摘　　要：针对配电网重构中的潮流计算问题,根据配电网的特点,在回路阻抗法的基础上,引入网络层次矩阵,简化了编号过程,并避免了对网络的二叉树转换,保留了网络的原始结构;将多端口原理引入算法,有效地处理了含有PV类型的分布式电源(DG)的网络,最后用算例验证了该方法具有易收敛、易编程、迭代次数少、计算速度快等优点。For the flow calculation of distribution network reconfiguration, according to the characteristics of distribution network, distribution network hierarchical matrix was used in the loop impedance method so as to simplify the process of number, avoid the transformation of network by binary tree and keep the original structure. Multiport network theory was used in the algorithm so as to handle the PV node of distribution network with distributed generation （DG） effectively. At the last,examples showed the advantages of the method like easy convergence, easy programming,less iteration number and fast calculating speed, etc.
