Abstract
A yaw auto-calibration method configured to calibrate at least one anemometer of a yaw control system to correct for yaw misalignment. The yaw auto-calibration method includes collecting wind turbine data over a plurality of time periods with respect to the at least one anemometer. The wind turbine data including one or more of mechanical speed, wind speed, turbine power, and wind direction. The method includes determining from the collected data a wind direction compensation signal associated with a plurality of operational parameter ranges and the wind direction compensation signals correspond to the effects on the at least one anemometer due to yaw misalignment. The method further includes providing the wind compensation signals to the yaw control system to adjust the wind direction data of the at least one anemometer for each of the associated operational parameter ranges.
