摘要
介绍了基于双端同步采样的输电线路故障定位算法,该算法借助全球定位系统(global positioning system,GPS)技术同步采集线路两端的电压和电流数据,采用分布参数线路模型,精确考虑分布电容对输电线路的影响,并求解非线性方程,实现故障定位;利用MATLAB软件对该算法进行仿真,仿真结果表明该算法不受过渡电阻、故障类型、故障发生地点以及系统运行方式的影响,具有较高的精度。
Fault location algorithm for transmission lines based on synchronized samplings at both ends is presented. The algorithm synchronously collects both voltage data and current data from two ends of lines with the aid of global positioning system （GPS）. It adopts distributed parameter mode] of power lines, accurately considers affect of distributed capacitance on transmission lines and solves nonlinear equations for fault positioning. Matlab is employed to simulate the algorithm, and the simulation result indicates that the algorithm is immune to the affect from transition resistance, fault type, fault position as well as operation mode of system and acquires high precision.
