中文摘要：
利用地理信息系统（GIS）对电力网络进行存储和分析是电力行业信息化发展的一个重要内容．电力GIS网络除了具有普通GIS中的空间位置和拓扑结构数据外．迁需要描述网络的逻辑结构，为了便于存储和分析这种特有的逻辑结构数据并满足统一数据管理和分布式系统开发的需求．在传统GIS软件和开发组件普遍使用的“空间数据＋属性数据”模式的基础上．定义了一组基于关系数据模型的适应电网运行规则的层次化表结构：基于实际电力网络的建模和分析表明．该模型比较是话完整地表示了从宏观电力两络层到局部厂站中一次设备接线网络层的各种数据关系．便于进行快速的网络连通性分析和网络结构的编辑修改操作。
英文摘要：
It is very important for the development of information technology in the power industry to store and analyze the power networks using the Geography Information System （GIS）. The ordinary space and topology data is necessary to the power networks in GIS, the data for describing the logical structure of the networks is also necessary. In order to store and analyze the logical structure data and meet the need of uniform management of data and development of distributed information system, a set of hierarchical tables based on the relation data model was designed to match the characteristic of the power networks by improving the traditional space ＋ attribution data management mode in GIS. It has been shown that the tables can represent the logical structure data of the macro power networks and the local electric networks and are convenient to the connectivity analysis and flexible modification of networks.
