| 摘 要： | 为了提高光伏发电的效率,设计了双轴太阳能跟踪装置。本设计以ATmage16单片机作为控制芯片,在选用高精度太阳位置算法的基础上,用光敏电阻对视日跟踪进行角度微调。并且通过分析装置运行时的耗能和产能的关系,对不同时间段的跟踪次数和跟踪间隔进行优化。理论分析与实验结果表明,该方案能够准确跟踪太阳,且能有效提高太阳能的利用率。

| Abstract: | In order to improve the efficiency of photovoltaic power generation,the biaxial solar tracking device was designed with ATmage16 microcontroller as the control chip,on the basis of choosing high accuracy sun location algorithm,by using photosensitive resistance eye tracking Angle fine-tuning.And the tracking number and tracking intervals at different time were optimized through the analysis of relationship between energy consumption and production capacity during the device runtime.Theoretical analysis and experimental results show that the scheme can accurately track the sun,and can effectively improve the utilization rate of solar energy. |
