Robert_S_Kerr_Generator_Test_Report Part 2.pdf

This document provides details for a federal contract solicitation to rehabilitate turbine and generator units at the R.S. Kerr Power Plant in Oklahoma. The Army Corps of Engineers seeks to replace the Kaplan turbine runners with new units rated at 49,300 hp to accommodate rewound generators. Work will include replacing turbine head covers, wicket gates, shafts, runners, bearings, operating rings, and servomotors. The contractor must also rewind the generator stator windings on units 1 through 4 to a rating of 37,895 KVA at 0.95 power factor with temperature rise not exceeding 75 degrees Celsius above 40 degrees Celsius discharge air temperature under full load. The solicitation also offers options to replace generator stator cores and reinsulate field windings. Additional rehabilitation involves refurbishing generator and turbine components like bearing pads, thrust bearing shoes, and runners. One new set of thrust bearing shoes will be provided as spares.
