摘　　要：为了提高太阳能的转换效率,普遍采用对太阳进行跟踪以最大限度地获得更多的太阳能。设计了太阳聚焦器和基于光电传感器的太阳跟踪装置,采用日历跟踪与光电跟踪相结合的方式对太阳进行跟踪。设计了一套能够自动使太阳能电池板与太阳光线保持垂直的跟踪系统,实现最大效率地利用太阳能。整个系统结构简单、价格低廉、性能可靠、跟踪精度高。实验表明,该系统的跟踪精度高,跟踪器能够稳定工作,太阳光线垂直照射光斑,达到太阳能热发电所需要的温度,取得了满意的效果。In order to improve solar energy conversion efficiency, we usually used to track the sun to maximize solar gain more. Designed to focus the sun and the sun based on the photoelectric sensor tracking device. It achieves the track of sun by using the combination of both calendar-check track and light-electric track. And achieve the conversion between the two track ways by using a photo electricity diode examination as feedback. A tracking system to assure the solar panels vertical to the solar incident angle to improve the absorbing efficiency is designed. The entire system structure is simple, inexpensive, reliable performance, tracking and high accuracy. After some experiments, we draw the conclusion that the accuracy of this system is high. No matter under any weather,facula vertical sunlight exposure to solar thermal power generation of the required temperature this device can run stably and achieve satisfactory results.
