overvoltages Depending upon system parameters, the point upon the source sine wave at which the operating circuit breaker operates and the relative position and sequence of operation of the individual poles of the operating circuit breaker, the transient voltages that might be E-5 encountered at a particular location due to a system switching operation can, in general, be classified according to wave shapes as defined below: A. Maximum Transient The transient voltage wave with the highest possible transient voltage crest after circuit breaker operation is referred to as the Maximum Transient. B. Maximum Surge Arrester Transient 1. Silicon-Carbide, Series Gap Arresters This type of transient voltage is characterized by the first or second voltage crest after circuit breaker operation being sufficiently high (but not necessarily the maximum value possible) that it might cause an operation of the surge arrester being considered for the location being investigated and one or more successive voltage crests above the reseal rating of the arrester before the arrester operates. If any subsequent transient voltage crests (after modification by the operation of the arrester) are above the reseal rating of the arrester, the arrester probably will be subject to multiple operations and _ possible failure. 2. Metal-Oxide Arresters The maximum surge arrester transient is characterized by the highest energy dissipation in the arrester. II. Temporary Overvoltages In addition to the transient overvoltages described above, systems may also be subject to longer term E-6 overvoltages caused by faults on the system or by load rejection. System Representation The system to be studied is represented in miniature on the Transient Network Analyzer (TNA). The TNA is a three-phase analog device used for real time simulation of the power system. Power for the model is supplied from a three-phase low impedance sine wave generator, which appears as an infinite bus to the miniature systen. System equivalents are represented by equivalent linear reactances connected to an infinite bus, in the positive, negative, and zero sequence systems. Nonlinear, low loss shunt or tertiary reactors are modeled with an electronic circuit which exhibits’ the correct terminal behavior. The inductance below and above saturation, the level of saturation, and the quality factor (Q) of these model reactors can be set to desired values. Transmission lines and cables under study are represented by three-phase, L-section equivalents composed of series resistance and inductance, and shunt capacitors connected to simulate positive and zero sequence susceptance of the line. At least five sections connected in tandem are used in the representation of each line or cable under consideration in order to maintain an accurate traveling wave model. Proper impedance base changes are introduced to match the TNA model line section parameters to those of the actual transmission lines or cables being studied. For those parts of the system wherein the effect of zero sequence mutual induction between parallel lines is to be investigated, the electromagnetic and electrostatic coupling is included in the model representation as required by the objectives of the study. E-7 Transfer impedance between buses of the underlying system are represented where they are considered significant. Power transformers are represented by model multiple winding transformers, such that the magnetizing characteristics (both positive and zero sequence) are rigorously represented, as are all other’ transformer impedances. The circuit breakers are represented by an electronic switch capable of separate and accurate angular adjustment on both the opening and closing contacts between phases and with respect to the driving voltage sine wave. The opening contacts are adjusted to open on successive current-zeros, just as on an actual circuit breaker. The opening and the closing contacts of the switch are so arranged that resistor pre-insertion is accurately modeled (both resistor magnitude and pre-insertion time). The surge arrester is modeled completely electronically with Zener diodes, thyristors, and high quality operational amplifiers. Sparkover is controlled by an adjustable comparator circuit which fires a thyristor to start the arrester conduction period. A current-limiting gap arc voltage of adjustable waveform duration can be easily modeled when necessary. The nonlinear volt-ampere characteristic of arresters is simulated with resistors and zener diodes to give a ten segment piecewise linear approximation of the actual arrester. The arrester model ceases conduction when the current reaches the thyristor holding value, which is essentially zero compared with the currents encountered in the simulation. The arrester model has an "off" impedance of 20 megohms, which is lower than actual arresters, but this value does not cause any significant draining of charge from the transmission systen. Oscilloscope probes are used to directly monitor the voltages at various points around the system. Copies of all the waveforms are obtained using the TNA-PRIME Computer Data Acquisition System. Study Procedures I. Manual Control of Circuit Breaker Operation For energizing, reclosing, or restriking investigations, the position of the individual closing contacts of the three phases of the switch representing the operating circuit breaker are varied and adjusted both with respect to the driving voltage sine wave and with respect to each other, within circuit breaker operating criteria of maximum allowable span between poles, to produce the most severe transient voltages for each system configuration and switching operation studied. For investigations of overvoltages following circuit breaker opening operations, the model system is first energized, and then, after all energizing transients have subsided, the contacts of the TNA switch are adjusted to open on successive current zeros, just as on an actual circuit breaker. TNA Model Surge Arrester is applied whenever it is believed that its operation would influence the transient conditions. For arresters with current limiting gaps, the model is sparked over at some point between reseal rating and maximum guaranteed sparkover voltage of the arrester to give maximum magnitude to successive voltage crests in the modified transients voltage wave. Arrester discharge currents and the modified transients are observed and recorded. For the analysis of metal-oxide arresters, the voltage, the current, and the dissipated energy are recorded. Such records are examined to determine the minimum applicable surge arrester rating consistent with reasonable system operating procedures. E-9 II. Computer Controlled Statistical Circuit Breaker Operations The generation of a statistical overvoltage distribution on the TNA is accomplished through the use of the digital computer data acquisition system associated with the TNA facility. The computer controls the TNA circuit breaker in a statistical manner to simulate the natural variations in actual breaker closing angles and closing span, and processes the resultant overvoltages and currents. Closing angle is the angle on the power frequency wave at which the breaker closes. Closing span is the difference in electrical angle or time between the first phase of the breaker to close and the last phase to close. In the simulation, the individual phases of the breaker are made to close with equal probability anywhere within the closing span guaranteed by the breaker manufacturer. Since the maximum closing span is generally smaller than a complete cycle of a power frequency wave, the mean value (in time) of the random closings also must be _ evenly distributed over a full cycle. This is accomplished by uniformly stepping the mean of the closing span over an integral number of cycles. When investigating transient overvoltages, the waveforms occurring for each event are processed by the computer, which detects the peak voltage for each of the three phases, sorts the events in order of decreasing per unit overvoltage, and plots the probability distribution. For further analysis, a table of events with the highest overvoltages is printed, showing the overvoltages and breaker closing angles for the three phases. When arrester energies are being measured, the digital computer multiplies voltage and current for each phase, integrates these products over a specific time span, and again plots the results. E-10 The reported distribution curves directly indicate the probability of a given overvoltage or arrester energy. The higher the overvoltage level, the less likely it is to occur. This information can be used with the METIFOR programs to determine the flashover probability of transmission lines. E-11
