The Research On Urban Power Network Computer Aided Planning System Based GIS

Urban Power Network Planning, as a crucial part in power gird developing, it is a complicated system engineering, specially having sweeping scope, excessive uncertain and extensive involved domains. Only depending upon planning-worker'experience, it is unable to satisfied for the requirement of modern power network planning. Leading GIS into the urban power network planning can be easy for gathering and managing the planning data, make the planning work directly visualized and improve the planner's work efficiency. This paper researchs and exploits an urban power network system based GIS for the aim of realizing an integration of GIS and urban power network planning. It can not only relieve labor intensity of planning-workers but also improve scientific decision level of power network planning. It inevitably has important academic and realistic meaning.In this paper, on the base of analyzing the characteristics of urban power network and the process of planning, a GIS platform used for power network planning is constructed based on the MapInfo Professional technology. Using VB and a GIS component called MapX as the developing tool, the problem of connection of power network spatial data and attribute data is resolved, and some detailed interfering rules and program of substation planning is proposed. Substation planning considers that not only increasing capacity or making an extension for exiting substation but also address planning of the new substation. This system edits four kinds of mathematical model in the part of choosing and designing addressing optimization model considering the complicate of the urban power network and the various aims of decision-maker. This system contains rich power network database, planning model-base, planning principle knowledge-base and map graph-base. Some planning function modules are developed. These modules are controlled by system's order, which realizes the manipulation following the planning program in turn. This paper introduces the basic principle and the developing scheme of the urban power network computer-aided planning system. Specially, the substation intelligent planning is the important crucial part of this research. The integration of graph system, database system and planning system is realized by using the Component GIS technology, object-oriented technology and artificial intelligence technology, which makes the planning work visualized and intelligent. Those improve the work efficiency of planning obviously and advance planning level entirely. Finally, the experiment of planning indicates the high efficiency and scientific nature of applying this system to power network planning.
