摘　　要：太阳能是当前具有代表性的绿色能源之一,固定式光伏支架由于安装方向固定,光伏面板无法始终朝向太阳,而光伏逐日系统的监控系统对于跟踪其性能和确保高效运行至关重要。因此,该文提出一种基于监控系统中可适用于弱光条件下的光伏逐日系统,采用信捷XC3 PLC承担其主要程序控制任务,利用光敏传感器收集各个方向的光强差值,通过程序计算出最佳光照角度,进而驱动电机调整为最佳照射角度,将云量和天气预报数据集成到监测系统中,以预测阳光变化并相应地辅助逐日系统运行。大幅提高光电转化率。Solar energy is currently one of the representative green energy sources.Due to the fixed installation direction of fixed photovoltaic brackets,the photovoltaic panels cannot always face the sun.The monitoring system of the photovoltaic Sun Tracking System is crucial to tracking its performance and ensuring efficient operation.Therefore,this paper proposes a photovoltaic Sun Tracking System based on the monitoring system that can be suitable for weak light conditions.Xinjie XC3 PLC is used to undertake its main program control tasks.Photosensitive sensors are used to collect light intensity differences in various directions,and the program calculates the optimal illumination angle,and then drives the motor to adjust to the optimal illumination angle,integrating cloud cover and weather forecast data into the monitoring system to predict sunshine changes and assist the Sun Tracking System accordingly and significantly improving the photoelectric conversion rate.
