Independent, redundant overvoltage protection for a generator |
摘要 |
A generator controller provides independent and redundant overvoltage protection to an associated generator. The generator controller monitors the generator output at a first point of a regulation and a second point of regulation. A generator control unit (GCU) provides overvoltage protection based on the generator output monitored at the first point of regulation, including 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. A overvoltage protection unit (OPU) provides independent, redundant protection based on the generator output monitored at the second point of regulation, including at one of tripping a second GCR to remove excitation from the exciter winding and tripping the GLC to disconnect the generator output from the bus. |
