摘要
分析了小电流接地系统中一些典型工况的两点异相接地故障的特点，并运用对称分量原理提出了相应的故障测距算法。这些算法均不受负荷电流、接地故障电阻和消弧线圈（或电阻）的影响，大量的数字仿真计算表明：该故障测距算法是可行的。
The characteristics of several typical operating conditions of two - point earth -fault with different phases in low earthfault current system are analyzed in this paper, the fault location algorithms based on symmetrical component method are presented.The algorithms can exclude the influences of fault resistance, load current and arc -suppression coil(or resistance). A lot of digitalsimulation calculations indicate that the fault location algorithms are feasible.
