Abstract:

This paper gives a brief overview of flywheel energy storage research in Tsinghua University over the past 17 years. Technical characteristics of six flywheel testing systems are introduced. Various key technological issues such as stability of flywheel-motor-bearing system, motor and generator designs and charging-discharging control system are discussed. Suggestions are made for future development of industrial flywheel energy storage systems.
