| 摘 要： | 基于模分量分析，提出了自故障线路两端仅利用本地信息准确定位短路点的实用方法。短路过渡阻抗、线路分布电容和对侧系统运行阻抗等因素对新算法测距精度影响较小，且故障线路两侧之间不需通信联系、不受通信技术条件限制，测距方程不存在伪根问题。同时指出，基于双侧电源线路模型的测距算法一般不能直接用于环网中的线路故障测距。

| Abstract: | Based on the modal analysis,the practical fault location scheme,using local terminal data to estimate fault distance from itself end respectively,is proposed.The locating fault accuracy is almost insensitive to shunt capacitance,transient impedance and remote source impedance.The new technique does not require real communication between two ends,and has no false root generally.Meanwhile,it is proposed that the fault location algorithm based on two terminal line model is not suitable for these lines operating in circle high tension. |
