摘要： The invention relates to an arrangement (10) to reduce noise of a wind turbine rotor blade (20), wherein the arrangement (10) comprises a wind turbine rotor blade (20) and a noise reduction means. The noise reduction means comprises a serrated extension (41) for at least reducing noise which is generated from the wind turbine rotor blade (20), and the noise reduction means is attached to the trailing edge section (27). The serrated extension (41) comprises a number of first teeth (61) and a number of second teeth (62). The design of the first teeth (61) and the design of the second teeth (62) are differently compared to each other such that suction side noise, which is generated at a suction side (34) of the wind turbine rotor blade (20), and pressure side noise, which is generated at a pressure side (33) of the wind turbine rotor blade (20), are both reduced by the teeth (61, 62) of the serrated extension (41). Advantageously, the first teeth (61) and the second teeth (62) are arranged in an alternating, periodic pattern and differ from each other by an angle of inclination (43) with regard to a trailing edge streamline (42) and or by its planform shape. Furthermore, the invention relates to a method to reduce noise of a wind turbine rotor blade (20).

摘要： The invention relates to a method for wind turbine generators for reducing electrical disturbances in the form of power variations which are caused by damping controllers arranged the compensate structural oscillations by inducing shaft torque variations. The shaft torque variations are generated by imposing corresponding variations in a generator set-point, e.g. a power or torque set-point. Variations in the generator set-point cause undesired variations in the power injected to the grid by one or more wind turbine generators. According to an embodiment of the invention the electrical disturbances may be reduced by limiting a damping controller's control action. The amount of limitation or restriction of the damping controller may be determined on basis on electrical disturbance information determined from power measured e.g. at a location on the grid.

摘要： An assembly is provided of, firstly, an aerofoil-shaped body, such as a wing of an airplane or a rotor blade of a wind turbine, having a trailing edge and, secondly, a noise reducing serration extending along at least part of said trailing edge. The serration comprises a base plate defining a first edge connected to the aerofoil-shaped body near to said trailing edge and a second edge having attached thereto a number of teeth defining tips facing away from the base plate. The base plate is located behind the trailing edge and is separated therefrom by a gap wherein the connection between the base plate and aerofoil-shaped body is defined by at least one tape-like member made of a material which allows the tape-like member to bend, stretch and buckle. The serration in such a manner is stiff against bending but weak against torsion that in a range of expected operational loads the serration is not able to bend substantially, whereas in said range of expected operational loads the base plate is able to twist.
