摘　　要：煤矿供电系统复杂,串联供电级数多,越级跳闸现象频发,严重影响煤矿安全。提出了一种煤矿智能供电系统区域集控式故障识别与隔离方案,为提高故障定位的准确性,对以往的矩阵算法作了改进,并重点对算法的容错性进行了分析,最终得到适用于煤矿供电系统的矩阵算法,可大大提高故障定位与故障隔离的准确性和快速性。Coal mine power supply system is complex, collusion series; go tripping frequent phenomenon,the serious influence of coal mine safety. Puts forward an intelligent coal mine power supply system regional integration type fault identification and isolation. In order to improve the accuracy of fault location, the previous matrix algorithm is improved, and the key to the algorithm of fault tolerance are analyzed, finally be matrix algorithm is applicable to coal mine power supply system, can greatly improve the accuracy of fault location and fault isolation and power.
