This paper describes fixed-frequency variable-speed motor/generators with voltage source converter cascade, which are used in a wide power range between 1MW for wind energy generation and about 400MW in pumped storage power plants. Structure and design criterias of the controls are shown, based on the system equations. The simulation of the whole system with “SABER” shows the behaviour under normal operation conditions and the “ride through” during line faults. This simulation was the basis for the dimensioning of a 30MW 50-16 2/3Hz rail way supply system which was commissioned in February 1995 in Karlsruhe, Germany.
