Automatic One-dimensional Polar Axis Sun Tracking System Based on Controlling PLC |
| |
| Abstract: | 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. |
