Abstract: A method for mitigating noise during high wind speed conditions of a wind turbine includes providing a backward twist to the outboard region of the rotor blade having an angle of less than 6°. The method may also include reducing a tip chord taper within at least a portion of the outboard region of the rotor blade. Further, the method may include increasing a local tip chord length of the rotor blade. In addition, the method may include increasing a torsional stiffness of the outboard region of the rotor blade. As such, a combination of one or more of the blade properties described above are configured to reduce noise associated with high wind speed conditions.

Abstract: A wind turbine includes a hub configured to rotate about an axis at a first rotation speed and at least one blade coupled to the hub. The wind turbine also includes a sensor assembly configured to detect at least one characteristic of wind flowing through the wind turbine. The sensor assembly is mounted to the hub. The sensor assembly includes a laser device configured to emit a laser beam and at least one optical element configured to direct the laser beam. The sensor assembly also includes a non-motorized mechanism configured to rotate the at least one optical element at a second rotation speed when the hub rotates at the first rotation speed. The second rotation speed is greater than the first rotation speed.

Abstract: The present disclosure is directed to a blade sleeve for a blade tip of a rotor blade of a wind turbine. The blade sleeve includes a rapid-prototyped body having a pressure side, a suction side, a first open span-wise end, a closed leading edge, and a trailing edge. Further, the body is slidable onto the blade tip of the rotor blade. In addition, the blade sleeve includes at least one additional rapid-prototyped feature integral with the body.

Abstract: A rotor blade assembly for a wind turbine is presented. The rotor blade assembly includes a rotor blade having a surface, where the surface of the rotor blade includes an inclined groove. The rotor blade assembly further includes at least one add-on element mounted on the surface of the rotor blade via a bonding interface downstream of the inclined groove such that particulate matter in an airflow upstream of the at least one add-on element is deflected away from the bonding interface between the surface of the rotor blade and the at least one add-on element. The wind turbine having the rotor blade assembly is also presented.

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 first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. Each of the blade segments having a pressure side shell member, a suction side shell member. The blade further including a coupling component extending spanwise and structurally connecting the first blade segment and the second blade segment. A thermal actuation component is coupled to the coupling component and passively actuated in response to a change in thermal conditions so as to provide for aeroelastic tailoring and pitch control to the wind turbine blade.

Abstract: A wind turbine blade includes a first blade segment and a second blade segment extending in opposite directions from a chord-wise joint. The first blade segment includes a beam structure extending lengthways that structurally connects with the second blade segment at a receiving section, wherein the beam structure forms a portion of an internal support structure and includes a shear web connected with a suction side spar cap and a pressure side spar cap. The present technology also includes a joint rod located at a first end of the beam structure for connecting with the receiving section of the second blade segment to form a coupling joint about a joint axis. The coupling joint is coupled to an adjustable elastic support. The receiving section may further include a torque coupling positioned offset from the joint axis, such that a bending motion of the beam structure automatically induces a twist motion. A method of assembling the wind turbine blade is additionally disclosed.

Abstract: A wind turbine includes at least one blade having a pressure side, a suction side, a leading edge, and a trailing edge that define an airfoil-shaped profile. The suction side and/or the pressure side has a morphable region. The wind turbine also includes a control system configured to activate the morphable region to alter the airfoil-shaped profile and reduce negative lift generated by the blade when the blade is oriented at a negative lift angle.

Abstract: A rotor blade assembly of a wind turbine includes a rotor blade having an aerodynamic body with an inboard region and an outboard region. The inboard and outboard regions define a pressure side, a suction side, a leading edge, and a trailing edge. The inboard region includes a blade root, whereas the outboard region includes a blade tip. The rotor blade also defines a chord and a span. Further, the inboard region includes a transitional region of the rotor blade that includes a maximum chord. Moreover, a chord slope of the rotor blade in the transitional region ranges from about −0.10 to about 0.10 from the maximum chord over about 15% of the span of the rotor blade.
