提出了一种三端传输线单相接地故障的故障定位算法。传统的单端交流电压和电流定位方法不适用于多端系统。因此，故障区段的指示和故障距离的估计是利用安装了故障定位器的终端的三相电流和电压来完成的。给出的故障定位算法由三个子程序组成，分别针对三种类型的故障进行定位。用MATLAB-SIMULINK仿真器验证了所提出的故障定位器的性能。仿真结果验证了该方法在各种故障电阻和故障位置下的定位精度。
This paper presents a fault location algorithm for single phase to ground faults on three terminal transmission lines. The conventional fault location methods, using one-terminal ac voltage and current are not applicable to the multi-terminal systems. So, the indication of the faulted section and fault distance estimation is performed by using three-phase current and voltage of the terminal at which a fault locator is installed. The delivered fault-location algorithm consists of three subroutines designated for three types of fault. A MATLAB-SIMULINK simulator is used to demonstrate the performance of the proposed fault locator. The result of simulation verifies the high accuracy of fault location with various fault resistances and locations.
