Abstract
A method for reducing noise of a wind turbine includes monitoring, via one or more sensors, a wind speed at the wind turbine. The method also includes determining, via a turbine controller, a nominal wind direction for producing rated power of the wind turbine. Further, the method includes determining a pitch angle of at least one rotor blade of the wind turbine. As such, the method includes determining a yaw offset for a nacelle of the wind turbine based on the wind speed and/or the pitch angle. Thus, the method further includes changing a yaw angle of the nacelle by the yaw offset when the wind speed exceeds a predetermined threshold so as to reduce noise of the wind turbine.
