A wind turbine with a rotor and a generator driven by, the rotor generates electrical power and delivers it to a power system. A control unit controlling the operation of the plant includes a reactive-power control module. The control unit includes also a determining device for a safe minimum active power. Furthermore, and a limiting device for the reactive-power control module, wherein the reactive power is limited to such a measure that the safe minimum active power is still available, taking into consideration the available power. As a result, the total current generated, apart from the active current required for the safe operation of the plant, can be fed into the power system as reactive current as backup in the case of a voltage drop. |
