Description
zum Synchronpunkt und durch das Einrücken der Kupplungen 2,6,10.to the synchronization point and by engaging the clutches 2,6,10.
Bei allen Funktionswechseln bleiben die Motor-Generatoren mit der ihnen einmal zugeordneten Drehrichtung am Netz.With all function changes, the motor-generators remain with the one assigned to them Direction of rotation on the network.
Da die Funktionswechsel immer über den Betriebs-" zustand »Phasenschieber« des Motor-Generators erfolgen, bleibt es freigestellt, den Betriebszustand »Phasenschieber« zu belassen, in dem sowohl die Kupplungen 2,6,10 als auch die Kupplungen der Wandler 4, 8, 12 in ausgerückter Lage gehalten werden.Since the function change always takes place via the "phase shifter" operating state of the motor generator, it remains free to leave the "phase shifter" operating state in which both the Clutches 2, 6, 10 and the clutches of the converters 4, 8, 12 are held in the disengaged position will.
