在煤矿企业高压输供电过程中,电能传送和电磁能量转换都是通过电流实现的,电流通过导线或电气设备时会产生损耗。线损是电能在传输过程中所产生的有功、无功电能和电压损失的简称,线损管理是供电线路的一项重要工作,线损率是电力系统规划设计、生产运行、经营管理和企业经济效益水平的综合体现。文章通过对煤炭企业供电网络负荷进行分析整理,针对影响煤矿110kV供电网线损的多种因素,对煤炭企业高压供电网络的理论线损进行了分析与计算,并对煤矿企业110kV供电网的降损措施进行探讨。
In the process of high-voltage transmission and power supply in coal mines, both the transmission of electric energy and the conversion of electromagnetic energy are realized by means of current, and the loss of electric current when passing through the wires or the electric equipment occurs. Line loss is the abbreviation of active and reactive energy and voltage loss generated during the transmission of electric energy. Line loss management is an important work of power supply line. The line loss rate is the power system planning and design, production and operation, operation and management, and enterprise A comprehensive reflection of the level of economic benefits. In this paper, through analyzing and sorting the load of power supply network in coal enterprises, the theoretical line loss of high voltage power supply network in coal enterprises is analyzed and calculated according to many factors that affect the line loss of 110kV power supply network in coal mines. Measures to explore.
