采用附加低频电源法监测矿井低压供电电缆漏电情况，其监测结果容易受到电缆对地电容变化的影响。为消除电容影响，提高监测的可靠性，通过Simulink建立分支电缆单相漏电模型。对分支电缆增设对地可调电感以进行容性电流补偿，并且在低频电源处增设总支路监测模块。仿真结果表明，改进的附加低频电源监测法提高了监测数据的准确性。

The monitoring of leakage occurring in mine low-voltage power supply cable by additional low-frequency power threatens to leave the monitoring results vulnerable to the impact of changes in cable capacitance to ground. Aimed at eliminating the impact and improving the reliability of leakage monitoring with additional low-frequency power, this paper introduces the way adjustable inductance branch cables is added to compensate for the changes in capacitance and detection on total to ground for branch is also added at the low-frequency power. The simulation results show a greater accuracy in leakage monitoring.
