ABSTRACT:
A variable speed constant frequency synchronous electrical generating system includes a generator rotor with a polyphase field winding whereby the position of the electromagnetic field relative to the rotor structure can be controllably varied. The system includes means to substantially instantaneously determine the angular or rotational position of the generator rotor relative to a reference member rotating at a reference speed; whereby the angular position of the generator electromagnetic field relative to the structure of the generator rotor is maintained essentially the same as the angular position of the reference member, rotating at a reference speed, relative to the generator rotor. As a consequence, the rotational speed of the generator electromagnetic field is essentially the same as the reference rotational speed of the reference member, and is substantially independent of the rotational speed of the generator power input shaft. The system includes means to electronically synthesize a reference rotational speed.
