Research On Support System Of The Power Grid Planning Based On Skyline

Since reform and opening up, China's economy has maintained sustainable and rapid development. China has become the world's electricity production and consumption of power. Along with the power of the increasingly wide range of applications, the power of technology put new demands.Grid planning is the important content in grid construction, Is the necessary means to coordinate urban and rural development planning, directly related to the implementation of urban development planning and the establishment of urban and rural spatial distribution, and now, grid planning meeting the demand of electricity supply, while to meet the requirements of urban and rural development planning , to improve the operability of grid planning ,to make the entire Grid running at maximum efficiency and maximum effectiveness is planner's main research directions.Substation location and power line planning is two major parts of the Grid Plan. Because of the distinct spatial characteristics between these two tasks, resolving the space problem in these tasks is the key to Grid planning.Three-dimensional Geographic Information System (3DGIS) is the best tool to solve the space problem。It is an urgent need for planners to demonstrate the achievement of the Grid planning. To establish the high-precision digital elevation model (DEM) based on three-dimensional space measurement and spatial analysis is also a necessary tool for network planners.In this paper, to solve space problems in network planning is the primary objective. ,. The main characteristics of three-dimensional analysis of geographic information system platform and their respective core strengths and weaknesses were pointed out, Using three-dimensional geographic information system technology to solve critical network planning space technology, and Taking Skyline 3D GIS platform as an example, a network supporting three-dimensional planning system has been designed and implicated.
