摘　　要： 针对煤矿企业用电负荷特征,提出了煤矿混合直流供电系统电压等级序列,并从供电容量和供电距离两方面分析说明其合理性;针对煤矿负荷对供电系统高可靠性的要求,提出了一种煤矿混合直流供电网络拓扑结构;从供电方式、接线方式、接地方式、运行控制、关键设备、继电保护技术等方面,总结分析了构建煤矿混合直流供电系统涉及的关键技术。最后对煤矿企业建设混合直流供电系统可行性进行了分析和展望。 According to the electrical load characteristics in the coal mine,a sequence of the hybrid DC power system voltage is proposed,and the analysis indicates its rationality from the power supply capacity and power supply distance. A coal mine Hybrid DC power supply network topology is put forward to enhance the reliability of distribution network in coal mine power system. In addition,the key technologies for building hybrid DC power supply system in coal mine are summarized and analyzed,such as distribution modes,connection modes,grounding modes,key equipment,operation control strategies and relay protection technologies. Finally,the feasibility of implementing a hybrid DC power supply system in coal mine is briefly analyzed.
