Abstract
A method and an apparatus for yaw control of a wind turbine under a typhoon. The method for yaw control may include: determining, before or when the typhoon comes, whether there is a fault in a yaw system of the wind turbine; performing a normal yaw control over the wind turbine according to the wind direction, if determination is negative; and performing a yaw control corresponding to the fault on the wind turbine according to the wind direction, if determination is positive. The yaw control corresponding to the fault is performed before or when the typhoon comes, in case of one of a yaw drive mechanism fault, an electronic brake mechanism fault, or a hydraulic brake mechanism fault. The wind turbine is downwind oriented and yaw load reduction is achieved.
