开关磁阻发电机系统的故障仿真研究

开关磁阻发电机(SRG)系统出现各种故障模式,为研究多电飞机开关磁阻发电系统的容错性能,建立了关于开关磁阻发电机系统的仿真模型,通过对所建模型施加不同的故障条件,研究了系统在功率变换器故障、负载故障、原动机转速异常、电枢绕组开路、短路等故障下的电压、电流输出波形,仿真了故障运行机理,并对其中的破坏性故障进行了规避处理。研究结果表明,开关磁阻发电系统具有较高的容错性能,适合应用于多电飞机主电源系统。所采用的故障通过建模分析方法也为开关磁阻发电系统的故障诊断和容错研究提供了一定参考。

Study on Fault Running of Switched Reluctance Generator System for More-Electric Aircraft

A simulation model of a 6/4 poles switched reluctance generator(SRG) system was built to study the fault-tolerance performance of SRG System for More-Electric Aircraft(MEA).On the basis of this model,several fault conditions such as,converter switch fault,load fault,prime motor fault,phase windings fault and so on,were simulated,and the simulation results including output voltage and phase current were presented.This paper analyzed the mechanism of the fault running and presented some methods to avoid the d...
