摘要： If blades have been struck by wind that has reached a power reduction start wind speed that is lower than a conventional cut-out wind speed at which torque acting on a main shaft reaches the torque limit, a wind turbine generator performs torque reduction control for causing the change in the torque when wind speed is higher than the power reduction start wind speed to be different from change in the torque when wind speed is lower than the power reduction start wind speed so as to prevent the torque from exceeding the torque limit at the conventional cut-out wind speed. For example, if the wind striking the blades reaches the power reduction start wind speed, the wind turbine generator sets the slope of change in torque lower than that before the power reduction start wind speed is reached. Accordingly, the wind turbine generator can reduce the load acting on a device and suppress a reduction in power even if the blades are struck by strong wind.
