Development Of Power Distribution Net Geograghy Information Managemen System

With the growing scale of the interconnected power system, power system towardthe direction of automation and highly information-oriented development, modernpower companies need to manage large power equipment data, the geographicinformation system is an important part of the distribution automation system, it is theuse of database technology in the electricity distribution network equipment spacepositioning data and attribute data correspond to the comprehensive analysis andretrieval of spatial location data, build a spatial database system topology and analysiscapabilities, production information and graphical information to reflect geographicalcombination of information management systems.By use of VC++software and the map control on MapX, based on geographicinformation technology and SQL Server2000database management tools, a distributionnetwork management system was developed.The following are the main jobs of this paper.1. Distribution network database design, implementation of a single entity all kindsof information integration and information integration of the entire distribution network,and converted into a graphical database of the geographic information system, thecorresponding properties of the components of the attribute database. The geographicinformation system contains a large number of graphics data that reflect the geographicinformation are very different due to the organizational structure of the organizationalstructure of the graphical data and purely data in database design for graphical data andnon-graphical data of different treatments, they were placed in different types ofdatabases to be managed.2. Development of a detailed study of GIS technology, combined with the VC++programming software in the MFC class library and can be embedded provided by themap control MapX powerful functionality developed based on geographic informationtechnologies with grid management system, this management system contains threemain function: a system security module, data management module and map module.3. Upon completion of the actual operation and testing and modification based distribution management system developed on the basis of geographic informationtechnologies, the function of each module of the system, the practicality of theDistribution Management System developed by the testing and validation, furtherimprovements and extension work has laid a good foundation.
