基于配电GIS动态拓扑关系生成电气接线图

GIS-based dynamic relationship of topology to generate electrical diagrams of distribution network

为了生成配电网馈线的电气接线图,以ArcInfo的几何网络为研究对象,提出了基于树的配电网模型。模型以网络动态拓扑关系为出发点,对各个用电设备按供电线路分类,依据距离电源点的远近进行分层处理。画电气接线图时,按层次排放和元素数量均衡排列。为了防止连线交叉,对个设备元素进行排序,使子节点绘制编码与父节点的大小顺序一致。算例结果证明了所提出的方法在多电源的情况下仍切实可行。

In order to generate electrical diagrams, a tree-based model for distribution network is proposed by studying the Arclnfo network. In the model the relationship of dynamic network topology is treated as starting point, and then all electrical equipments are classified according to their feeder lines and multi-layered by the distance from its power source. On the electrical diagram, all electrical elements are arranged evenly by their layer-value and elements＇ number of per layer. At the same time, equipment elements are sorted to keep the consistency of child points＇ ordered-code with their father points＇, which will remedy the occurrence of intersection. Finally, example result indicates the feasibility of the proposed method in the case of multi power source.
