摘　　要：在煤矿开采过程中,受复杂地质环境影响,矿井的供电线路容易发生过载、短路和过流等故障,从而影响了整体的开采进度。首先,基于WVD(Wigner-Ville Distribution,时频分析方法),提出了一种新的故障定位方法;其次,结合线路运维经验,从线路故障信号采集和故障信号处理出发,在合理应用双端定位方法后,参考故障信号的能量分布和初始故障信号的到达时间,明确了矿山线路的故障位置;最后,经过仿真试验和实际验证,证明了该方法可为矿山供电线路的管理提供数据支持,确保了煤矿供电的安全性。In the process of coal mining,due to the complex geological environment,the power supply lines of the mine are prone to overload,short circuit,and overcurrent faults,which affect the overall mining progress.Firstly,a new fault localization method based on WVD(Wigner Ville Distribution)was proposed.Secondly,based on the experience of line operation and maintenance,starting from the collection and processing of line fault signals,and after the reasonable application of the dual end positioning method,referring to the energy distribution of the fault signal and the arrival time of the initial fault signal,the fault location of the mining line was clarified.Finally,through simulation experiments and practical verification,it was proven that this method can provide data support for the management of mining power supply lines,ensuring the safety of coal mine power supply.
