# 配电网理论线损及其计算方法Theoretical Line Loss of Distribution Network and Its Calculation Methods

Abstract: 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.
