Abstract
A wind turbine includes: a wind turbine rotor; a nacelle supporting the wind turbine rotor rotatably; a yaw rotation part configured to rotate the nacelle; and a yaw control part configured to operate the yaw rotation part in a yaw rewind mode of rotating the nacelle in such a direction that a yaw angle changes toward zero, if an absolute value of the yaw angle exceeds a threshold which is variable in accordance with a wind-velocity parameter representing a magnitude of a wind velocity. The threshold increases with an increase in the wind-velocity parameter.
