摘要： A method for controlling the operation of a wind turbine is provided. The method includes receiving, by means of a power controller, an active power reference signal and an active power feedback signal; determining, by means of the power controller and based on the active power reference signal and the active power feedback signal, a first voltage control signal and a power controller frequency signal; determining, by means of a frequency droop gain unit and based on the power controller frequency signal, a second voltage control signal; determining, by means of a theta integrator unit and based on the power controller frequency signal, an actual angle signal being indicative for an actual angle between a rotating dq reference frame and a stationary abc reference frame; and controlling operation of a network bridge based on the first voltage control signal, the second voltage control signal, and the actual angle signal.

摘要： A method for controlling the operation of a wind turbine which includes a mechanical drive train, an electric generator being mechanically connected to the drive train, and a power converter being electrically connected to the generator is provided. The method comprises (a) determining a frequency of an AC output voltage signal provided by the power converter; (b) recognizing, whether there has been a modification of the determined frequency with respect to a previously determined frequency, which modification is larger than a given threshold; (c) if the modification of the determined frequency is larger than the given threshold, changing a power reference signal for the wind turbine; (d) providing the changed power reference signal to a controller of the wind turbine; and (e) controlling the operation of the wind turbine on the basis of the changed power reference signal.

摘要： A control device, method, and computer program for a wind park are provided, the wind park having a plurality of wind turbines for generating electric power, wherein the wind turbines are electrically interconnected by a wind park grid. The control device includes (a) a determining unit for determining whether a wind park load for consuming electric power from the wind park grid is to be enabled, (b) a calculating unit for calculating a power reference value for each of the plurality of wind turbines, the power reference value being indicative of the amount of power which the corresponding wind turbine should produce, and (c) a transmitting unit for transmitting the calculated power reference values to the corresponding wind turbines, wherein, if the determining unit has determined that the wind park load is to be enabled, at least one of the power reference values calculated by the processing unit is negative.
