Speed-adjustable Motor-generators for Pumping Storage Stations
For pumping storage stations with wide rangeability of head and discharge, a speed-adjustable motor-generators can be used for improving operation condition. The paper introduced various speed adjustment modes including pole-change, frequency-change at stator side, dual stators and AC excited motor-generator and reviewed them respectively. At last, the application prospect of speed-adjustable motor-generator is given.
