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.
