CPC H02H 7/065 (2013.01) [H02P 9/10 (2013.01); H02P 29/0241 (2016.02)] | 20 Claims |
1. A method, comprising:
monitoring a point of regulation voltage input to a generator control unit;
monitoring a generator output voltage as a backup point of regulation voltage input;
detecting an overvoltage fault at the point of regulation voltage input, the backup point of regulation voltage input, or both;
opening a first solid-state switch in response to detecting the overvoltage fault to prevent provision of an input signal to a generator excitation field;
opening a generator excitation field relay in response to detecting the overvoltage fault to prevent provision of the input signal to the generator excitation field; and
opening a second solid-state switch at a blocking circuit in response to detecting that an input signal to the generator excitation field is above a voltage threshold that induces the generator output voltage to an overvoltage fault value.
