中文摘要: 本文分析了输电线路相间短路(包括两相接地)故障点定位的一种算法,并给出了一种鉴别故障点真实距离的方法.计算机离线计算表明:本算法测距准确,计算简单,且不受故障点过渡电阻的影响,当对侧系统阻抗的实际值与算法计算时的设定值有偏差时,不影响测距精度.
Abstract:This paper presents a method, that locates the fault point at the transmission line with short circuited two phases and measures the fault distance. The computer analog shows that the measured fault distance is correct and the calculation process is simple. The measured distance is not affected by the transition resistance. If there is differencc between the impedance of the power system and the impedance assumed in the computer analog, the influnce on accuracy of measuring fault distance will not be big.
