【摘要】：太陽能是一種可再生的清潔能源,如何應用太陽能解決能源和污染問題是當前的重要研究方向。塔式太陽能熱發(fā)電技術作為理想的大規(guī)模發(fā)電方式,其應用前景十分廣闊。其中聚光鏡場設計是電站設計的核心,但是目前可查的聚光鏡場設計方法中存在不完善的問題。同時,三維視景仿真技術日益成熟,其應用從最開始的軍工領域推廣到工業(yè)設計、醫(yī)療、教學等眾多領域中,并推動對應領域的發(fā)展。本論文對塔式太陽能熱發(fā)電站聚光鏡場設計方法與定日鏡聚光追日過程進行研究分析,并且結合三維視景仿真技術的優(yōu)勢和特點,應用Pro/E、MultiGen Creator、Vega Prime及Visual Studio軟件建立基于MFC的可視化聚光鏡場視景仿真系統(tǒng)。本論文的主要成果有以下幾點：1.通過調(diào)研國內(nèi)外文獻,提出了以放射狀柵格法為理論基礎的輻射網(wǎng)格狀聚光鏡場排布方式,在此基礎上建立定日鏡位置坐標的數(shù)學模型,形成了較為完善的聚光鏡場設計方法。該布置方法較為有效的避免較大的光學損失。2.通過對太陽運行軌跡的分析,建立了以太陽高度角和方位角為指標的太陽運動模型并驗證該運行算法的有效性。進一步分析定日鏡的運行方式和對太陽光的反射原理,在太陽運動模型的基礎上,建立以定日鏡高度角和方位角為指標的定日鏡追日模型。3.以額定功率為70KW發(fā)電站為仿真對象,通過Pro/E建立仿真模型,采用Creator/Vega Prime完成仿真系統(tǒng)的模型簡化、配置和驅(qū)動,實現(xiàn)可視化視景仿真效果。4.以Visual Studio為開發(fā)平臺,通過Vega Prime和OpenGL混合編程,開發(fā)出了可以重現(xiàn)聚光鏡場追日過程的視景仿真系統(tǒng)。交互界面中設置有豐富的菜單功能,對應有快捷鍵操作方式,并添加仿真場景實時信息顯示窗口實時顯示仿真場景運行參數(shù)。該視景仿真系統(tǒng)功能較為完善、具有友好的交互界面且操作簡單,達到了較為理想的效果。在實際使用中,系統(tǒng)既可用于聚光鏡場設計中,幫助用戶快速直觀獲得太陽和定日鏡相關參數(shù)信息,也可用于教學或演示中,幫助觀察者直觀的理解塔式太陽能熱發(fā)電站工作原理與聚光鏡場追日過程。
[Abstract]:Solar energy is a kind of renewable clean energy. How to apply solar energy to solve the problem of energy and pollution is an important research direction at present. As an ideal large-scale power generation method, tower solar thermal power generation technology has a broad application prospect. The design of focusing mirror field is the core of power station design, but there are some imperfections in the design method of focusing mirror field. At the same time, 3D visual simulation technology is becoming more and more mature, and its application is extended from the initial field of military industry to many fields such as industrial design, medical treatment, teaching and so on, and promotes the development of corresponding fields. In this paper, the design method of focusing mirror field and the focusing process of solar mirror in tower solar thermal power station are studied and analyzed, and combined with the advantages and characteristics of 3D visual simulation technology, Pro/E,MultiGen Creator, is applied. The visual scene simulation system of visual concentrator based on MFC is established by Vega Prime and Visual Studio software. The main results of this paper are as follows: 1. Based on the investigation of domestic and foreign literatures, the field arrangement method of radiative grid focusing mirror based on radiative grid method is put forward. On this basis, the mathematical model of the position coordinate of helioscope is established, and a perfect design method of concentrator field is formed. This arrangement method is more effective to avoid large optical loss. 2. Based on the analysis of the solar trajectory, a solar motion model with the solar altitude angle and azimuth as the index is established and the effectiveness of the algorithm is verified. The operation mode of the helioscope and the reflection principle of solar light are further analyzed. On the basis of the solar motion model, a solar tracking model is established, which takes the height angle and azimuth angle of the fixed helioscope as the index. Taking the rated power as the 70KW power station as the simulation object, the simulation model is established by Pro/E, and the model simplification, configuration and drive of the simulation system are completed by Creator/Vega Prime, and the visual scene simulation effect is realized. 4. Taking Visual Studio as the development platform, through the mixed programming of Vega Prime and OpenGL, a visual simulation system is developed, which can reproduce the daily pursuit process of the focusing mirror field. There are rich menu functions in the interactive interface, the shortcut key operation mode should be set, and the simulation scene real-time information display window is added to display the simulation scene running parameters in real-time. The visual simulation system has perfect function, friendly interactive interface and simple operation, and has achieved ideal results. In practical use, the system can not only be used in focused mirror field design, to help users quickly and intuitively obtain the sun and helioscope-related parameter information, but also can be used in teaching or demonstration. To help observers intuitively understand the working principle of tower solar thermal power station and the sunpursuit process of focusing mirror field.
