三维配电网地理信息系统的研究与实现

提高电力企业信息化管理水平是配电网管理中的一项重要内容，目前二维配电网GIS系统已经成为主要的管理手段。针对配电网特点和二维配电网GIS系统中几何图形简单，无法真实反映配网设备及周围环境情况的不足，进行了三维GIS研究，提出了建立三维配电网GIS系统的实施方案。系统采用SuperMap组件式GIS平台，商用关系型数据库SQL2005和VB进行开发，实现了对配电线路和供用电设备等的可视化管理，并具有进行基本的空间分析和数据处理 功能。

Research and design of a three-dimensional GIS-based distribution network management system

To improve the power enterprise information management level is an important part of management for distribution network, with the two-dimensional distribution network GIS system as the major tool at present. According to the characteristics of distribution network and the shortcomings of two-dimensional distribution network GIS system for simple geometry and not being a true reflection of the distribution network equipment as well as its surrounding environmental conditions, this paper carried out the study of three-dimensional GIS and provided an implementation plan of establishing a three-dimensional distribution network GIS system. The three-dimensional distribution network GIS system was developed based on component GIS platform-SuperMap, the commercial relational database-SQL2005 and VB, which realized the visual management of power distribution lines and equipments, basic spatial analysis and data processing.
