中文摘要：分析了故障暂态电流行波的基本理论,在此基础上提出了一种新的单端行波故障测距原理,即利用故障线路暂态行波的现代行波故障测距原理,并将其划分为2种运行模式,标准模式下的原理是利用在线路测量端感受到的由本端分闸初始行波浪涌形成的第1个正向行波浪涌与其在故障点反射波之间的时延计算测量点到故障点之间的距离,而扩展模式下是利用在线路测量端感受到的由对端分闸初始行波浪涌透过故障点到达本端时产生的第1个正向行波浪涌与其在故障点反射波之间的时延计算测量点到故障点之间的距离,理论分析和实测波形分析均表明该原理是可行的,并可以同时适用于永久性故障和瞬时性故障,而且不受电压过零故障的影响,在标准模式下还不受线路对端母线反射波的影响,从而克服了现有单端行波故障测距原理所存在的不足。

外文摘要：The generation mechanism of transient travelling waves caused by fault tripping of transmission lines is analyzed, Based on this analysis, a novel principle--new type modern travelling wave based fault location principle is presented. The new type principle can be classified into two independent modes of operation which are called standard mode and extended mode. Theoretical analysis and actual waveform based transient analysis show that the new type principle is feasible, and it can be applied to permanent and transient faults. The new type principle can not be affected by zero crossing faults, and also can not be affected by the bus reflected surges coming from the opposite terminal of the faulty line under the standard mode, so it overcomes the limitations of the existing single-ended travelling waves based fault location principles.
