Abstract
Provided is a method for feeding electrical power into an electrical supply network at a network connection point by means of a converter-controlled infeed apparatus, in particular by means of a wind power system. The electrical supply network has a network voltage having a network frequency and a network phase angle rotating with the network frequency and is characterized by a rated network frequency. The infeed is effected by means of a converter operating in a current-impressing manner. An infeed current is generated by the converter with an infeed phase angle rotating with the network frequency for the purpose of controlling the infeed phase angle. A guide angle rotating with the network frequency is predefined. The guide angle has a predefinable lead angle with respect to the network phase angle such that the guide angle lags the network phase angle by the lead angle.
