PURPOSE:To supply surplus power of the generated power to a dummy load steplessly and efficiently and to avoid the danger that the generated power flows back to a power receiving facility, in an induction generator provided in the power receiving facility. CONSTITUTION:The output of an induction generator 1 which has been converted to d.c. is converted by a converter 3 to a.c. power required by a load system 5 and a dummy load 7 and a switching circuit 8 are connected in series and the serially-connected dummy load 7 and the switching circuit 8 are connected in parallel with a specified power circuit section and the switching circuit 8 is pulse-width-controlled in correspondence to the generated quantity of power and the quantity of load power of the load system. In this case, the serially-combined dummy load 7 and switching circuit 8 can be connected to a d.c. circuit before the converter 3 and the switching circuit 8 can be pulse width-controlled in correspondence to the d.c. voltage value or a capacitor 6 of a specified capacity can be connected in parallel with the d.c. circuit. |
