基于故障电流分布因子的单端故障定位方法
Single terminal fault location method based on fault current distribution factor
摘要
Abstract
In order to achieve precise positioning of power cable,a single terminal fault location method based on the fault current distribution factor is proposed in this paper.According to the Kirchhoff theorem of voltage,the expression on power system equivalent model is established.Then,the positive sequence,negative sequence and zero sequence components of single terminal three-phase vohage and current from one end of the line are detected.After that,the fault current distribution factor is introduced,and the fault current is replaced by the weighting coefficient of the fault type and increment value of fault current.Finally,the fault location function is established and the fault distance is detected.Simulation results show that the proposed method has strong robustness and high accuracy.关键词
