SYSTEM AND METHODS FOR REDUCING WIND TURBINE NOISE

A method 200 for reducing noise generated by a wind turbine 10 includes measuring 202 a reference temperature (T ref ) of the wind turbine 10. The method also includes regulating 204 a trailing edge 92 surface temperature (T te ) of a trailing edge portion 96 of a rotor blade 24 attached to the wind...

Zusammenfassung:A method 200 for reducing noise generated by a wind turbine 10 includes measuring 202 a reference temperature (T ref ) of the wind turbine 10. The method also includes regulating 204 a trailing edge 92 surface temperature (T te ) of a trailing edge portion 96 of a rotor blade 24 attached to the wind turbine 10. In addition, the method includes measuring 206 the trailing edge 92 surface temperature (T te ). Further, the method includes regulating 208 the trailing edge 92 surface temperature (T te ) to maintain a predetermined temperature differential (T diff ) between the reference temperature (T ref ) and the trailing edge surface temperature (T te ).
