摘　　要：应用实验方法及电弧动态方程研究故障电弧特性，得到了电弧电压零区的一些特征，据此提出了一种输电线路故障定位方法，它仅需要线路单端的测量数据，并可排除故障电阻及电弧等效电抗、线路参数不对称、发展性故障等的影响。仿真计算表明该法是可行的。Experiment method is used to study the characteristics of fault arc. Some features of zero zone arc voltage are obtained. A new algorithm for faultlocation in power transmission lines is described in this paper. The algorithm requires only the data from one terminal and can exclude the influence of faultresistance and itsequivalent inductance, load current and system operationcondition on two sides. Computer simulation is alsopresented.
