摘　　要：为了解决采用传统方法进行配电网潮流计算所面临的实际困难,提出了基于流图理论求解线性方程的配电网潮流计算新方法,避免了繁琐的矩阵运算,提高了计算精度,克服了传统算法不适用的配电网特殊环境带来的影响,且该方法不存在计算的收敛性问题及其多解问题,避免了传统的潮流方法的纯“数值计算”所带来的各种误差。In order to solve the problems using traditional methods to calculate distribution network flow, this paper puts forward a new method to calculate distribution network flow based on graph theory. This new method avoids complicated process of matrix calculation, improves the precision of distribution network flow and gets over the problem that traditional methods can not be used in special circumstances of distribution network. The new method doesn＇t have convergence problems and many calculation results. And there is no ealeulational error that exits in traditional flow calculation methods.
