摘要： A harmonic predictor for a wind farm comprising at least two wind turbines, each having a generator with a converter for generating electrical energy. The harmonic predictor determines the harmonic component expected from the wind farm in order to limit the harmonic component to a harmonic limit. The harmonic predictor comprises a calculation module, an iteration module and a summing module. The calculation module calculates a complex mean value over at least one period of the harmonic component of one of the wind turbines and determines a first equivalent vector therefrom. The iteration module successively connects the calculation module to at least one other of the wind turbines to form at least one second equivalent vector. The summing module sums the equivalent vectors to form a total vector and compares the total vector with the harmonic limit.

摘要： The invention relates to a wind turbine having a rotor (12), a generator (14) driven by the rotor, a converter (15), and a control device (167), which has an input for a control signal for reactive power output and a controller (72) for the converter (15). The controller (72) determines a reactive power target value for the wind turbine and corrects the output reactive power in dependence on the voltage present at the wind turbine. The invention provides for an additional module (8) for the controller (72), which additional module has separate small and large signal paths (81, 82) and interacts with the controller (72) in such a way that the small signal path (81) has an additional storage element (83) in comparison with the large signal path (82), which additional storage element stores state values of the small signal path (81) for the past. Thus, small voltage changes can be reacted to more slowly and while taking into account past values, whereas large changes can be reacted to quickly, in particular in the event of a network short circuit.
