PROBLEM TO BE SOLVED: To suppress maintenance cost of facilities by reducing a reverse phase stress of a rotary power supply device and to contribute to performance improvement of an entire system by controlling an output current of a stationary power supply device in accordance with a voltage or a load condition of an AC electromotive system.SOLUTION: A power supply system includes: a voltage detector 9 for detecting a voltage of an AC electromotive system 21; a voltage state determination section 13B of the AC electromotive system 21 for determining whether the voltage of the AC electromotive system 21 detected by the voltage detector 9 is in a standard voltage state or in a low voltage state; a current control section 18 for making an output current of a stationary power supply device 5 follow up a reference current; and a reference current regulation section 16 for regulating the reference current. When the voltage state determination section 13B determines that the AC electromotive system is in the standard voltage state, the reference current regulation section 16 preferentially outputs a reverse-phase component and when the voltage state determination section 13B determines that the AC electromotive system is in the low voltage state, the reference current regulation section 16 preferentially outputs a reactive component. |
