Theoretical Line Loss of Distribution Network and Its Calculation Methods

Abstract

配电网线损理论计算的研究是加强线损管理、节能降损重要技术手段。本文从配电网线损及线损率的定义、构成分类入手，对配电网线损产生原因、影响因素进行探讨；研究了配电网元件的数学模型，总结了配电网线损理论计算方法并进行比较和展望；以海南电网公司文昌地区典型线路为例进行了比较和分析。To study the theoretical calculation of distribution network line loss is an important technical method to enhance the management of line loss and the energy reduction. This paper started by analyzing the distribution network line loss and the definition and constituent of the line loss rate, then discussed the cause of the line loss and the influencing factors. The mathematical model of distribution network elements was studied, and the methods of calculating the line loss were con-cluded and compared. At last, the typical lines of Wenchang in Hainan Power Grid were taken for an example to be compared and analyzed.
