摘要
分析了小电流接地系统中一些典型工况的2点异相接地故障的特点,并运用对称分量原理提出了响应的故障测距算法。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,大量的数字防真计算表明,该故障测距算法是可行的。
The characterists of several typical operating conditiongs of two-point earth-fault with different phases in low earth-fault 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 digital simulation calculations indicate that the fault location algorithms are feasible.
