Abstract
A wind power generation system is disclosed for suppressing 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 system includes a blade control unit for controlling the pitch angle of the wind turbine blades such that the pitch angle matches a target pitch angle determined on the basis of at least one of a wind speed, a rotation speed of the power generator, and a requested output power when the power control unit re-actuates the operations of the converter and the inverter.
