Traveling Wave-based Fault Location of Railway First Level Load Connection (Self-closing through Line)
The stability of power supply system of the first level load connection directly determines safe operation of the high-speed (universal speed)railway.Therefore,the operation status of the first level load connection (self-closed through line)and the precise location of the fault are very important.According to the characteristics of traveling wave,this paper analyzes the wave process of down-wave transmission in fault state,and realizes the accurate fault location of railway first level load connection (self-closed through line)based on the down-wave shape of fault state,and elaborates the important role of traveling wave location in fault troubleshooting of operating line through specific cases.
