Switched reluctance generation control over wide speed range applied to flywheel energy storage system

Due to the characteristics of high reliability, wide speed scope with high efficiency, and low cost, Switched Reluctance Generator (SRG) system is suitable for applications in the field of variable-speed constant-voltage generation, such as wind power generation, flywheel energy storage, electric vehicle, aircraft power generator, etc. In this paper, a nonlinear dynamic model of SRG system is established, including switched reluctance machine and power circuit. Furthermore, a control plan of variable-speed constant-voltage generation is designed, which covers a wide speed range. Simulation results show that the SRG system has favorable dynamic and static characteristics.
