摘　　要：本文针对开关磁阻电机的严重非线性特点,利用有限元软件分析了一种2.2 kW的三相(12/8)开关磁阻电机的电磁场,并根据得到的磁化曲线、电感曲线以及转矩曲线结合Simulink建立了开关磁阻电机起动和发电过程的非线性模型,联合得到航空高压直流起动/发电机系统的模型,得到了仿真波形。通过分析表明了该模型能很好的模拟航空高压直流起动/发电机的运行过程,从而为下一步航空高压直流电源系统的特定分析提供了一种可行的研究方法。Considering the nonlinear characteristics of Switched Reluctance Motor （ SRM）, this paper analyzed the electromagnetic field of a 2.2 kW of three phase SRM （ 12/8 ） by using finite element software. With the magnetization curve, the inductance curve and torque curve analyzed by the finite element software, the nonlinear simulation model of aeronautic high voltage direct current starter/generator system was estab- lished by Simulink. Through the analysis, the results showed that the running process of aeronautic high volt- age direct current starter/generator could be well simulated by the model and a research method was provided for the analysis of the aeronautic high voltage direct current power system.
