摘要
为解决传统动车组主变流器维修模式的缺陷,引入故障预测和健康管理技术对动车组主变流器维修进行设计研究,探讨了基于HMM模型+小波分析的主变流器故障预测与健康管理的故障诊断原理,通过仿真研究建立了MATLAB仿真模型,验证上述方法是可行的。
In order to solve the defects of traditional EMUs traction converter maintenance mode,converter prognostic and health management technologies were introduced.The principle of the fault diagnosis of prognostic and health management of traction converter based on HMM model and wavelet analysis method was discussed,and the MATLAB simulation model was built and researched,which verified the feasibility of the methods.
