Method and apparatus for wind turbine noise reduction
Abstract:
A method for operating a horizontal axis wind turbine is provided, the wind turbine including: a rotor including a rotor blade, wherein the rotor is rotatably coupled to a nacelle, and the rotor is rotatable about a horizontal rotor axis extending through the nacelle, and the nacelle is rotatably coupled to a tower, the nacelle rotatable in a yaw plane about a yaw axis. The method includes determining a wind direction; determining a yaw angle setting, wherein the yaw angle setting deviates from an alignment of the rotor axis and the wind direction in the yaw plane; yawing the nacelle to the yaw angle setting; and operating the wind turbine for example to generate electricity.
