Description
technical field [0001] The invention relates to a method of operation of a wind turbine with a generator driven by a rotor for delivering electrical energy to a high-voltage electric grid, in particular to loads connected thereto. [0002] The invention also relates to a wind turbine for carrying out the method described above, comprising a rotor and a generator connected to the rotor for feeding electrical energy to a high-voltage power grid; the invention also relates to a wind energy plant (wind energy plant) having at least two wind turbines farm). Background technique [0003] In known wind turbines for generating electrical energy from wind energy, a generator with an electrical load (usually a high-voltage power grid) is operated in parallel mode to the high-voltage power grid. During operation of the wind turbine, the non-reactive power provided by the generator can vary according to the current wind speed. This can lead to the situation, for example at the feed po...
