摘 要: 配电网设备众多、数据繁杂,且需要实时更新各种数据,而传统的数据库更新比较困难。利用CASE工具建立Geodatabase数据库统一建模语言(unified modeling language,UML)模型,并用ArcGIS 9�2部分模块生成Geodatabase数据库,最后以配电网为例完成了地理信息系统(geographic information system,GIS)配电网空间数据库的设计。这样不仅避免了传统数据库建立费时、可移植性差、数据之间映射容易出错的缺点,而且使设计方案更加标准,有利于空间数据库的后期维护。
关 键 词: 电力系统及其自动化;统一建模语言;CASE工具;空间数据库;配电网

Abstract: Because of numerous equipment, multifarious data and requirement of real-time data updating, it is difficult for traditional database to update data. A method that using CASE tool to create UML model of Geodatabase is introduced in this paper, and then Geodatabase based on this UML model is established by a certain module in ArcGIS 9.2. Finally, the design of spatial database of geographic information system (GIS) distribution network is accomplished. This method can not only avoid the disadvantages including time-consuming establishment, weak portability and inaccurate mapping among the data, but also make the design scheme more standard and make the later modification and maintenance more easily.
