Abstract: A wind turbine blade assembly includes a rotor blade having exterior surfaces defining a pressure side, a suction side, a leading edge and a trailing edge, each extending between a blade tip and a root. The rotor blade additionally defining a span and a chord. The blade assembly further includes a plurality of micro boundary layer energizers positioned on a surface of the pressure side of the rotor blade. The plurality of micro boundary layer energizers extending one of above or below a neutral plane of the rotor blade. The micro boundary layer energizers are shaped and positioned chordwise to delay separation of a boundary layer at a low angle of attack. A wind turbine including the blade assembly is additionally disclosed.

Abstract: The present disclosure is directed to a system and method for reducing noise associated with a wind turbine, more particularly fan noise when the wind turbine is operating under a reduced noise operating mode. More specifically, the method includes operating the wind turbine at a predetermined rotor speed that is associated with a predetermined power output. The method also includes receiving a request to operate in a reduced noise operating mode and in response to the request, reducing the predetermined rotor speed so as to provide a reduced power output. In response to reducing the predetermined rotor speed, another step includes reducing a speed of one or more cooling fans of the wind turbine.
