本论文主要阐述线损和线损率的基本概念及控制线损率的基本方法。在输配电过程中，电能的传输和电磁能量的转换都是通过电流实现的，电流通过导线或电气设备时均会产生损耗，所以线路损耗在电力系统中是普遍存在的。线损的存在不仅会造成电力资源的浪费，同时在一定程度上增大了企业的经济负担，所以线损率也是供电企业一项重要的技术经济指标。降低线损率不仅可以降低输电的能耗，还能提高电力供应能力，加强供电网络的经济运行，增加了供电企业经济效益。

This paper mainly expounds the basic concepts of line loss and line loss rate and the basic methods of controlling line loss rate. In the process of power transmission and distribution, the transmission of electric energy and the conversion of electromagnetic energy are realized through the current. When the current passes through the conductor or electrical equipment, there will be loss. Therefore, the line loss is common in the power system. The existence of line loss will not only cause the waste of power resources, but also increase the economic burden of enterprises to a certain extent, so the line loss rate is also an important technical and economic index of power supply enterprises. Reducing the line loss rate can not only reduce the energy consumption of transmission, but also improve the power supply capacity, strengthen the economic operation of power supply network, and increase the economic benefits of power supply enterprises.<br>
