摘　　要：配电网为树状结构,这与数据结构理论中的“树”结构非常相似。配电网潮流计算程序多以二叉树结构实现电网电气元件的数据结构建模,用二叉树遍历技术辨识前推回代中的节点层次关系。提出一种以关联矩阵自乘取代二叉树结构建模的配电网潮流前推回代改进算法,可对支路分层并行计算,无需对线路和节点的繁杂编号,不用复杂的数据结构分析,编程简便易行。用VC++6.0编制应用程序,对IEEE33节点树状网的潮流计算表明了方法的有效性。The tree structure of distribution network is similar to the 'tree' in data structure theory.The 'binary tree' is usually used in distribution network flow calculation for data structure modeling of electrical element,and the traversal technique is used to identify the layer relation of nodes in back /forward sweeping algorthm.An improved back /forward sweeping algorithm using incidence matrix squaring instead of 'binary tree' structure modeling is presented for distribution network flow calculation,which calculates the layered branches in parallel,and needs neither miscellaneous numbering of lines and nodes nor complicated data structure.By developing the application program with VC++ 6.0,the flow calculation in an IEEE 33-node tree network shows its effective.
