摘要： A method for supplying an excitation current to an excitation winding of a rotor of a three-phase generator of a system for producing a three-phase alternating voltage to be fed into a power network. A pulsed excitation current is supplied to the excitation winding if a rotational frequency of the rotor deviates from a network frequency of the power network.
