PROBLEM TO BE SOLVED: To provide a wind mill rotation control method of a wind turbine generator system that can produce highest power generation output, by controlling rotation of a wind mill and a power generation motor when the rated wind speed of the wind turbine generator system is exceeded, and controlling rotation of a wind mill and a power generation motor even during the same wind speed, and to provide a proper control method of power generation output.SOLUTION: Power transmission is unified by attaching a backflow prevention member, respectively, to a transmission line of power generated from a power generation facility utilizing natural energy, and a transmission line of power from a commercial power supply. When power is transmitted normally from a power generation facility, it is transmitted at a higher voltage when compared with power transmission from a commercial power supply, and power is transmitted preferentially from a power generation facility. In such a power generation system, the voltage value is detected when power is transmitted from a commercial power supply in a non-normal state, and the voltage value during power transmission from a power generation facility is set higher than the voltage value during power transmission from a commercial power supply. |
