Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To attain high-speed control of generated power and reduction in received electric power from a commercial power system, by computing a reduction in received electric power based on the capacity of a running generator, subtracting the reduction in received electric power from a received power reference value to output a target received electric power, and adjusting a generated power command value. SOLUTION: This controller for private power generator includes a target- power computing circuit 17 computing a target value of generated power, which is inputted into governor control circuits 5a, 5b. The governor control circuits 5a, 5b output a rotational-speed command to governors 4a, 4b based on the target value of generated power and rotate driving motors 3a, 3b. The driving motors 3a, 3b drive the motors 2a, 2b to generate electric power, and the generated power is consumed by a local load 6 through a generation breaker and a load breaker 15. The shortage of consuming power in the generated power of the motors 2a, 2b is supplied from a commercial electric source 1 through a received power breaker 13 so as to compensate for it. It is thus possible to control electric power at high speed and recover received electric power to a setting value immediately.
