Abstract:
A method for controlling noise generated from a wind turbine. The method including providing a blade attached to a hub having a rotor shaft, and a generator in communication with the rotor shaft. The at least one blade includes an adjustable pitch angle. The method further includes providing a wind turbine acoustical profile and a wind turbine power profile. The wind turbine acoustical profile and the wind turbine power profile are compared to determine a noise reduced operational condition. The wind turbine is controlled to provide a rotor speed and the pitch angle of the blade corresponding to the noise reduced operational condition.
