摘要:
      本系列前两文已分别阐述了变电站为中心配电网SCDN单线图的图数模型和第一阶段的接线图初始布局算法;本论文将重点阐述第二阶段,即基于初始布局的SCDN单线图美化优化计算。基于前文提供的SCDN初始单线图布局中不存在难以消除的交叉,而力导算法迭代时,部分节点会跨越其一级节点而在本馈线内存在交叉,所以设计了本馈线的二级及以下级别的“节点群” “惯性力(inertia force)”,使得其具备一定的惯性而不被其他外加力而导致节点群分裂分离;以交叉点为目标函数,提出了基于遗传算法的考虑引力、考虑点边-边边规避的总斥力、重力、惯性力的各参数优化计算方法;经过5个实际110kV变电站的10kV配电网SCDN进行了验证,本方法可以生成接线高识别的单线图。
Abstract:
      The previous two papers in this series have proposed a data-diagram model and an initial layout auto-generation algorithm for single-line diagram of substation centralized distribution network (SCDN), and this followed paper will focus on beautifying and optimization for the initial layout single-line diagram. The line intersection number of the initial layout single-line diagram has been greatly minimized even to zero, however, the iterative calculation of force-directed algorithm will yield many line intersections caused by the lower class line branches over cross the upper class line sections, therefore, a new force called “inertia force” on the lower class “node cluster” to keep their nodes as a cluster having a certain inertia force to avoid their nodes separating and splitting caused by outside forces. An optimal parameter setting for force-directed approach is provided to minimize the line intersections through optimizing the parameters of different forces consisting of attraction, impulsion between node to node, node to edge and edge to edge, and gravity force, inertia force, etc. Generic algorithm (GA) is used to solve this optimization problem. 5 real 110 kV substations 10kV networks are testified which give a very satisfied single-line diagram with a high identification of connection (HIC) performance.
