WIND POWER PLANT COMPRISING A REACTIVE POWER MODULE FOR SUPPORTING A POWER SUPPLY SYSTEM AND CORRESPONDING METHOD

摘要

The invention relates to a wind power plant comprising a rotor, a generator driven by said rotor and generating and feeding electrical power to a power supply system, and a control unit controlling operation of said plant and comprising a reactive power control module. According to the invention, the control unit comprises a destination device for a minimum security effective power. The plant also comprises a limiting device for limiting the reactive power control module in such a manner that the reactive power is limited to such an extent that the minimum security effective power is still available taking into consideration the available apparent power, thereby making sure that the entire current generated - except for the active current required for the safe operation of the plant - can be fed to the power supply system in order to support the power supply system in the event of a voltage drop
