摘要： PURPOSE:To operate a generating system at low cost with an induction motor, by preventing a reverse power flow without using a protective relay. CONSTITUTION:Reactive power for drive and operation is fed to an induction motor 2 and first and second loads 7 and 8 from an inverter unit (A), in which a discharging converter 12 is connected through a power cable to a charging converter 10, and a smoothing capacitor 13 is connected with the power cable 11. When the power required from the loads 7 and 8 is over a rated value of an induction generator 2, the rated value of power of the induction generator 2 is all fed to the first and second loads 7 and 8, while the surplus power is fed for the loads 7 and 8 from the commercial power-supply line 9 through the inverter unit (A). In this way, all loads are driven. When the loads are below the rated value of the induction generator 2, the whole quantity of the power is fed from the induction generator 2.
