摘　　要：组合起动/发电(IS/G)系统是多/全电飞机(M/A EA)的关键子系统,而开关磁阻电机(SRM)被认为是实现飞机IS/G系统的首选机型。研究了负载对开关磁阻起动/发电(SR S/G)系统电能质量及稳定性的影响。针对多电飞机电气系统的特点,所涉及的负载被划分为三类:传统负载、特殊负载和恒功率负载,给出了突加、突卸负载时SRM的输出电压和相电流曲线。同时,对恒功率负载下系统的稳定性进行了理论分析和仿真验证。Integrated starter/generator （IS/G） system is a key subsystem in more/all electric aircraft （M/A EA）,and switched reluctance machine （SRM） is considered as a prime candidate for IS/G system. In this paper, the effect of the load on the power quality and stability of the switched reluctance starter/generator （SR S/G） system is studied. According to the feature of the power electric system in aircraft, the loads are divided into three groups, namely conventional, special and constant power loads. Many simulation results, such as curves of output voltage and phase current under loading and unloading conditions, are given. Furthermore, the effect of the constant power loads （CPLs） on the system stability is ana- lyzed theoretically and verified by simulation.
