Analysing the converter requirements for a dual-fed induction machine based flywheel energy storage system

Klumpner, Christian

Abstract

The Dual-fed Induction Machine was used very successfully in wind generators as it allowed full control of the power captured from the wind within a wide relevant rotational speed range around the synchronous speed needing only a low power rated rotor side converter to control the power extraction. Flywheel energy storage is also characterised by the need to operate at a relatively high speed range whereby large amounts of kinetic energy can be stored with a relatively small inertia, whilst operation at low speed is not needed. This paper aims at investigating how the rotor side converter technical specification is influenced depending on the rated power of the flywheel energy storage system and compare the typical converter power losses of a DFIM based flywheel storage with a squirrel cage induction machine that requires the bidirectional converter to process all storage power.
