英文摘要： Considering the problems of the high-speed railway(HSR) traction power supply system(TPSS) that the recession process and service behavior of key equipments is not clear, the system health status is made difficult to assess, and the speed of searching fault components and its reason is slow. The project is put forward to research about “the evolution mechanism of service behavior of key equipments and the diagnosis of system health status in high speed railway traction power supply system”. Through researching the evolution mechanism and influence factors of service behavior of the traction transformer, the catenary, the integrated grounding system, and combining with data inspection and monitoring, the corresponding evaluation index system and simulation platform are established. And then, the evolution law of service behavior of three key equipments can be revealed and assessed. Above this basis, by analyzing coupling relationship among all the equipments, assess the health status of traction power supply system and warn any possible fault in time. Through Revealing the propagation law of equipment different fault modes in system, study the fault inversion method and accurately search fault component and its reason. The project aims to reveal the evolution law of service behavior of the key equipments in high
