USED 6.25MW GENERAL ELECTRIC TURBINE GENERATOR. 900# STEAM. BACKPRESSURE TYPE, 4-STAGE TURBINE. 890 PSIG @ 845°F INLET PRESSURE, 150 PSIG EXHAUST PRESSURE. 8524 RPM TURBINE SPEED. 1800 RPM. 4-POLE SYNCHRONOUS WITH 6250 KW AT 13200 VOLTS. TOTALLY ENCLOSED AND WATER TO AIR COOLED. EXCITATION FROM AC BRUSHLESS EXCITER AND BASLER REGULATOR. MECHANICAL OVER SPEED BOLT, LOW LUBE OIL PRESSURE TRIP, AND HIGH EXHAUST PRESSURE TRIP. BENTLEY-NEVADA VIBRATION AND RTD BEARING TEMPERATURE INPUTS ARE FED TO GE MULTI-LYN PROTECTIVE DEVICE, AS ARE ALL ELECTRICAL-END SAFETY DEVICES. THE LUBRICATING OIL SYSTEM IS TRIPLE REDUNDANT WITH GEAR DRIVEN PUMP FOR NORMAL OPERATION, AN AC OIL PUMP WERE THE GEAR DRIVEN TO FAIL, AND A DEC PUMP FOR ROLL-DOWN IN THE EVENT BOTH OTHER PUMPS WERE TO FAIL. LUBE OIL IS CONTINUOUSLY PURIFIED THROUGH A "FILTER-DYNE" VACUUM-TYPE PURIFIER (SUMP-TO-SUMP). THERE IS AN INSTALLED TUBE AND SHELL HEAT EXCHANGER FOR TUBE OIL COOLING AND A PLATE AND FRAME COOLER FOR SUMP-TO-SUMP AUXILIARY COOLING IF REQUIRED. THRUST AND TURBINE JOURNALS ARE TILTING-PAD EQUIPPED WITH VIBRATION AND TEMPERATURE MONITORS. UNIT COMPLETELY REBUILT 5/97 AND RETROFITTED WITH COMPLETE NEW CONTROL SYSTEM. SYSTEM CONSISTS OF A HIGH-PRESSURE CONTROL OIL SKID WITH REDUNDANT PUMPS, NONFLAMMABLE HYDRAULIC OIL, AND A PARKER/HANNIFIN ELETRO-HYDRAULIC SERVO AND POSITIONER. POSITIONER CONTROLLED BY WOODWARD 505 GOVERNOR AND FINAL DRIVER DEVICE. WOODWARD GOVERNOR CONTROLLED BY PC-BASED "WONDER-WARE" PROGRAM WHICH ALLOWS FOR AUTOMATIC START-UP, TIMED WARM-UP BASED ON DOWNTIME, SYNCHRONIZATION, AND BREAKER CLOSURE. SHUT-DOWN IS COMPLETELY AUTOMATIC. CONTROL SYSTEM IS CONFIGURED TO RUN GENERATOR ISOLATED.
