光伏聚光发电随动系统研究

为了提高光伏电池转换效率,采用八面光漏斗聚光器将太阳光进行会聚叠加,使相同的光伏组件能够产生更多的电能,从而减少单瓦光伏发电的成本.将带有定时功能的自动跟踪装置与新型太阳能发电聚光器相配合,设计了自动跟踪聚光器的光信号检测装置、跟踪控制电路、驱动电路以及调整装置,通过选用效率高且功耗低的PIC16F916和LMD18245分别作为控制芯片和驱动芯片,极大的提升了系统性能,达到了自动跟踪太阳运行轨迹,提高光伏电池转换效率的目的.

Research on PV Condenser with Tracking System

In order to improve the conversion efficiency of photovohaic cells use optical-funnel-type condenser to concentrate the sunlight is used, so that the same PV modules can produce more electricity, thereby reduce the PV costs of per Watt. The automatic tracking device with timing detecting and the new type PV condenser will be used together in this real-time system. The signal detecting device, tracking control circuit, driving circuit and adjustment institutions of the system are designed. And is chosen PIC16F916 and LMD18245 which have high efficiency and low consumption as the control and driver chips to greatly enhance the performance of the tracking system, and achieve the purpose of tracking the sun automatically and improve the efficiency of PV cells.
