PROBLEM TO BE SOLVED: To make it possible to operate a power generator in a highly efficient state by controlling a power factor of a power system in a ship according to a designated request value.SOLUTION: A power factor controller 15 calculates a reactive power request value from a power factor setting value set by a power factor setter 15-1 and an effective power detection value detected by an effective power detector 16-2 as well as calculates a reactive power detection value from a power factor detection value detected by a power factor detector 16-1 and the effective power detection value; calculates a reactive power command value from a deviation between the reactive power request value and the reactive power detection value as well as calculates an effective power command value from an effective power setting value set by an effective power setter 15-2 and the effective power detection value; and, when the reactive power detection value exceeds the reactive power request value in the case where a storage battery 7-1 is in a state capable of being charged or discharging, outputs the effective power command value and the reactive power command value to an inverter circuit 23 of a charge/discharge device 7 to make the inverter circuit 23 supply reactive power corresponding to the reactive power command value to an intra-ship bus 4 while making the storage battery 7-1 discharge effective power corresponding to the effective power command value or be charged with power of the intra-ship bus 4.SELECTED DRAWING: Figure 1 |
