Claim 0:
1. A method for controlling a wind turbine, comprising:
obtaining a wind speed associated with the wind turbine;
obtaining a wind direction corresponding to the wind speed;
determining a plurality of variation angles of the wind direction, comprising:
for each unit time from a plurality of different unit times, calculating a corresponding angle variation value per unit time of the wind direction, so that the plurality of variation angles of the wind direction are determined according to the plurality of different unit times, respectively;

determining a yaw control precision corresponding to the wind speed based on the plurality of variation angles of the wind direction, wherein the yaw control precision is reduced from a first angle to a second angle which is equal to an average of the plurality of variation angles of the wind direction; and
performing a yaw tracking for the wind turbine according to the yaw control precision, so that a start of the yaw tracking for the wind turbine is changed from when a variation angle of the wind direction within a first time period reaches the first angle and lasts for a second time period at the first angle to when the variation angle of the wind direction within the first time period reaches the second angle and, lasts for the second time period at the second angle.
