摘　　要：电力电缆由于其独特的优越性,在煤矿供电中被广泛地采用,但电缆故障也随之增多。以零序直流原理为基础建立了基于直流分量的电缆测距等效电路模型,免去了对复杂的交流量及其干扰的分析,大大简化了分析处理过程。通过MATLAB电力系统仿真软件建立了多分支电缆模型,并将仿真数据用于神经网络的训练;通过仿真验证了此测距策略的可行性和有效性。Due to its unique advantages,power cable has been widely adopted by coal mine power supply,but its fault is also increased. Since the laying position of most cable is more subtle,the detection of fault point has become more difficult. This paper which is based on zero sequence DC theory established a cable distance equivalent circuit model based on the DC component,with which could eliminate the need for complex AC and its interference analysis and simplify the analysis process greatly. In this paper,a multi branch cable model is built by Sim Power Systems in MATLAB and the simulation dates are used in training neural network. Finally,verified the feasibility and validity of the measurement scheme by the simulation results.
