光跟踪控制器应用技术探析

Analysis of Application Technology of Optical Tracking Controller

光伏双轴跟踪系统的核心是算法,算法依托光跟踪控制器而存在,因此光跟踪控制器的重要性不言而喻。当阳光照射到感光传感器的时候,感光传感器会将采集的光照强度通过工业总线接口动态传输到控制器。根据不同季节的天气情况构建太阳光运动轨迹模型,在基于太阳光运动轨迹模型前提下,感光传感器传递过来的数据通过物理跟踪驱动算法处理后会产生相应的反馈驱动标志位,控制器会根据反馈驱动标志位直接驱动电机使光伏板垂直于阳光,完成一次调整周期。如此不断调整,时刻沿着太阳的运行轨迹追随太阳,构成一个闭路反馈系统,实现阳光的自动跟踪,让光伏发电效率持续最大化。

There is no doubt that the core of photovoltaic dual-axis tracking system is the algorithm,the algorithm relies on the optical tracking controller exists,so the importance of optical tracking controller is self-evident.When the sunlight hits the sensor,the sensor will dynamically transmit the collected light intensity to the controller through the industrial bus interface.According to the different seasonal weather conditions to build the sun trajectory model,under the precondition of trajectory model based on the sun's rays,photosensitive sensor passed by physical tracking algorithm for data processing after will produce corresponding feedback driver symbol,the controller will sign a direct drive motor according to the feedback to make photovoltaic panels is perpendicular to the sunlight,to complete a cycle adjustment.Such constant adjustment,always follow the sun along the running track of the sun,constitute a closed-circuit feedback system,realize the automatic tracking of sunlight,so as to maximize the efficiency of photovoltaic power generation.
