Abstract
A method for controlling a converter of a wind energy installation. The converter is connected to a rotor of a doubly-fed asynchronous generator for feeding electrical power into an electrical grid and comprises a generator-side inverter, a grid-side inverter, and at least one converter regulator for regulating and/or controlling currents emitted from at least one of the inverters to at least one of the generator and the electrical grid. The method includes detecting a change in electrical voltage present in at least one of emitted real currents and emitted reactive currents at one of the inverters, determining whether the detected change corresponds to a predetermined change, and changing nominal values of at least one of real currents to be emitted and reactive currents to be emitted from the other inverter if the detected change corresponds to the predetermined change.
