As the continuous development of the power grid, and the rapid growth of the electrical load, it brings the whole modern electric power enterprise management field an important topic: decreasing the line loss and energy conservation. The line loss rate is a comprehensive technical and economic index for a electric power enterprise, which reflects efficient energy use and power supply enterprise management level. This paper introduces several different installation positions of distribution transformer, through the analysis and calculation, to determine the effect of low pressure loss. According to the load moment balance principle, this paper finds a optimal location of distribution transformer by calculations, which play the role of the line loss decreasing d energy conservation.%随着电网的不断发展与用电负荷的快速增长,搞好降损节电工作已成为现代电力企业管理的一项重要课题.线损率是供电企业一项综合性的技术经济指标,反映能源的有效利用及供电企业的经营管理水平.本文通过配电变压器几种不同安装位置,分析并计算其对低压线损的影响,最后用负荷矩平衡原理计算出配电变压器的最佳安装位置,从而做到降低线损,节能减排的作用.
