PROBLEM TO BE SOLVED: To provide a feeder system capable of preventing generation of adverse tidal current from an inverter to an electric power system and, when a plurality of AC power supply units are provided, increasing the life and reliability of the respective power supply units. SOLUTION: Respective CPUs 16, 16 which are provided on a pair of AC power supply units 21, 21 forming the power supply system control output power from the inverter 7 so that incoming power from a power system 4 may not drop to below reference incoming power. If a difference occurs between outputs from the respective inverter 7 because of variations in the characteristics of the inverters 7, 7, the CPU 16 changes the reference incoming power in the inverters 7 according to the output power from the inverters 7. It is thus possible to eliminate variations in the outputs from the respective inverters 7. |
