Abstract
The invention relates to a wind energy unit, connected to an electrical 3-phase AC network, comprising a generator with a rotor, provided with a regulator device, whereby the regulator device comprises a first and a second regulation unit. A network voltage analyzer is connected to the regulator device and the electrical 3-phase AC network, by means of which a network fault can be recognized, said network fault being defined as a deviation of the network voltage sinor representation from a given set interval, whereby the second regulation unit takes over control from the first regulation unit in the case of a recognized fault and the first regulation performs the control for a non-faulty 3-phase AC network.
