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 80 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 destructive faults.The research results indicate that SRG has a better fault-tolerant capability and is applicable to the main source of electrical power of MEA.The modeling method and simulation results of fault have certain reference value to fault diagnosis and faulttolerant research of SRG systems.
