Abstract :
During startup stage of short-term acceleration system such as continuous shock test, high power induction motor draws dramatically high current in a short time, which would degrade the power quality. Hence, energy storage devices with excellent cycling capabilities are highly desirable and the flywheel energy storage system (FESS) is one competitive choice. This paper presents the control strategies of both synchronous motor and induction motor in flywheel energy storage system. The FESS is based on a bi-directional power converter, and consists of a synchronous motor and a high inertia flywheel. Simulation results demonstrate the time responses satisfactorily during the induction motor startup stage. Meanwhile, the control scheme of charging and discharging stage of synchronous motor in FESS are presented.
