Abstract
A reference signal generator generates a variable reference signal with which a signal indicating the momentary rotational speed of the prime mover (such as a gas turbine) for a generator is compared, to produce a rotational speed control signal in accordance with a signal representing the load applied to the prime mover, so as to compensate for the rotational speed fluctuation caused by load connection by holding the rotational speed of the prime mover above the desired level during no-load operation and at the desired level under load.
