Abstract: Embodiments herein describe varying the rotor speed based on the current wind speed when operating in a low power mode. Generally, as the wind speed increases above the rated wind speed (i.e., the wind speed at which the turbine is capable of producing its rated or maximum output power), the rotor speed can be reduced thereby minimizing the risk that the turbine experiences smearing or torque reversals. In one embodiment, as the rotor speed decreases, the turbine maintains the ability to ramp to the rated power of the turbine only by pitching in the blades to an optimal blade pitch angle. Thus, upon receiving a request to cease operating in the low power mode, the turbine can increase the output power to the rated power without first increasing the rotor speed.

Abstract translation: 本文的实施例描述了当以低功率模式操作时基于当前风速来改变转子速度。 通常，随着风速增加到额定风速（即，涡轮机能够产生其额定或最大输出功率的风速），可以减小转子速度，从而最小化涡轮机遭受拖尾或风险的风险 转矩反转。 在一个实施例中，随着转子速度的降低，涡轮机仅通过在叶片中俯仰至最佳叶片俯仰角而保持斜坡至涡轮机的额定功率的能力。 因此，在接收到在低功率模式下停止运行的请求时，涡轮机可以在不首先提高转子速度的情况下将输出功率提高到额定功率。

Abstract: 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.
