Abstract: Flywheel energy storage is a new technology of storing the mechanism energy,and this paper introduces the principle,structure and working mode of the flywheel energy storage system（FESS）.The core of the entire system is the motor control due to the charging and discharging process all achieved by the flywheel motor.This paper selects permanent magnet synchronous motor（PMSM） as the flywheel motor,and analyses the basic principle of vector control for PMSM and puts forward the charging and discharging strategy,and then adopts vector control method to realize the control of power-driven and power-generation,and with the help of PWM converter to finish the energy flowing between the DC bus and the motor sides.In the charging condition the DC bus supplies the power,and the PWM converter works as an inverter,and the control system drives the PMSM under the speed and current double-closed-loop strategy to accelerate the flywheel and store energy.In the discharging condition,the flywheel slows down because of its high inertia,and the PWM converter works as a converter,and the control system gets energy back to the DC side from motor side under the voltage and current double-closed-loop strategy.Meanwhile,the voltage regulation loop works to ensure that the voltage of the DC side doesn’t fall.To prove the feasibility and validity of the charging and discharging strategy for the FESS,this paper has finished the hardware and software designs based on DSP28335,and also some experiments have been carried out through the experiment platform.The experimental results show that the control strategy achieves good control effect in practical application.Is flywheel energy storage system a competitive solution?A comprehensive review of control strategies of flywheel energy storage system is presented.
