摘要
阐述了开关磁阻发电机(SRG)的发电原理,给出了三相6/4结构SRG的数学模型,利用Matlab工具在Simulink环境下建立了SRG的行为模型,进行了负载突加、负载突卸、缺相等工作状态的仿真分析,验证了模型的合理性。完成了SRG通过汇流条和二次电源加载负载的建模仿真,仿真结果证实了本模型可以作为飞机供电系统仿真模型的一个子系统来分析研究。通过SRG的简化模型进行稳定性分析,用根轨迹和bode图反映了系统的稳定性。建模时不仅考虑了模型的准确性,而且综合了与飞机供电系统中其他设备建模的兼容性和仿真速度等因素。所提出的建模方法和稳定性分析方法对SRG和飞机供电系统的研究都有一定的参考价值。
Principle and equations for switched reluctance generator (SRG) were expounded. A behavioral Simulink model was built. In the simulation, the load was loaded up and cut down from SRG respectively. Simulation results were proposed. SRG's model as a part of aircraft power distribution systems model was designed that could be effectively used for global systems simulation and analysis. Stability analysis method based on SRG's linear model was proposed. Figures of root locus and bode of linear model presented SRG model's stability.
