Steuerungsverfahren für eine zweifach gespeiste Drehfeldmaschine und Maschine, die dieses Verfahren benützt

摘要

The wind turbine is coupled to an electric machine which has a stator (S) with windings (ES) and rotor (R) with windings (ER). The stator is connected to a set of contactors (4) to short-circuit the stator windings or to connect them to the electrical supply network (8). The rotor has a frequency converter (2) connected between the rotor windings and the supply network.
