摘要
当今世界能源短缺,环境污染,化石能源濒临枯竭,在这种情况下,可再生能
源的利用就显得尤为重要。太阳能以其储量的无限性、存在的普遍性、开发利用的
清洁性以及逐渐显露出的经济性等优势,其开发利用是最终解决常规能源特别是化
石能源带来的能源短缺、环境污染和温室效应等问题的有效途径,是人类理想的替
代能源。
本文在分析总结太阳能利用方式和的基础上,运用相关
的理论,提出和设计了一种发电功率为 500W,旋转抛物面集热器直径为 1m,釆用
方位角—高度角双轴精确跟踪太阳的碟式斯特林太阳能发电系统。该系统功率比较
小,结构相对简单,效率较高,成本低。非常适合我国大面积的偏远山区、草原、
沙漠,或电网未覆盖的地区等以户为单位的日常照明等生活用电,对改善偏远地区
人民的生活水平有积极作用。
本文除完成小型斯特林太阳能发电系统的结构设计外,还研究和设计了太阳双
轴跟踪系统。提出了视日运动轨迹跟踪(程序控制)和传感器跟踪两级混合跟踪方案,
并运用 VC 语言开发了跟踪软件,完成了太阳运行轨迹校核计算和模拟。从而实现
了全天候和高精度跟踪太阳,达到了提升集热温度,提高太阳能的利用率和系统的
发电效率之目的。

Abstract
About energy consumption, there is same problem, such as Energy shortage,
Environmental pollution, and the fossil sources dring up. In this case, it is very important to
develop and utilize renewable energy. Solar energy have some advantages, for example
limitless reserves, distributing everywhere, cleanness and economical. So it is the way to
solve Energy shortage, Environmental pollution, and greenhouse effect to develop and
utilize renewable energy, and is human perfect replaceable sources.
Solar energy utilization means and status are introduced, on this base, the dish-stirling
solar power generation system is proposed. The system’s electric power is 500W, the solar
concentrator’s diameter is 1meter, uses elevation-azimuth tow-axes sun-track equipment.
This system’s characteristic is low power, simple configuration, high efficiency, low cost. It
is very suitable to some places, where is out of the way area, plain, desert and some place
without electricity. The low power system would use to light and daily electricity for a door.
It could improve this place people standard of living.
In the paper, some part is about the tow-axes sun-track equipment. Tow mix
sun track system is presented. Which includes program control and sensor track. The track
control software which is develop wit
