Development of the Converter-Storage System Based on Smart Materials

Kinetic energy storage comprises a set of electrotechnical equipment, including a flywheel, an electrical machine, a semi-conductive converter and auxiliary equipment. At 90-s of the previous century integrated converter-storage systems were investigated. The rotor of the alternator was simultaneously a flywheel. The latest achievements in high-temperature superconductors (HTSC), soft and hard magnetic materials show these devices may be compact and have high coefficient of active volume utilization with low loss level during the energy storage period. The results of the development of basic principles of cylindrical and disc storage-converter systems designing are being presented.
