Abstract

PURPOSE:To enable power to be stably fed according to load fluctuation, by operating a storage battery and an AC generator in parallel with each other. CONSTITUTION:At the time of midnight, AC power fed from a power system via a switch 9 for a power source is converted to DC power by a rectifier 1, and a storage battery 3 is floating-charged. By operating the storage battery 3 and an AC generator 6 in parallel with each other at the time of a peak in the daytime, power is fed to a load 10. So far as a controller 4 is concerned, by the command of contract demand excess estimate, the power switch 9 is released on one side, and on the other side, the AC generator 6 is started. By a phase detection comparing circuit 8, synchronous detection is executed at the point of time when the generated voltage of the AC generator 6 is established, and a generator switch 5 is made.
