Controlling the amplitude modulation of noise generated by wind turbines

Controlling the amplitude modulation of noise generated by wind turbines

A method (100) for controlling the amplitude modulation of noise generated by a wind turbine (10) is disclosed. The method (100) may generally include determining an angle of attack (54) of a rotor blade (12) of a wind turbine (10) and maintaining the angle of attack (54) at a substantially constant...

Zusammenfassung:A method (100) for controlling the amplitude modulation of noise generated by a wind turbine (10) is disclosed. The method (100) may generally include determining an angle of attack (54) of a rotor blade (12) of a wind turbine (10) and maintaining the angle of attack (54) at a substantially constant value during rotation of the rotor blade (12) in order to reduce the amplitude modulation of the noise generated by the wind turbine (10).
