摘要
车载牵引变流系统作为高速列车的动力源,其安全可靠性对保障高速列车安全、高效、可靠的运行和维护至关重要。在非线性、强耦合和多工况等复杂条件和恶劣环境中长期运行,牵引变流系统中的各类部件都会出现不同程度的劣化失效,引发各类故障,给高速列车的安全运行带来极大挑战。为此,针对高速列车车载牵引变流系统功率器件、牵引控制单元、传感器和中间直流环节等故障率高的部件进行了故障诊断与容错控制方法的调研和总结,对比分析不同方法的研究思路和适用条件。最后,讨论车载牵引变流系统故障诊断与容错控制研究中亟待解决的问题,并对未来的研究做出展望。
As the driving source of high-speed trains,the vehicular traction converter system is critical to ensuring their safe,efficient and reliable operation and maintenance.In the long-term operation under complex conditions and harsh environments such as nonlinearity,strong coupling,and multiple operating conditions,various components in the traction converter system may encounter different degrees of deterioration failure,causing various types of failures and further affecting the safe operation of high-speed trains seriously.With regard to this,the fault diagnosis and fault-tolerant control methods for the components with a high failure rate in the vehicular traction converter system of high-speed trains,including power devices,traction control unit,sensors,and intermediate DC-link,are investigated and summarized in this paper.Moreover,the research ideas and applicable conditions for different methods are compared and analyzed.Finally,some open problems and challenges in the research of fault diagnosis and fault-tolerant control of the vehicular traction converter system are discussed,and the promising research directions are pointed out.
