INTRODUCTION, EXECUTIVE SUMMARY AND RECOMMENDATIONS Introduction This report presents the results of inspection and tests as well as recommendations for the potentia 1 use of the turbine-generator set which was originally intended for the Akutan Hydroelectric Project in 1980. The turbine generator set was manufactured by the Chungking Water Turbine Works in the Peoples Republic of China and has never been used. Because of the concern stemming from the 9-year storage in an un- heated warehouse in the Seattle area, during which the equipment could have deteriorated mechanically and electrically, the APA has requested our assis- tance in the inspection and testing of the unit. The inspection and testing service were performed on May 15-16, 1989. Executive Summary and Recommendations The turbine-qenerator set has been stored in seven wooden crates an unheated warehouse. The crates were transported to Hydrowest Group, Inc. our testing subcontractor 1 S shop and opened under our witness. Generally, internal packaging was thorough and well done, preserv- ing the contents of the crates in good factory condition. No major signs of shipping or weather damage was seen. Because of the good physical condition, no significant disassembly of parts was attempted and the vi sua 1 inspection was deemed adequate for determining the overall mechanical condition of the unit. A review of the turbine governor indicated that the governor lacks prov1s1ons for automatic or remote operation and is of an unusual design which would prove difficult to maintain. We also suspect the speed and frequency governing capabilities of this unit are not suitable for use in an isolated electrical system. · Limited electrical testing was performed on the generator. The results indicate the generator is devoid of moisture damage. The generator and exciter control cabinets were in apparent operating condition but were deemed unsuitable for application by the Alaska Power Authority (APA). Elec- trical clearances and materials in the control cabinets do not meet the National Electrical Code and other standards. Wire bundles are brittle and could easily break under normal bending. Control switch operations and indi- cations were imprecise and confusing. The exciter control cabinet has minor water stains and shows oxidation on parts. Under energization, the generator circuit breaker would pose safety problems to operating personnel because of numerous exposed live parts around it. We determined that energization of the control equipment was not necessary. Recommendations --The following recommendations are for general improve- ments and mod1fications necessary for most future applications of this turbine-generator set. Specific recommendations relating to the Akutan project are grouped separately later in the report. - 2 - 1. The turbine, flywheel, generator and inlet valve should be retained for potential use by the APA. A final decision re- garding use of this equipment or its disposal should consider the specific project on which it might be used, the cost of upgrading the equipment for reliable remote and automatic operation, and the cost of more modern, new equipment. 2. The generator and exciter control equipment should be dispos- ed of. New modern control equipment conforming to the National Electrical Code and applicable manufacturing and performance standards wi 11 be required before the turbine- generator can be put into operation. 3. The turbine governor should be disposed of. 4. Options for upgrading the equipment should consider 11 packag- ing11 the turbine generator as part of a skid-mounted equip- ment set. The set, including a new governor, unit controls and the inlet valve, could be shop assembled to reduce the cost and time required for field installation. 5. If the equipment is to be operated in a remote area, such as Akutan, then a remote monitoring capability should be provided. 6. All documentation should be preserved as future references. 7. Rotational tests should be performed in the field to confirm design and operational criteria. II. INVENTORY OF EQUIPMENT In order for the equipment to be transported from the warehouse and inspected, we contracted Hydrowest Group, Inc., a Bellevue, Washington firm specializing in turbine testing and retrofit. Under our witness, crates were opened on the morning of May 15, 1989. Crates contained the following assemblies: Crate No. Al -Turbine Crate No. A2 -Turbine Parts Crate No. A3 -Generator Crate No. A4 -Static Exciter Cabinet Crate No. A5 -Governor Crate No. A6 -Generator Control Cabinet Crate No. A7 -Valve Assembly The inventory of the materials were made by cross checking the crate contents against the materia 1 1 i sts on equi ~ment. assembly drawi n~s. This was the only means available for a comprehenslVe 1nventory as pack1ng lists were not provided with the crates. Results of this check are presented in Hydrowest's attached Inspection and Testing Report. - 3 - III. INSPECTION AND TESTING As each crate was opened, a visual inspection was made of equipment and components inside. Component disassembly, such as of bearings, was not necessary because of the near-factory condition of