摘　　要：提出了一种新的基于前推回代的配电网络潮流算法,该算法能较好地处理弱环网接线方式。考虑了两种不同类型的环网接线方式,并且易于多馈线网络。采用戴维南敏感阻抗矩阵分析法把环网处理和PU节点的处理统一起来,简化了分析过程,使得该算法的计算效率大大提高。理论分析和实例证明该算法快速有效,符合配电网络的分析实际需要。A modified power flow algorithm of distribution network based on forward/backward sweep method is presented,which can deal with the weakly meshed network well.It takes two kinds of loop network connection modes into account,suitable to multi-loop networks.This algorithm unifies loop network treatment and PU bus treatment with Thevenin sensitivity impendence matrix,which simplifies the analysis process and improves greatly the algorithm efficiency.Theoretical analysis and calculative example show that the algorithm is fast,effective and in accord with the practical de-mands of distribution network analysis.
