摘要 |
Provided is a wind power generation system intending to suppress an increase of torque when a voltage in a utility grid is restored, and to reduce a load to devices due to the torque. The wind power generation device is provided with a blade control unit 22 configured to control a pitch angle of wind turbine blades. The blade control unit 22 controls the pitch angle of the wind turbine blades such that a rotation speed of the power generator 6 becomes equal to or greater than a synchronous rotation speed when the power control unit 21 de-actuates the operations of the converter 14 and the inverter 16, and controls the pitch angle of the wind turbine blades such that the pitch angle matches a target pitch angle that is determined based on one of a wind speed, a rotation speed of the power generator 6, and a requested output power when the power control unit 21 re-actuates the operations of the converter 14 and the inverter 16. |
