Patent

CA 2715930

A wind turbine generator is provided with: a nacelle mounting a wind turbine rotor; a yaw drive device generating drive force for causing yaw turning of the nacelle; a brake mechanism generating braking force for braking the turning of the nacelle; a control system controlling the yaw drive device and the brake mechanism; and a wind speed measurement device measuring wind speed. When detecting occurrence of a high wind speed state based on the wind speed while the nacelle is turned by the yaw drive device, the control device provides braking force for the nacelle by using the brake mechanism in response to the detection of the occurrence of the high wind speed state.
