ABSTRACT:
A prime mover control system is provided that can prevent magnification of power fluctuation, included in a feedback signal, that occurs between a generator and a power system, and that enables stable operation of the prime mover to continue, without disturbing the power system. In the case where a deviation detection device (1a) that receives as input an output-power command value signal indicating a command value that is a target for the output power of a generator driven by a prime mover and an output-power signal indicating the present value of the output power, and that outputs a deviation signal indicating the deviation between the command value and the present value of the output power, and in the case where a control device (3a) that receives as an input the deviation signal and outputs a control output signal for controlling the output of the prime mover, a filtering device (2a) is provided that, in the output-power signal, the deviation signal, or the control output signal, attenuates or eliminates predetermined frequency components caused by periodic fluctuations, in the output power of a generator, that occur due to discrepancy between the output of the prime mover and the generator output power.
