    摘要： The present invention relates to a method and a system for operating a Wind Turbine (WTG), which WTG comprises a rotor comprising at least two blades, which blades are pitch regulated, where the rotor is connected to a shaft, which shaft is supported by bearings, and which shaft drives at least one generator, where the WTG uses a load regulation system for regulating the individual pitch of at least two blades. The object of the invention is to compensate for asymmetric load on the rotor in a wind turbine, a second object is to reduce wearing at shaft bearings in the wind turbine, and a third object is to increase the power production of a wind turbine. This can be achieved if the load regulation system measures the actual rotor load by at least one displacement sensor, which displacement sensor is measuring the bending of the main shaft, where the load regulation system based on the shaft bending regulates the individual pitch of the blades for compensating asymmetric load at the rotor.

    摘要： The present invention provides a method of operating a wind turbine including a generator (4) that provides variable voltage at variable frequency and has a stator and a rotor. The wind turbine includes a turbine assembly (2) having at least one blade for rotating the rotor of the generator (4), and a power converter that interfaces the generator (4) to a supply network (NETWORK) operating at nominally fixed voltage and nominally fixed frequency. The power converter includes a generator bridge (10) electrically connected to the stator of the generator (4) and a network bridge (14). A dc link (12) is connected between the generator bridge (10) and the network bridge (14). A filter (16) having network terminals is connected between the network bridge (14) and the supply network. A first controller (18) is provided for controlling the operation of the semiconductor power switching devices of the generator bridge (14). Similarly, a second controller (46) is provided for controlling the operation of the semiconductor power switching devices of the network bridge (14). In response to a change in wind speed (e.g. an increasing or decreasing wind speed) the method comprises the steps of: (i) controlling the second active rectifier/inverter (14) to change the level of power exported out of the dc link (12) such that the dc link voltage changes from a desired level, and (ii) controlling the first active rectifier/inverter (10) to import sufficient current into the dc link (12) through the generator bridge (10) from the generator (4) to restore the dc link voltage to the desired level.

    摘要： It is described a method for setting values of control parameters of a wind farm controller (150) controlling the operation a wind farm (100). The method comprises (A) determining a transfer function (360) between a reference signal (152) for the wind farm controller and a measurement signal (154) being indicative for a voltage level at a PCC (140); (B) recognizing a change of the value of a first parameter (Kd) of the control parameters; (C) varying the value of a second parameter (Ka) of the control parameters; (D) calculating, based on the transfer function, the value of the first parameter, and the value of the second parameter, for a reference signal change (582) being virtually applied to the wind farm controller (150) a virtual response function (584) of a virtual voltage level at the PCC; (E) determining, based on the virtual response function, whether an operational control of the wind farm with the value of the first parameter and the value of the second parameter would lead to a sufficient of the voltage level at the PCC. If the stability is sufficient, (F1) storing the values of the first parameter and the second parameter in the wind farm controller. If the given grid code requirements are not fulfilled, (F2) repeating step (C). It is described a corresponding device and a corresponding computer program as well as a system comprising such a device.
