    Abstract: A method for controlling a wind farm includes: receiving temperature data associated with a plurality of locations along a sound path between the wind farm and a sound immission point from one or more sensors; estimating a propagation characteristic of the sound path based at least in part on the temperature data; predicting a noise level at the sound immission point based at least in part on the propagation characteristic; determining a control signal for one or more wind turbines in the wind farm based at least in part on the noise level; and using the control signal to control the one or more wind turbines.

    Abstract: A wind turbine blade includes a trailing edge including a radially inboard portion and a radially outboard portion opposite the radially inboard portion and a retrofit system coupled to the trailing edge. The retrofit system includes a mounting structure for coupling the retrofit system to the trailing edge and at least one serrated portion extending at least partially along the mounting structure. The serrated portion includes at least one substantially acoustically absorbent material. A method for reducing noise emission from a wind turbine blade including a trailing edge and retrofit system is also disclosed.

    Abstract: A wind blade is provided that includes a primary blade body defining a leading edge and a trailing edge and further defining a pressure side and a suction side joining along the trailing edge. The wind blade also includes a secondary blade having an aerodynamic contour defining a first surface and a second surface and coupled with the primary blade body for the purpose of shielding noise. The secondary blade body is disposed proximate to at least a portion of the trailing edge on at least one of the pressure side and the suction side of the primary blade body and may also improve overall performance of the wind blade.

    Abstract: Rotor blade assemblies for wind turbines and methods for reducing rotor blade noise are disclosed. A rotor blade assembly includes a rotor blade having external surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge extending between a tip and a root. The rotor blade further defines a span and a chord. The rotor blade assembly further includes a tab. The tab includes an inner surface, an outer surface, a forward end and an aft end. The inner surface is mounted to one of the pressure side or the suction side. The outer surface has a cross-sectional profile configured to modify an operational value of the rotor blade at the trailing edge. The forward end is disposed within the chord.
