The development and application of GIS on power marketing and expansion

The paper was finished the development and design of the big customer of power expansion system on the basis of mapinfo platform and combining GIS system technology according to the practical problem appeared in area power company traditional marketing and expansion operating mode. The system that power attribute information and geographical graphic information were combined organically was mainly achieved the functions of image layer, zooming graphic, statistical analysis and the localization and fuzzy search of power facilities such as power substation, switching station, and also the application function of GIS system links to the CAD system and SCADA system. Practice shows that: The application of GIS system on power marketing and expansion system, can not only realize the effect of visual display, quick inquiry, and data management and update of power facilities and circuits, but also be connected with other system data, and exist data graphically. The most important function of system is improving the working efficiency, avoiding the repeated investment, and saving lots of resources and operating costs.
