The invention relates to a wind turbine yawing wind facing method under an anemoscope fault mode. The method comprises the following steps of: before a fault occurs, establishing a wind direction correlation matrix group between sets; after the fault occurs, establishing a distribution function regression model of the wind direction of a fault set to obtain a wind direction value of a machine position where the fault set is located; checking the wind direction of the fault set through a cabin vibration sensor; and comparing the wind direction included angle and the wind direction value of the sets in real time, and performing fault-tolerant control on the fault set. The method has the beneficial effects that wind direction correlation matrixes are pre-constructed among wind turbine locations, and the wind direction distribution function relationship among the wind generation sets is established. Yawing control of the wind generation sets is mainly carried out on a smaller time scale, and when anemoscope equip
