ABSTRACT:
The field excitation flux of the synchronous generator is controlled in response to the summing rotor angle signal of a predetermined set signal and of a rotor angle signal representing a phase difference between the voltage equivalent to an infinite bus voltage and the output voltage from the pilot generator provided on the same rotating shaft as the synchronous generator.
