摘要
针对配电网重构时网络潮流方向发生变化,提出了一种基于"短接"操作的配电网拓扑分析算法。该方法可对节点和支路进行任意编号,不需要对网络进行广度优先搜索或深度优先搜索,对末稍节点进行简单的"短接"操作便可得到网络拓扑矩阵。在潮流计算时利用网络拓扑矩阵构造运算矩阵,简单的处理代数方程就可以计算支路电流、节点电压和功率分布,使得程序实现起来更加高效、准确。根据提出的算法,编制了应用于配电网络重构的潮流算法程序,用IEEE33节点算例验证了该算法的可行性。
Considering changing of power flow directions when the distribution network is reconstructed,this paper proposes an algorithm of topological analysis for distribution net-works based on the short operation.This method can number any node and branches arbitrarily without the first search of the network's width or depth and can get the network's topological matrix by simply short operation with tip nodes.The mathematical operation matrix is constructed by using network's topological matrix in the process of power flow calculation,and by simply dealing with algebra equations the branch current,node voltage and power distribution can be calculated,thus the program is made more efficient and accurate.A program of distribution network power flow is developed according to the proposed algorithm,and feasibility of the proposed algorithm and pro-gram are verified by the case of IEEE33.
