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.

A method for controlling noise generated from a wind turbine having a blade attached to a hub having a rotor shaft, and a generator in communication with the rotor shaft, and the at least one blade having an adjustable pitch angle, the method comprising:
- providing a wind turbine acoustical profile;
- providing a wind turbine power profile;
- comparing the wind turbine acoustical profile and the wind turbine power profile to determine a noise reduced operational condition;
- and
- controlling the wind turbine to provide a rotor speed and the pitch angle of the blade corresponding to the noise reduced operational condition.
A wind turbine, comprising:
- at least one blade operably mounted on the wind turbine, the at least one blade attached to a hub having a rotor shaft, the rotor shaft in communication with a generator, the at least one blade having an adjustable pitch angle;
- the generator configured for converting torque into electrical power;
- and
- a controller capable of comparing a wind turbine acoustical profile and a wind turbine power profile to determine a noise reduced operational condition, the controller further being capable of controlling the wind turbine to provide a rotor speed and the pitch angle of the blade corresponding to the noise reduced operational condition.
