PROBLEM TO BE SOLVED: To perform demand balance without using a circuit for discharging power such as heater, by efficiently controlling the pitch angle even if the demand balance of power falls into the excessive supplying state. SOLUTION: When a power generating method of a DC link is adopted in order to restrain the output fluctuation to be generated caused by fluctuation of wind, output of a power generator is automatically adjusted by temporarily storing electric power to a storage battery 9 as a function for preventing voltage from being raised resulting from excessive output to a system in the case where the system power demand is very low and less than output of a wind power generator and by decreasing the power generating amount through a process of adjusting the pitch angle of a blade by using the voltage of the storage battery as a wind speed signal and a pitch angle control signal in the case where the voltage of the storage battery 9 is further raised. |
