Abstract:
1. A generator controller for providing independent, redundant overvoltage protection for an associated generator, the generator controller comprising: a generator control unit (GCU) that monitors an output of the generator at a first point of regulation and in response regulates the generator output and provides overvoltage protection that includes at least one of tripping a first generator control relay (GCR) to remove excitation from an exciter winding, and tripping a generator line contactor (GLC) to disconnect the generator output from a bus; and an overvoltage protection unit (OPU) that monitors the output of the generator at a second point of regulation and in response provides overvoltage protection that includes at least one of tripping a second generator control relay (GCR) to remove excitation from the exciter winding and tripping the GLC to disconnect the generator output from the bus.
