摘要
分析了多电飞机开关磁阻发电系统的运行机理,针对开关磁阻发电机(SRG)的特点,应用MATLAB/Simulink中的电力系统工具箱(PSB)建立了开关磁阻发电系统的仿真模型,并详细的介绍了系统模型的内部结构和Simulink/PSB建模方法。利用该模型对发电系统的稳态和动态特性进行仿真,将仿真结果与实测或其它仿真方法的输出进行比较,结果基本一致,验证了系统模型的正确性,从而为多电飞机电源系统的特性分析提供了一种可行的研究方法。
The structure and principle of a More-Electric Aircraft （MEA） power system equipped with a switched reluctance generator （SRG） were investigated, and a novel method for modeling and simulation of the SRG system was proposed. In this generator system, a high performance controller was designed based on the fixed turned-on angle PWM control strategy. The SRG machine, power convertor, excitation source, controller and loads were all modeled and integrated into a SIMULINK/PSB model in order to analyze the generator system＇s outputs both in steady state and in dynamic state. Simulation results verify the validity of the modeling method, and this novel method also offers a new thought for studying the characteristics of the MEA oower system.