the equipment. The static exciter cabinet showed a moderate degree of oxidation on internal components and had water stains on the cabinet. Our observations and findings are as fo 11 ows: Turbine --The turbine crate was in good structural condition. Upon opening the crate all equipment was found to be enclosed in a continuous plastic sheet covering. All unpainted parts were heavily wrapped, bagged or coated with cosmoline-type rust inhibiting coatings. All heavy com- ponents inside the crate were bolted to the crate. There was no evidence of parts movement, mechanical damage or moisture damage to the equipment. The turbine shaft could be rotated by hand approximately 30 degrees. The turbine runner had been apparently tied off to prevent rotation. The flywheel side generator bearing cap was removed and the cap interior and bearing exterior examined. No oxidation of metal surfaces was noted. Grease around the bearing appears to have thickened to a very soft waxy consistency. No separation or solidification of the lubricant was found. Limit switches and solenoid valves appeared in good condition although functional tests were not performed. Governor --Governor components were packaged in the same manner as the turbine and are also in good condition. The governor design u~es a large flyball arrangement to drive the governor main distributing va.ve direct- ly. This design results in higher governor power consumption and reduced speed control capability. All controls for speed adjustment, dashpot time, needle limit and deflector limit are manual handwheels or levers. All handwheels and levers could be operated. An automatic mechanical overspeed shutdown control and electric solenoid shutdown control are provided. Valve Assembly --The valve assembly, a 250mm (approx. 10-inch) gate-type shutoff valve with electric motor operator, was also found to be in good condition. The actuator, made by the Tianjin factory in China, has an exterior configuration very similar to actuators made by Rotork. It is assumed the actuator design is based upon a Rotork product. Electrical tests of the actuator were not performed. Flywheel --The flywheel appeared to be in good condition. As this crate contains no electrical or lubricated parts no upgrading or cleaning of these components are considered necessary. - 4 - Electrical Generator --The generator was taken to General Electric•s Apparatus and Engineering Service Operation, Kent, Washington. The generator was in good condition. There was no visual indication of moisture or corrosion damage. The rotor was free and turned easily by hand. The stator windings were subjected to insulation and polarization index tests for 10 minutes with one minute interval readings. A Megger test was applied to the rotor winding. The readings were taken using a Series 1 Biddle 500-volt motor-driven megger, calibrated November 14, 1988. Both results showed that the windings were dry and insulation was good. The test results are included in Hydrowest•s report. Generator Control Cabinet --The control cabinet was manufactured by Zigong Electrical Apparatus Work. The control cabinet has front and rear doors with no gasket. The front door is half height. The upper half of the control cabinet is occupied by indicating meters and control switch- es. Behind the front door and on a subpanel included control circuit breakers, watt hour and warhour meters, overcurrent re 1 ays and timers. The generator circuit breaker is mounted inside the control cabinet at rear and accessible through the rear door. When the operator opens the door to operate the breaker, he is subjected to live 480-volt buses and contacts around the breaker handle. The following highlights some of the features of the control cabinet. a. Generator Circuit Breaker --The generator circuit breaker, rated 380 VAC, 400A (nameplate data), is mounted on the rear panel behind the door. The 380 VAC rating is nonstandard and underrated for the generator voltage. The circuit breaker is actually an open 3-pole switch. Contacts are exposed and electrically latched with springs to maintain the contact pressure. No contact wiping action is provided. In series with the breaker is a manually operable 3-pole safety switch. The safety switch is operated by a handle from out- side the cabinet. b. Overcurrent Re 1 ays --These are the only protective re 1 ays provided with the unit. No individual product catalog is provided for the re 1 ay. The namep 1 ate does inc 1 ude a crude relay setting diagram embossed with nameplate data. The set- ting would at best be approximate. c. Control Switches --Return-to-neutral momentary switches have mechanical targets. Targets are red and white instead of conventional red and green. Targets can stop at an intermed- iate position unless the handle is fully turned to the ex- treme pas it ion. The Emergency Stop switch is a 3-position maintained type instead of a standard red pushbutton switch. -5 - d. Indicating Lights --Indicating lights are rectangular and are either red or green. Use of color is unconventional. Red and green are used interchangeably to designate the same function on different switches. Exciter Control