摘要
介绍了开关磁阻起动/发电(SRS/G)系统的应用背景,对系统的性能要求进行了描述,并给出了一台30kW开关磁阻电机(SRM)的定、转子叠片结构及尺寸。基于以上工作,对SRM的优化控制方法进行了研究:在起动阶段,SRM运行在电动状态,以平均转矩最大化作为优化目标,对包括解析、数值及浮角在内的三种优化控制方法进行了深入的研究,并对它们的优化结果进行了详细的比较及分析;在发电阶段,SRM运行在发电状态,以特定输出功率下的系统效率最大化作为优化目标,得到了使主功率损耗最小的优化励磁角。
The application background of the switched reluctance starter/generator （SR S/G） system is briefly introduced. The performance requirements of the system are presented, and then the structure and dimensions of an undergoing 30kW switched reluctance machine （SRM） are described. Based on these works, the optimal control strategies of the SRM are studied： on the starting stage of the engine, the switched reluctance machine operates as a motor, the maximization of its average torque is chosen as an optimization objective. Analytic, numerical and floating angle methods of choosing optimal exciting angles are considered respectively and compared with each other in detail. On the generating stage, the switched reluctance machine operates as a generator, the maximization of its efficiency under certain output power rating is chosen as an optimization objective, and the optimal exciting angles to minimize the main losses are obtained.
