摘要
本文介绍了太阳跟踪系统的控制原理、控制算法和系统硬件组成,并重点介绍了控制电路的结构和原理,给出了软件的设计思路及主要的程序流程图。同时,在考虑当地的气象基础上设计一种跟踪精度高、结构简单、控制可靠的太阳能跟踪系统。实验结果表明,在太阳辐射强度、环境温度变化时,系统仍能准确地跟踪到太阳能电池的最大功率点,从而有效提高了太阳能电池的光电转化效率,具有广泛的应用前景。
This paper descriked the solar tracking system control theory, control algorithms and the system hardware components, introduced with emphasis on the structure and principle of the control circuit, and gave the software＇ s design mentality and the main program flow diagram. The paper also designed a high precision, simple structure, reliable control of solar tracking system on the basis of considering the local weather. The experiment result shows that as the solar radiation intensity and ambient temperature change, the system can still accurately track the solar cell maximum power point to improve the photoelectric effieieney, and has the widespread application.
