环网中输电线路故障点的定位算法

A Fault Location Algorithm for Transmission Lines in Circle Network

提出了环形电网中输电线路的故障点定位法，该法使用本地信息，定位精度不受负荷电流、过渡电阻和故障线对侧系统阻抗变化的影响。数字仿真结果令人满意。

A fault location algorithm for transmission lines in circle network is presented.The algorithm uses local data. Its location accuracy is independent of power # flow, transient resistance and variation of remote system impedance. Simulation results are satisfactory.
