10MW塔式电站定日镜场的设计(论文14500字)
摘 要
太阳能塔式热发电站主要构成系统部分是定日镜场、它家、吸热储热配套装置及发电配套装置构成。整个装置工作原理大致为定日镜将太阳能汇集到吸热器，利用传热储热装置将能量传递到发电机处，将能量以电能的方式输出。其中最为关键的部分是定日镜部分，它的组成部分成本基本占整个电站的四成以上。它由跟踪太阳运转的定日镜及相应控制系统组成。镜场优化设计是通过设计定日镜的面形和镜场布置，获得最优的聚光性能，同时尽量降低成本。
本文的设计主要是从定日镜的跟踪技术和定日镜场的布置方式以及定日镜、定日镜场、塔高和吸热器之间的关系展开分析，同时介绍两种软件MATLAB和HFLD，并利用软件对镜场的一些几何问题以及其跟踪技术和镜场的性能进一步进行分析从而达到对定日镜场进行优化并更深层次的处理镜场效率常见的几大问题。最后对软件进行验证 PS10 公布的数据和HFLD 软件的计算结果进行对比，证明了 HFLD 软件在计算方面的准确性。

Abstract
Solar tower thermal power plant, also known as the central heating system is mainly composed of heliostat field, tower, central heat absorber, heat transfer of thermal storage devices and thermal power generation device, use the heliostat tracking the sun and the solar energy into heat receiver is located in the top of the tower, and then by the heat transfer/heat exchange device to transmit heat to heat generators, finally obtain the power output. The helioscope field is a key component of solar tower thermal power generation system, accounting for over 40% of the cost of the power station. The optimum design of the mirror field is to obtain the best concentrated light performance and minimize the cost by designing the surface shape and the layout of the sun setting mirror.
In this paper, the design of the main from of heliostat tracking technology and the way of heliostat field layout and heliostat, heliostat field, high tower, and analyzes the relationship between the heat absorber, at the same time introduce two kinds of software MATLAB and HFLD, and use the software to lens field of some geometric problems, and its tracking technology and mirror field analysis so as to achieve the performance further optimize the heliostat field and deeper processing mirror field efficiency of several major problems. Finally, the software is verified by comparing the data published by PS10 with the calculation results of HFLD software, which proves the accuracy of HFLD software in calculation.
