Design of Switched Reluctance Generator Control System for Flywheel Energy Storage

In terms of the unstable output voltage and low power density during the power generation process of the flywheel energy storage system(FESS), a control scheme of an improved flywheel energy storage system is studied. The motor in the system uses the three-phase 12/8 Pole switched reluctance generator(SRG), and integrates the motor’s rotor with the rotor of the flywheel energy storage system. The Hall position state and working principle of the switched reluctance motor(SRM) during power generation are explained in detail. Angle position control (APC) and pulse width modulation (PWM) control are added on the basis of current chopping control (CCC). It overcomes the problems of large output voltage pulsation and low power density when the motor is running at low speed, and the feasibility of the above method is verified through simulation and experiment.
