摘　　要：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,既可以将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,提高搜索效率.基于Geodatabase模型,利用UML建模语言和ArcGIS提供的Case工具,设计并实现具有拓扑关系的配电GIS数据库.这种数据模型和设计方法比传统方法更直观、简单且易于修改,对配电网的描述更贴切,利于数据库设计修改与优化.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 designs and realizes the database for distribution network successfully using the modeling language UML and Case tools which is provided by ArcGIS.In view of the characteristics of distribution network data structure,and based on the Geodatabase model,it provides a feasible method in distribution network database designing.This data model and designing method intuitional,simple and easy to modify compared with traditional methods.This method is a better one to design spatial database because the description for distribution network is more appropriate.
