GENERAL ELECTRIC 9.3MW STEAM TURBINE–GENERATOR

THE GENERAL ELECTRIC 9.3 MW STEAM TURBINE–GENERATOR IS A HIGH-EFFICIENCY, 2-POLE, 3-PHASE SYNCHRONOUS MACHINE DESIGNED FOR CONTINUOUS INDUSTRIAL AND UTILITY-SCALE POWER GENERATION. IT OPERATES AT 60 HZ AND IS CONFIGURED IN A WYE (Y) CONNECTION, PRODUCING A RATED APPARENT POWER OF 9,375 KVA WITH AN OUTPUT VOLTAGE OF 4,160 V AND A FULL-LOAD CURRENT OF 1,303 A. THE GENERATOR ACHIEVES OPTIMAL PERFORMANCE AT A 0.80 POWER FACTOR, DELIVERING APPROXIMATELY 7.5 MW OF REAL POWER UNDER NORMAL CONDITIONS. EXCITATION IS PROVIDED BY A 125 VDC FIELD SYSTEM DRAWING 221 A, ENSURING STABLE VOLTAGE REGULATION AND RELIABLE SYNCHRONIZATION WITH GRID OR PLANT SYSTEMS. THERMAL MANAGEMENT IS A KEY DESIGN FEATURE: THE ARMATURE TEMPERATURE IS LIMITED TO 100 °C (MONITORED BY DETECTOR SENSORS), WHILE THE FIELD WINDING MAY REACH UP TO 125 °C (RESISTANCE-BASED MEASUREMENT). THE UNIT IS RATED FOR AMBIENT COLD AIR INLET TEMPERATURES UP TO 40 °C AND A COOLING WATER INLET TEMPERATURE OF 95 °F, MAINTAINING OPERATIONAL INTEGRITY UNDER DEMANDING THERMAL LOADS.
