PURPOSE:To eliminate the mutual interference by applying a correction command from at least one control system to the other control system of effective and reactive power control systems. CONSTITUTION:The DC output of a fuel battery 1 is converted by an inverter 2 into an AC, and supplied to a power system 4 through a transmission line 3. The outputs of an effective power setter 13 and a reactive power setter 14 are respectively compared by comparators 9, 15 with effective and reactive powers, the deviation is applied to an effective power control arithmetic unit 15 and a reactive power control arithmetic unit 16, and PID-calculated. The outputs of the unit 15, 16 are respectively applied to comparators 11, 12, a voltage correcting coefficient unit 17 and a phase correcting coefficient unit 18. The outputs of the comparators 11, 12 are applied to a phase control arithmetic circuit 19 and a voltage control arithmetic circuit 20, and control signals from the circuits 19, 20 are applied to an inverter 2 through a waveform controller 21. |