Cabinet --The exciter control cabinet is built similarly to the generator control cabinet, but was manufactured by Chengdu Recti- fier Works, a different manufacturer. This cabinet is characterized by a 1 a rge exhaust fan mounted on top to coo 1 the SCR units. There are some water stains on the cabinet. This is the only crate which did not have an i nterna 1 p 1 ast i c sheet wrapping. Oxidation residues were found on wires and contacts. Wire bundles were varnished and appeared very brit- tle. Multipin connectors were connected via varnished wire bundles in- stead of flexible multiconductor cables. Very close clearances between bus bars and wires exist and in some cases, nearly touch each other. We judged that the workmanship was inferior to the generator control cabinet. Spare Parts --Very few electrical spare parts were supplied and obtain- ing Chinese spare parts may prove to be a significant problem in the future as no American equivalent parts are readily available. IV. MANUFACTURERS• DOCUMENTATION Documentation is provided in Chinese and English. Detailed as- sembly drawings and circuit diagrams were furnished with the equipment. The accuracy of the information on the drawings was not confirmed, except for the material lists during the inventory. V. RECOMMENDATIONS FOR AKUTAN PROJECT The following recommendations are based on the assumption that the turbine-generator wou 1 d be used for the Akutan project as originally propos- ed. However, the same recommendations would be generally applicable to other projects as well. 1. Hydroelectric Design and Efficiency Evaluation of this equipments• design head, power output and effic- iency, in relation to site conditions at Akutan, should be made be- fore upgrading of the equipment is considered. More modern equip- ment may be more suitable depending upon how well matched this equipment is to the Akutan site and the extent of upgrades required. 2. Upgrades possibly Required for Automatic or Remote Operation The following upgrades to the turbine, generator, and inlet valve are considered necessary for automatic or remote operation: - 6 - a. Incorporation of a modern speed/frequency governing system capable of either needle control (water saving) or deflector control (optimum frequency control, water wasting) operating mode. Governor should also be com- patible with isolated system operation, remote start- up, synchronizing, and load adjust functions. b. Additional protective devices: (1) Bearing overtemperature RTOs - 4 (2) Vibration switches - 1 or 2 (3) Generator stator RTOs - 2 (4) Governor low oil level and pressure switches (5) Remote speed indicating transducer (6) Needle and deflector position transducers 3. Upgrades Possibly Required for Reduced Maintenance The following upgrades might be considered to reduce on-site main- tenance effort and to improve maintainability: a. Obtain a complete set of spares for electrical trans- ducers, switches, relays, fuses and controls. b. Obtain a spare inlet valve motor operator. c. Add automatic grease lubrication system for the gen- erator and turbine bearings. 4. Options for Factory Modifications and Upgrades Prior to Site Delivery Installation of this unit at a remote site would be greatly simpli- fied by combining the turbine-generator into a skid-mounted equip- ment package. Shaft alignment and electrical checkout could then be completed in a shop setting rather than in the field. The total skid-mounted package might include the turbine, flywheel, gener- ator, governor, exciter, controls and hydraulic pressure unit. This option should be considered in evaluating this equipment's suitability for use on the Akutan project. 5. Controls and Monitoring Control systems should be redesigned and newly procured to meet the expected operations scheme. Stand alone automatic operation re- quiring very little human intervention is desirable. A static ex- citer and controller based on the original control schematic and having automatic voltage regulation capability should be supplied. The generator breaker should be housed in a separate deadfront en- closure and mounted either as a part of the generator control panel or at a separate location. - 7 - 6. Supervisory Control It would be desirable to implement a simple supervisory and alarm system which can monitor the equipment functions from a remote location. This function could be implemented by a synthesized voice warning autodialer, a remote annunciator panel, or a SCADA system connected to the APA headquarters, assuming adequate commun- ications link can be installed. 7. Documentation A 11 copies of the supp 1 i ed documentation shou 1 d be preserved and used for future references. The electrical control schematic dia- grams and descriptions should be used in the design of new control systems. VI. STORAGE AND SHIPPING PROVISIONS Space heaters with thermostats have been installed in the crates to prevent accumulation of moisture during shipment to and storage in Anchorage. Details of the heater installation is included in the Hydrowest•s report. -End of Report - (3223Y) TURBINE -GENERATOR AND CONTROL EQUIPMENT INSPECTION AND TESTING REPORT 17 MAY 1989 PREPARED FOR R.

