WIND ENERGY SYSTEM
The invention relates to a wind energy system having a support (5), a rotor (6) that is rotatably supported on the support (5) about a rotor axis (7), said rotor having multiple rotor blades (9, 10) and being driven or drivable by means of wind energy (15), an electric generator (16) that is coupled to the rotor (6), said generator being drivable or driven by the rotor (6), a first converter (23) that is electrically coupled to the generator (16), said converter being coupled or capable of being coupled to an electric distribution network (27), at least one electric or partially electric auxiliary system (20), wherein the at least one auxiliary system (20) is or can be electrically coupled to the generator (16) while interconnecting a second converter (33).
