METHOD FOR CONTROLLING THE FEEDING OF ELECTRICAL POWER OF A WIND TURBINE INTO AN ALTERNATING-CURRENT NETWORK

摘要

In order to avoid overvoltages and/or irregular power flows after a network disturbance has been rectified in a method for controlling the feeding of electrical power of a wind turbine into an electrical alternating-current network connected to the wind turbine, the current is set to zero when the network voltage returns to the target range of the network voltage at least until the phase angle of the current with regard to the returned network voltage is set to a value intended for normal operation.
