太阳能电池板追日自动跟踪方案的研究

摘要

The scheme of adopting different trace model under different weather conditions was designed in this paper.First,the detection method of the light intensity and the direction of the sun was presented ,and the weather conditions can be determined by the light intensity and the intensity of the solar radiation . Second,the variation of height and azimuth of the sun in the orbit of the sun were studied ,and then the angle that the solar cell plate need to rotate can be obtained .Last,the advantages and disadvantages of the photoelectric tracking and the tracking of solar orbit were analyzed ,and then both of them were combined to realize the stable and reliable tracking control of solar panels in any climate .%设计了在不同天气情况下采取不同跟踪模式的方案. 首先,提出了光强和太阳方位的检测思路,并通过光照强度和太阳辐射强度波动大小来判定天气状况;其次,研究了太阳运行轨迹中高度角和方位角的变化规律,得到了太阳能电池板需要转动的角度;最后分析了光电跟踪和太阳运行轨迹跟踪的优缺点,并将两者进行有机结合,实现了太阳能电池板在任何气候下都能稳定而可靠地跟踪控制.
