摘要
在塔式太阳能热发电中,应用全新的跟踪聚光理论——陈氏跟踪方法[1],以PIC16F877单片机为控制核心,设计了闭环控制的定日镜跟踪系统。与传统的跟踪方式相比,自旋+仰角跟踪方式使得定日镜的像差小,可实现在任何气候条件下对日的稳定可靠跟踪。
A heliostat tracking system controlled by closed loop has been designed, which takes singlechip computer PIC 16F 877 as the control core and uses the Chen＇s theory- an innovative theory of tracking and focusing in solar energy thermal power generation. Comparaed with traditional tracking mode,the said new tracking mode makes small aberration of the heliostat,and a stable and reliable tracking for the sun in any climatic condition can be realized.
