Design And Implementation Of Rural Power Distribution Network GIS System Based On C/S Mode

With the reconstruction process of rural power supply network there is a greater progress in parts of renewed requirements and technological reform. But in the part of the informatization management it is still backward if it compares with the municipal power network. Because of the sustainable development of rural economy the power energy user in the country requires particularly better services and management provided by the power supply enterprises. To speed up the pace of the informatization construction of rural power enterprise is already becoming a topic of general interest. Power distribution network is the supply network of the whole power system and the direct connection part between power system and users, which distributes power energy to the power consumption department, undertakes the most basic and important functions of power grid operating supply chain. Therefore, to enhance the management means of distribution network and the power grid efficiency, and to provide perfect supply service is significantly important to the whole power industry.The paper presents a practical system design of the Rural Power Distribution Network GIS System Based on CIS Mode according to the management status of the Bureau's distribution network in county Fushun by applying GIS technologies and database management techniques and GPS technologies and tools etc. The main contents and results as below:1. The setup of distribution network databaseSpatial database: Spatial data character of distribution network was analyzed in details, and data model of distribution network was set up, and spatial information of distribution network was catalogued reasonably.Distribution network data were acquired by using handhold GPS. The distribution network spatial data of poles, transformers, and switches etc, were coded and inputted into a spatial database. Property database: Property data character of distribution network was analyzed and classified reasonably. The basic data of distribution network in relation to the information of distribution routes and equipments and information property tables and connection layout of substation etc. were inputted into the database. Database integrated: Spatial data and property data were integrated in an entity relationship database management system.2. Mapping of distribution network GISBased on the spatial data acquisition, reasonable layering and coding, the standard distribution network facilities symbol library was constructed and distribution network map was drawn referring related rules and standards of power industry.3. Design and implementation of distribution network GISAn integrated application system based on GIS of the distribution facilities and information management was developed for the distribution network managers. The system has the functions of mapping operation, edition, data management, information inquiry and statistic etc.
