| 摘 要： | 提出了一种适用于超长距离铁路自闭贯通线路故障定位的方法,通过将输电线路分段,首先确定故障所处的分段,然后在各段内实现精确故障定位.Matlab/Simulinl仿真验证了该方法的可行性.仿真结果表明本文提出的故障定位原理理论上可以满足对单相接地故障进行较为精确的定位.

| Abstract: | A novel fault location method for very-long-distance line of electrical distribution networks of railway is proposed in this paper. Fistly, the distribution line of railway is separated to four parts. Secondary, the algorithm of fault location based on the equivalent circuit is used to locate the fault position in each part. Simulations are performed to verify the proposed method. The results show that the proposed method can meet the requirements of the precision of the very-long-distance line of electrical distribution system of railway. |