Equipment was packed and protected to prevent damage and corrosion. One end of Crate Al and the top of Crate A2 were removed for inspection. The turbine and parts inside Crate Al were found to be clean with no signs of any corrosion or oxidation. The equipment appears to be in factory condition. All components were carefully packed and there was no shipping damage. The turbine bearing cap, on the generator side of the turbine, was removed. The interior of the bearing showed no oxidation; however the lubricating grease had hardened. It will be necessary to clean and replace the grease in both turbine bearings prior to operation. The main shaft was rotated and was found to cause of the block is unknown but it is intentional shipping block. be blocked.

Two space heaters, thermostat controlled, will be installed inside the turbine crate. Refer to instruction sheet attached. In order to check the loose parts shipped inside the crates, we used the material list data included in the assembly drawings. These lists are included as a separate attachment. The following list is a quick summary of the complete lists. 4 Referring to those details we found that for: A. B. Inlet Pipe Assembly: Dwg. No. D6003/l-00. accounted for and are located in Crate Al. All parts were Nozzle Assembly: Dwg. No. D6003/2-00. The nozzle is assembled and installed into the turbine case. It is assumed that the assembly is complete. C. Control Part: Dwg. No. D6003/3-00. All parts were accounted for and are located in Crate Al. D. Rotating Part: Dwg. No. D6003/5-00. The main shaft and associated parts are assembled in the turbine. The parts associated with the flywheel and coupling are shipped loose and are accounted for. The flywheel and its assembly hardware are in Crate A2. E. Floor Plate Assembly: Dwg. No. D6003/6-00. Most parts were located such that complete crate (Al) disassembly would have been required for an accounting. However, it appears all parts and hardware are present. F. Bearing Assembly: Dwg. No. D3709/7-00. Both turbine bearings were assembled and appear to be complete. Again, it is noted that prior to operation the lubricating grease should be replaced. The one loose eyebolt was accounted for. G. Twin Filters: Dwg. No. SL-00/025X40. The filter assembly was complete except for the external piping and valves. The loose pieces were accounted for. There appears to be a part change from the part list on the drawing and the parts shipped. The two valves (Item 15) are called out as Type JllH on the drawing, but the parts shipped are marked J13H. H. Hydraulic Operating Valve: Dwg. No. SF-OOA/032X40. This valve was assembled into the turbine case. It appears complete. The external copper tubing is included; it is tarnished but usable. I.

