基于几何网络的配电网拓扑分析方法及其应用

Topology analysis of distribution network based on geometric network and application for listing simulation operation

配电网拓扑结构复杂,配电设备变更频繁,不易描述,利用Geodatabase数据模型中的几何网络对配电拓扑结构进行描述,可以将GIS与配电网拓扑统一起来,又可以充分利用几何网络强大的拓扑分析功能,提高搜索的效率。文中提出了一种基于几何网络的配电网拓扑分析新方法,详细阐述了怎样基于几何网络来描述配电网,结合南阳配电GIS项目给出了在网络分析的挂牌操作功能中成功应用这种新方法,并给出了具体的实现算法和流程。

The topology of distribution network is not easily described because of its complex structure and frequent changes in equipment. Geometric network in Geodatabase data model describes distribution topology exactly, which not only unifies the topology of GIS and distribution but also takes full advantage of the powerful geometric topology network analysis functions to improve search efficiency. This paper proposes a new distribution analysis method based on geometric topology. The method details how to describe the distribution network based on geometric network. With the project of Nanyang distribution network GIS, the new method is applied successfully in the listing simulation operation function. In the end part, the paper gives the implement arithmetic and flow chart concretely.
