Abstract
A method for controlling wind alignment correction of a wind turbine comprises: acquiring environmental wind speed values, wind alignment angle measured values, and generated power values of the wind turbine in real time; dividing each acquired environmental wind speed value into multiple wind speed sections according to the magnitude of the environmental wind speed value, and extracting wind alignment angle measured values and generated power values in at least one wind speed section; determining a maximum value of extracted generated power values in each wind speed section; calculating a wind alignment correction deviation of the wind turbine according to a wind alignment angle measured value corresponding to the maximum value; and performing correction processing on a subsequently acquired wind alignment angle measured value by using the wind alignment correction deviation.
