摘　　要：介绍了一种以PLC为控制器的聚光极轴式太阳能自动跟踪系统。系统使用极轴式跟踪思想,利用合理的天文算法和对太阳的运动轨迹分析,将复杂的二维自动对日跟踪简化为一维极轴旋转式跟踪,在保证了系统对日跟踪精度的同时,极大地降低了系统的投入成本和自身能耗,增加了系统的可靠性,因此大幅提高了太阳能发电系统的总经济效益。This paper presents a focusing polar axis sun tracking system under control of PLC.With the thought of polar axis tracking,the system combines the excellences of both reasonable astronomical algorithms and analysis of the trajectory of the sun,so that it makes complex two-dimensional auto sun tracking system simplified into one-dimensional rotating polar axis sun tracking system. It not only reduce the cost,but also increase the reliability of system,meanwhile,it ensures the accuracy of sun tracking.So this sun tracking system can increase the economic benefits of solar power generation system.
