Abstract
The present invention relates to a method for operating a doubly fed induction generator wind power facility during an OVRT event, said the wind turbine facility being adapted to inject active and/or reactive current into an associated grid, the method comprising the steps of determining the occurrence of an over voltage grid event, and maintaining a grid-side inverter of the doubly fed induction generator wind power facility fully operable during the over voltage ride though event so as to maintain a controllable active and/or reactive current capability during the over voltage grid event.
