摘要
针对串联补偿装置位于线路中间的情况,给出了一种基于双端量的串联补偿线路单相接地故障测距方法。该算法计及了故障过程中金属氧化物变阻器(MOV)的动作情况对线路实际阻抗值的影响,在无需知道串联补偿装置的相关参数和其具体工作状态条件下,就能准确地实现串联补偿线路的故障测距。利用EMTDC/PSCAD和MATLAB软件进行了仿真实验,实验结果验证了算法的有效性。
A single-phase grounding fault location algorithm based on dual terminal variables is proposed for the line with series compensation device installed in the middle,which considers the effect of MOV（Metal Oxide Varistor） on the actual line impedance during the fault and precisely locates the fault without the relevant parameters and operating state of series compensation device. The validity of the proposed algorithm is verified by the results of simulation with EMTDC / PSCAD and MATLAB.
