【摘要】：隨著信息化時代的到來，傳統(tǒng)的電力運營方式已經無法跟上現代化電網建設的腳步，為了保障人們用電安全，迫切需要一種現代化技術手段來管理與規(guī)劃電網的實施。作為信息技術發(fā)展中的熱點之一——三維地理信息系統(tǒng)，對空間數據處理及可視化的有著天然優(yōu)勢，兩種不同領域中的技術應用到一起，會碰撞出怎樣的火花，讓人無限期待�；诖吮菊撐膶⑷S地理信息系統(tǒng)技術應用到電力行業(yè)，來設計與架構電力規(guī)劃方向的三維地理信息系統(tǒng)，實現電網的三維可視化。 本文首先回顧了數字地球技術與電力地理信息系統(tǒng)技術在國內外的研究進展。根據現階段發(fā)展狀況，選取開源的OGRE作為圖形渲染引擎。通過對遙感影像數據、DEM數據進行研究，實現瓦片數據分割，并以OGRE3D渲染引擎為核心，研究如何利用遙感影像數據、DEM數據模擬三維地球表面。然后結合現有的層次細節(jié)模型算法，實現電力設備的三維模型文件在三維場景中加載與渲染。最后綜合以上技術，利用現有數字地球平臺EV_Globe，結合微軟.NET Framework4.0框架、使用C#語言對三維地理信息系統(tǒng)各個功能模塊進行開發(fā)，完成具有三維展示與三維分析等功能的三維數字化電力規(guī)劃系統(tǒng)的實現。 本系統(tǒng)采用合理的計算機技術、三維地理信息系統(tǒng)技術和數據庫技術，能夠真實地、直觀地對三維場景展示，為設計、規(guī)劃、管理等部門提供全方位的觀察視角，可以方便快捷的查詢電網的空間屬性信息、電力模型設備信息等內容，將信息化、系統(tǒng)化融入到數據資源的管理、維護、更新和共享中。這樣不僅可以提高各個部門的工作效率，還可以降低“信息孤島”和管理成本。對于電力行業(yè)的線路規(guī)劃和運營管理有著重要意義。
[Abstract]:With the advent of the information era, the traditional way of electric power operation has been unable to keep up with the pace of the construction of modern power grid, electricity to ensure people's safety, the implementation of the urgent need for a modern technology to management and planning of the power grid. As one of the hot spots of the three-dimensional geographic information system in the development of information technology, the spatial data processing and visualization are a natural advantage, the two kinds of technology in different fields together, will impact what kind of spark, let us infinite expectations. This paper will be the three-dimensional geographic information system technology is applied to electric power industry based on 3D geographic information system to design and construction of electric power planning and direction, to achieve three-dimensional visualization of power grid.
This paper reviews the research progress of digital earth technology and electric power geographic information system technology at home and abroad. According to the present development status, select the open source OGRE as the graphics rendering engine. Through the data of remote sensing image of DEM data, realize tile data segmentation, and OGRE3D rendering engine as the core, to study how to use remote sensing image the data, DEM data simulation of three-dimensional surface of the earth. Then combined with the level of detail of the existing algorithms, 3D model file to achieve power equipment loading in the 3D scene and rendering. Finally the above technology, the use of existing digital earth platform EV_Globe, combined with Microsoft.NET Framework4.0 framework, each function of the three-dimensional geographic information system module is developed using C# language complete the realization, has the function of 3D display and 3D analysis of 3D digital power system planning.
This system adopts reasonable computer technology, three-dimensional geographic information system and database technology, which can truly and intuitively display, the 3D scene for the design, planning, provide a full range of observation from the perspective of management and other departments, spatial information query system can easily and quickly, the power model of equipment information, the information. System integration into data resource management, maintenance, updating and sharing. It can not only improve the efficiency of the various departments, but also can reduce the "information island" and management cost is very important for the power industry line planning and operation management.
