Abstract

In this paper, the mechanical characteristics, charging/discharging control strategies of switched reluctance motor driven large-inertia flywheel energy storage system are analyzed and studied. The switched reluctance motor (SRM) can realize the convenient switching of motor/generator mode through the change of conduction area. And the disadvantage of large torque ripple is weakened in the large inertia load application. It has a certain potential for application in flywheel energy storage systems. For motor mode, the optimal switching angle is established by means of off-line simulation. The maximum output torque is guaranteed and the charging time is shortened by this method. During the discharge process, an online optimal control strategy is used to achieve the optimization of generation efficiency, and the maintenance of the command bus voltage is guaranteed by DC-bus voltage monitoring. The above control strategy is verified by simulation.

开关磁阻电机驱动飞轮储能系统开关角优化的运行控制策略

分析和研究了开关磁阻电机驱动的大惯量飞轮储能系统的机械特性和充放电控制策略。开关磁阻电机(SRM)可以通过改变导通面积来实现电机/发电机模式的便捷切换。在大惯性负载应用中，减小了转矩脉动大的缺点。在飞轮储能系统中具有一定的应用潜力。对于电机模式，通过离线仿真确定了最佳开关角度。该方法保证了最大输出扭矩，缩短了充电时间。在放电过程中，采用在线最优控制策略实现发电效率的优化，并通过直流母线电压监测保证命令母线电压的维持。通过仿真验证了上述控制策略的有效性。
