摘要
针对线路结构及参数对阻抗法二次故障定位结果产生的影响,并且为了进一步了解各种因素可能导致的定位误差范围,本文采用MATLAB分别对相间短路故障定位的线路长度、分支负荷、变电站母线其他线路三个因素,对其逐一进行故障定位有效性和准确性的敏感性分析。最后得出相间短路故障定位的主要因素为分支负荷容量,分支负荷容量越大,故障定位距离的误差越大。
In view of the influence of the circuit structure and parameters on the secondary fault location of the impedance method, and in order to further understand the possible range of positioning error caused by various factors, In this paper, we use MATLAB to analyze the sensitivity, accuracy and accuracy of fault location, and to analyze the three factors of line length, branch load and other lines of substation bus. Finally, the main factors that lead to the fault location are the branch load capacity, the greater the branch load capacity, the greater the error of the fault location distance.
