PURPOSE:To increase the rated output capacity of a generator to a level equivalent to the reception capacity and to obtain a stable power profitably by providing a reception power detecting means and a reception lower limit value setting means, and discharging the excessive power of an induction generator to the outside of a system by a power discharge means when the reception power goes less than a reception lower limit value. CONSTITUTION:When a propeller 8 is rotated by receiving wind, the induction generator 9 is rotated, to be in a power generating state, and a power can be generated by connecting the induction generator 9 to a power generation system R via a bus 10. The reception power can be always detected in real time by a reception detecting means 13, and the minimum level is set by a reception lower limit value setting means 14. When the reception power goes less than the reception lower limit value, a command is outputted to the power discharge means 15, and the output of the induction generator 9 is discharged to the outside of the system by a power discharge means 15 consisting of a reactor and a transistor via a resistor 16. Thereby, it is possible to prevent a reverse tidal current to a reception system from occurring, and to increase and stabilize the output of the generator. |
