摘要： A method for reducing extreme loads acting on a component of a wind turbine includes measuring, via one or more sensors, a plurality of operating parameters of the wind turbine. Further, the method includes predicting at least one blade moment of at least one rotor blade of the wind turbine based on the plurality of operating parameters. The method also includes predicting a load and an associated load angle of the at least one rotor blade as a function of the at least one blade moment. Moreover, the method includes predicting a pitch angle of the at least one rotor blade of the wind turbine. In addition, the method includes generating a load envelope for the component that comprises at least one load value for the pitch angle and the load angle. Thus, the method includes implementing a control action when the load is outside of the load envelope.

摘要： The present disclosure is directed to a pitch assembly for coupling a rotor blade to a hub of a wind turbine. In one embodiment, the pitch assembly includes a first pitch bearing having a first outer race and a first inner race rotatable relative to the first outer race via a first set of rolling elements, a second pitch bearing having a second outer race and a second inner race rotatable relative to the second outer race via a second set of rolling elements, and at least one spacer configured axially between and contacting the first and second pitch bearings. Further, at least a portion of the first pitch bearing and at least a portion of the second pitch bearing are axially aligned between the rotatable hub and the rotor blade in a generally span-wise direction.

摘要： The present disclosure is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade having a blade root section and a rigid ring insert. The rotor blade has pressure and suction sides extending between leading and trailing edges. The blade root section includes an end face configured to attach the rotor blade assembly to a hub. Further, the blade root section includes a span-wise end portion defined by inner and outer circumferential components separated by a radial gap. The radial gap includes a first laminate material embedded between the inner and outer circumferential components at a first span-wise depth and a second laminate material embedded between the inner and outer circumferential components at a second span-wise depth. Thus, the rigid ring insert is disposed in the radial gap and embedded between the first and second laminate materials.

摘要： A pitch bearing assembly for a wind turbine including a stiffener is disclosed. The pitch bearing assembly includes an outer race and an inner race rotatable relative to the outer race. The inner race may define an inner circumference and may include a plurality of gear teeth around the inner circumference. Further, the pitch bearing assembly includes a stiffener having a body and at least one gear pinion configured with the body. The body extends at least partially around the inner circumference of the inner race and the at least one gear pinion engages a portion of the plurality of gear teeth. Further, the body remains fixed relative to the inner race while the gear pinions may freely rotate along with the inner race.
