摘　　要：根据开关磁阻电机的特性建立了储能飞轮的数学模型,采用Matlab/Simulink仿真分析了系统最大允许电流和电机开断角对系统控制性能的影响。设计了系统充放电控制方式,仿真结果表明,采用电流斩波与角度位置相结合的速度电流双闭环控制方式进行充电控制,采用电流斩波控制的电压电流双闭环控制方式进行放电控制,系统充放电过程具有响应速度快、稳态精度高的特点。最后通过仿真验证了开关磁阻式储能飞轮用作不间断电源的可行性。A mathematical model was developed for a flywheel system based on the characteristics of a switched reluctance motor(SRM)and simulated under a Matlab/Simulink environment.The influence of the maximum permissible current and the breaking angle on the system performance was analyzed.Based on the analyses,a control mode of charging and discharging of the system was designed.During charging,the current chopper control and angle position control were adopted;whereas in discharging,the current chopper control was adopted.The simulation results showed that the charging and discharging processes had the characteristics of a fast response speed and a high steady state precision with the proposed control method.Finally,the feasibility of using SRM based flywheel as an uninterruptible power supply was verified by simulation.
