摘要
煤矿供电系统是煤矿生产中的重要系统,其稳定运行是煤矿正常生产的基础,以某煤矿35 kV变电站作为研究对象,从电力系统谐波和继电保护两方面分析提高煤矿供电系统可靠性的设计方案。
Coal mine power supply system is an important system in coal mine production. It is the basis of normal coal mine production during stable operation. This paper takes a 35 kV substation in coal mine as the research object. From the two aspects of power system harmonics and relay protection,the design scheme for improving the reliability of coal mine power supply system is analyzed.
