Method of controlling rotating a main field converter

摘要

A generator system includes a generator 102 having a stationary portion 116 and a rotating portion 118. An exciter field winding 120 and a main armature winding 122 are disposed on the stationary portion. An exciter armature winding 128 and a main field winding 138 are disposed on the rotating portion. A frequency demodulator 124 is configured to extract a frequency modulated control signal from the exciter armature winding and to demodulate the frequency modulated control signal to generate a demodulated control signal. The generator includes a main field rotating power converter 136 to selectively control current in the main field winding in response to the demodulated command signal. The generator system includes a generator control unit 104 in electrical communication with the generator to monitor the output voltage at the main armature winding and to output an exciter current including the frequency modulated control signal to the exciter field winding based on the output voltage.
