摘要
一级负荷(自闭)贯通供电系统作为铁路供电系统的重要组成部分,其供电系统的稳定性直接决定了高速(普速)铁路的安全运行程度,因此一级负荷(自闭)贯通线路的运行状态和发生故障时的精确定位显得极为重要。根据行波的特性,通过分析故障状态下行波传输的波过程,实现基于故障状态下行波波形的铁路一级负荷(自闭)贯通线路故障点精确定位,并通过具体案例理解行波定位对运行线路故障排查的重要性。
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.
