开关磁阻发电系统的故障分析及仿真

对开关磁阻电机在发电运行模式下的各种典型故障进行了分析研究,利用Matlab/Simulink中的电力系统工具箱对开关磁阻发电机系统进行建模,通过对模型施加不同的故障条件,仿真了系统在负载故障、功率变换器故障、电枢绕组开路/短路等故障下的电压、电流输出波形.通过对结果的分析可以看出,开关磁阻发电系统具有较高的容错性能,当发生缺相故障时,系统仍能维持正常的电压输出.同时,这种故障的建模和仿真也为开关磁阻发电系统的故障诊断和容错研究提供了一种可行的方法.

Fault Analysis and Simulation for the Switched Reluctance Generator System

This paper studies the principle of a switched reluctance generator(SRG) system, and presents an comprehensive analysis of the SRG's faults.A model,including the switched reluctance machine,power converter,controller,excitation source,and load,is established using Matlab/Simulink/PSB toolbox to investigate the system's output under various fault conditions such as load fault,converter switch fault,phase windings fault,and so on.The simulation results indicate that the SRG has a better fault-tolerant capability,since that the output voltage can keep a normal value when the SRG is lacking a phase.The modeling and simulation method used in this paper can also be applied in fault diagnosis and fault-tolerant analysis for the SRG.
