摘　　要：煤矿中大量大功率电气设备的投入运行,导致煤矿拓扑结构复杂、线路过负荷、电能损耗严重。针对此问题,本文以煤矿供电系统为研究对象,改进传统分层前推回代潮流算法,节点分层配电网逻辑拓扑图,明确煤矿配电网拓扑结构,并分别从末梢节点和源点开始进行前推回代计算,根据得到的功率损耗与电流电压数据分析煤矿供电系统电能损耗与功率因数,计算无功补偿容量,得到功率损耗与电流电压数据,并分析煤矿供电系统电能损耗与功率因数,判断是否需要无功补偿并计算无功补偿容量,这有利于提高供电系统稳定性,减少煤矿企业电能损耗。The operation of a large number of high-power electrical equipment in coal mines has led to complex topology structures,overloaded lines,and severe energy losses.In response to this issue,this paper takes the coal mine power supply system as the research object,improves the traditional layered forward and backward power flow algorithm,and clarifies the topology structure of the coal mine distribution network through the logical topology diagram of the node layered distribution network.Starting from the terminal nodes and source points,forward and backward calculation is carried out separately.Based on the obtained power loss and current voltage data,the power loss and power factor of the coal mine power supply system are analyzed,and the reactive power compensation capacity is calculated,obtain power loss and current voltage data,analyze the power loss and power factor of the coal mine power supply system,determine whether reactive power compensation is necessary,and calculate the reactive power compensation capacity,which is conducive to improving the stability of the power supply system and reducing the power loss of coal mining enterprises.
