SYSTEM AND METHODS FOR REDUCING WIND TURBINE NOISE

摘要

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).