The crate was completely removed for inspection and testing. The generator was well packed and protected and there was no evidence of oxidation or damage. The shaft was rotated and found to turn freely by hand. A run- out check was done at the end of the shaft with a reading of 0.002 T.I.R. There was no visual indication of moisture anywhere in the unit. Moisture content will be determined by electrical testing. The gene~ator was taken to the General Electric Service Shop, in Kent, to perform the electrical tests required. The tests were done to G.E. standards and the results were compared to the test data supplied from the manufacturer. It was determined that there had been no moisture damage to either the stator or the rotor. Refer to test result sheet attached. The stator windings were tested using the polarization index test with the megger at 500 VDC. The test was done over a ten-minute period and readings were taken every minute. Ten minutes allows for winding saturation. The index is determined by taking the reading at ten minutes (9200 megaohms) and dividing it by the reading at one minute (2500 megaohms). This value is then 3.6. General Electric standards, which are conservative, would show the possibility of moisture problems if the index value was below 3 . 0 . 7 The rotor was megger tested at 500 VDC and the reading was 400 megaohm. This compares with the figure of 20 megaohm stated in the factory test report. This discrepancy may be accounted for by the test methods used at the factory compared to the methods at G. E. A Hi Pot test was considered but after the meggar tests were done and the possibility of moisture problems removed, it was decided it was not required. The generator end cover was removed and the collector/brush assembly inspected. The collector rings are tarnished and it is recommended that they be cleaned and polished prior to use. The generator bearings are grease packed. This old grease should be removed, the bearings cleaned, and then regreased prior to operation. Two thermostatically controlled heaters will be installed in the generator crate. Loose parts included with the generator were checked against the shipping order and all parts are included and are in good condition. These parts include: A. Anchor bolts, nuts and washers (4 sets). B. Pins, 160 x 110mm (2). C. Spare parts including: a. Slope wedge, E1235/2-5 (1) b. Slot wedge, E1235/1-3 (2) c. Constant pressure brush holder, 45041A/25x32 (1) d. Carbon brush, 25x32x65 (6) e.

It was found that the cabinet had been exposed to water (ocean spray, rain, condensation?). The interior of the crate did not offer any uniform waterproof protection and water collected on all exposed surfaces inside and outside the cabinet. Devices appeared in good condition but contacts, assembly hardware, bus bar, mounting supports and w1r1ng are corroded. Where metal parts were protected with paint, the water just left spotting. After review by Hydro West Group and the customer, it was decided that the equipment would most likely not be utilized. A thermostatically controlled heater will be installed and the cabinet re-crated. Loose parts included inside this crate wre two wooden boxes containing spare parts and manuals listed as follows: A.

The exciter could be in serviceable condition; however, it should be tested thoroughly before being put into use. In discussion with the customer, it was decided that no other testing would be required prior to tests after installation. It was decided to recrate the equipment and make it ready for shipment. The customer requested that thermostatically controlled strip heaters be installed in the turbine crate (2 heaters), the generator crate (2 heaters), and the control panel, valve and exciter crates (1 heater each). For information on the heater installation, refer to instruction sheet attached. The bagged dessicant shipped in the crates was unbagged and dried out in an oven. The dessicant was then rebagged and replaced in the crates. The crates will be reassembled and rebuilt as required. All equipment in the crates will be covered with plastic to protect it from the weather. 13 INSPECTION REPORT RECOMMENDATIONS: The turbine/generator equipment appears to be in operable condition. During the meeting with the R. W. Beck engineers and the A.P.A. engineer, the end use (installation) of the equipment was discussed. The preliminary decision was that the turbine, generator and the stop valve would be utilized in the project and that the other equipment, the governor, exciter and control board be replaced with new equipment. The arguments for replacing the equipment were that the governor, as it is, would not operate the turbine automatically and would consume too much power in its operation. In the case of the electrical equipment supplied, the considerations were that it would not meet local and national codes required for that type of equipment and that the parts might be very difficult to replace if they should fail during service. In the case of the electrical equipment, it is recommended that the exciter and control equipment be replaced with modern, domestic counterparts. This change would insure satisfaction of code requirements and would eliminate the problems of having to replace difficult to find parts. The design of this new equipment could be done such that its operation and construction would closely match the existing. This could be done easily using the data and the existing equipment itself as blueprints. For completely automatic function of the turbine/generator equipment, the control equipment could be designed with the necessary systems added. For example: 1. Automatic black start ability. 