摘　　要：依据配电网潮流计算的回路阻抗法 ,结合配电网结线的特点 ,定义了反映支路电流流向与节点分布规律的关联矩阵 ,提出了形成阻抗矩阵和简单快速的节点、支路的编号方法 ;在此基础上 ,提出了一种配电网潮流计算的新方法。新算法具有编程简单易于实现 ,收敛速度快 。Based on the loop impedance method for load flow algorithm and the characteristics of connection in distribution network, a relevant matrix describing the flow direction of branch current and nodes distribution is established, and a method to form impedance matrix and a simple but fast node and branche numbering scheme are proposed. On the basis of the above, a new method of load flow algorithm for distribution network is presented. The method has the advantages of programming simply, converging fast and computing accurately.
