Abstract: Provided are a yawing control method and a yawing control device for a wind turbine. The yawing control method includes: acquiring first wind information at a current moment characterized by current operation data of a neighbor wind turbine adjacent to the wind turbine when at least one of a wind direction sensor and a wind direction data uploading path of the wind turbine fails; acquiring second wind information matched with the first wind information in wind information characterized by historical operation data of the wind turbine at all moments; and performing yawing control on the wind turbine based on the second wind information.

Abstract: A wind turbine and an operational control method therefor are disclosed. The method comprises: obtaining current directional data from the nacelle of the wind turbine; and, according to the directional data, positional data of each wind turbine of a wind farm, as well as wind condition data as measured by each wind turbine, and controlling operational equipment of the wind turbine, so as to increase power generated by the wind turbine. According to the current direction of the nacelle of the wind turbine, positional data of each wind turbine of a wind farm, and wind condition data as measured by each wind turbine, accurate control policy adjustment is performed in advance on operational equipment of a wind turbine, thereby increasing the power generated by the wind turbine. A device for implementing the control method is also disclosed.
