摘要:
A method of forming a wind turbine blade includes forming a fiber-reinforced resin body. The fiber-reinforced resin body includes a fiber-resin matrix formed with, at least partially, at least one of at least one resin/additive mixture produced by mixing at least one first opaque additive within a first quantity of resin and a first layer of fibers having a plurality of pigmented fibers. The pigmented fibers are formed by at least one of impregnating at least a portion of the first layer of fibers with at least one second opaque additive and forming at least one layer of opaque coating over at least a portion of the first layer of fibers. The opaque coating has a third opaque additive.

A method for determining parameters of a wind turbine is disclosed. The method may generally include receiving signals from at least one Micro Inertial Measurement Unit (MIMU) mounted on or within a component of the wind turbine and determining at least one parameter of the wind turbine based on the signals received from the at least one MIMU.
摘要:
A method and system for controlling a wind turbine generator at wind speeds in excess of rated wind speed to detect wind speeds and, at rated wind speed, control generator torque and generator rotational speed to achieve a rated power for the wind turbine generator. As wind speed increases beyond the rated wind speed, one of generator torque or generator rotational speed is increased and the other of generator rotational speed or generator torque is proportionally decreased to maintain the generator power substantially constant at rated power.
摘要:
A system and method for braking a wind turbine includes monitoring rotation of the wind turbine generator rotor. A braking torque is applied to reduce the rotational speed of the rotor at a first setpoint rotational speed. The braking torque is proportionally increased as the rotational speed of the rotor increases beyond the first detected setpoint rotational speed up to a maximum braking torque.
摘要:
A spar assembly for a rotor blade of a wind turbine is disclosed. The spar assembly may generally include a first spar cap and a second spar cap spaced apart from the first spar cap such that a cross-sectional area is defined directly between the first and second spar caps. Additionally, the spar assembly may include a web having a first end disposed adjacent to the first spar cap and a second end disposed adjacent to the second spar cap. The web may be configured such that at least a portion of an inner surface of the web is disposed outside of the cross-sectional area.

A rotor blade for a wind turbine is disclosed. The rotor blade may generally include a body formed at least partially from a core material. The body may generally define a pressure side and a suction side extending between a leading edge and a trailing edge. The rotor blade may also include a plurality of shear members and a plurality of stiffening members. The shear members may generally extend between the pressure and suction sides of the body and may each include a first end and a second end. The stiffening members may be spaced apart around the pressure and suction sides of the body, with each stiffening member being disposed at the first end or the second end of one of the shear members. Additionally, the rotor blade may include a skin extending around an outer perimeter of the body.
摘要:
In one embodiment, a rotor blade includes a tip, a root, and a body extending between the tip and the root. The body has surfaces defining a pressure side, a suction side, a leading edge, and a trailing edge. The body further defines an inboard portion, an outboard portion, and a bend therebetween. The bend is defined such that the outboard portion extends outwardly with respect to the inboard portion. The bend is stiffened to reduce opening of the bend during deflection of the rotor blade.