2. Level/flow control. 3. Machine monitoring and protection. 4. Generator monitoring and protection. 5. Remote annunciation. 6. Remote control. Depending on the application, any or all of these system could be included. The governor control is manual. After starting the machine, the governor operates the needle to maintain correct machine speed and it can automatically shut the machine down in case of overspeed conditions. However, if the equpment is to be located remotely and will not have an operator at hand, it will be necessary to provide either a modification to the existing governor or a new governor for automatic control. In order to use the existing governor it would have to be modified to include electro mechanical or hydraulic actuators to restart the equipment after shutdown. If the electro mechanical actuator is opted for, it would need to have a battery and 14 charging system. If the hydraulic system was used, a power unit and accumulators would be needed. Using either system or providing a different governor would also require the addition of some type of control system. This could be done using a programmable controller with analog capabilities. Since the existing governor is in good condition and can operate the machine after it is running, it seems practical to modify it for automatic start abilities. However, it would be necessary to analyze the costs of the different alternatives for the most feasible choice. In regard to the other equipment, the turbine, generator and the shutoff valve are in operable condition. It will be necessary prior to operation to disassemble all bearing and gear boxes to clean away the old hardened grease and oil. After thorough cleaning the lubricant can be replaced and the units reassembled. While the upper turbine housing cover is off, examine the installation of the runner. Determine the cause of the rotation block and correct. If it is decided to add a more sophisticated control scheme to the turbine operation, it may be necessary to add control devices. These could be speed sensors, position transducers, limit switches, etc. This work should be carried out by the control designers/manufacturers in order to get the best system coordination. In the past when Hydro West Group has provided equipment of this size, it has tried to do as much factory assembly and interconnection as possible. In this case, in order to minimize the on-site installation time and expertise required, we would recommend assembling the equipment onto a common skid in a manufacturer's shop and including the turbine, genrator, governor, exciter and control equipment all assembled and interconnected. This would allow the manufacturer to run the system and operational tests prior to field installation, thereby eliminating most, if not all, of the debug time required during the start-up of new equipment. It would also reduce the time required by the installer. This installation approach has to be weighed against the site location and accessibility and equipment weight restrictions for shipment. For the convenience of the operators, it is recomm~nded that all of the operation and maintenance manual information be rewritten. This should be done in order to eliminate the confusion that could develop from the manuals provided. These manuals are accurate, but the translation is somewhat misleading in some areas and to an operator/owner with little experience they may be of little use. If new equipment is to be interfaced with this equipment, this manual requirement will partially be taken care of. 15 The drawings supplied are generally very legible and should not need to be redrawn. The turbine, generator and valve are ruggedly constructed and should provide many years of trouble-free service. When the time comes for rebuilding any of these items, in many cases direct domestic replacement of parts would be possible; i.e., turbine bearings, valve operator, valve, generator bearings, generator brushes, etc. In the event that it would be required to replace the larger parts, i.e., the runner, shaft, etc., any turbine manufacturer would be able to design, specify and have fabricated a replacement. The costs involved for such a fabrication would have to be measured against procuring the part directly from the original manufacturer. In the case of the generator, in time it may be necessary to rebuild the unit. This work could be done by any of several domestic electrical service shops. 16 SPACE HEATER INSTALLATION INSTRUCTIONS REQUIRED IN CRATES: A1: Turbine Equipment -2 heaters A3: Generator -2 heaters A4: Exciter - 1 heater A6: Control Board - 1 heater A7: Valve - 1 heater HEATER REQUIREMENT: Inside each crate install one or two, 40-100 watt element to operate at 110VAC, provide a thermostat to prevent overtemperature and provide a 110VAC, 2-wire plug with a six-foot cord.
