A yaw auto-calibration method configured to calibrate an anemometer of a yaw control system to correct for yaw misalignment, includes collecting wind speed and wind direction data from the anemometer over a plurality of time periods. The method includes determining from the collected data a wind direction compensation signal associated with a plurality of wind speed ranges. The step of determining a wind direction compensation signal includes determining from a plotted performance value, a maximum performance value for each wind speed range and the step of determining further includes correlating the maximum performance value for each wind speed range with the associated average generator speed and plotting the maximum performance wind direction against average generator speed for each wind speed range. The maximum performance wind direction associated with the average generator speed for each wind speed range constitutes the wind direction compensation signal for the wind speed range.
