Design of Dish Solar Automatic Tracking System Based on PLC

太阳能是一种可再生清洁能源,它的开采和利用能够有效解决能源危机和环境污染问题,如何最大限度提高太阳能利用率仍是当今国内外研究热点。本文提出了一种以PLC为控制核心,采用视日运动轨迹跟踪和光电跟踪相结合的混合式跟踪模式,实现全天候高精度跟踪太阳光,提高了系统的跟踪精度。实验结果表明,该系统具有良好的跟踪效果,与天文算法计算出的理论值偏差0.1度,最大程度上提高了碟式太阳能发电装置的发电效率,具有广泛应用前景。

Solar energy is a renewable and clean energy.Its exploitation and utilization can effectively solve the problem of energy crisis and environmental pollution.At present,how to maximize the utilization of solar energy is still a research hotspot at home and abroad.This paper presents a hybrid tracking mode with PLC as the control core and the combination of apparent solar trajectory tracking and photoelectric tracking,which realizes all-weather high-precision tracking of sunlight and improves the tracking accuracy of the system.The experimental results show that the system has good tracking effect,and the deviation from the theoretical value calculated by the astronomical algorithm is 0.1 degrees,which improves the power generation efficiency of the dish solar power generation device to the greatest extent,and has a wide application prospect.
