针对光伏发电领域的太阳能利用率低,设计了以MSP430 G2553 MCU为控制核的太阳自动跟踪控制系统,其通过提高光伏板的有效受光面积以实现提高太阳能利用率的目的。系统由检测器、控制器和执行机构三部分组成,利用光敏电阻阵列构成的检测器,采集太阳光信号并经过调理电路的处理后,最终送入MCU控制器,通过其处理后产生PWM波,控制执行机构实现对太阳的自动跟踪。试验研究表明,该系统能够提高太阳能电池板的受光面积,并提高了太阳能利用率。
In view of the low utilization of solar energy in the field of photovoltaic power generation, a solar automatic tracking control system designed with MSP430 G2553 MCU as its control core is designed to improve the solar energy utilization efficiency by increasing the effective light receiving area of the photovoltaic panel. The system consists of a detector, a controller and an actuator. The detector consists of a photosensitive resistor array, collects the sunlight signal and processes it in a conditioning circuit, and finally sends it to the MCU controller to generate a PWM wave through its processing. Control the implementing agencies to automatically track the sun. Experimental studies show that the system can improve the light-receiving area of solar panels and improve the utilization of solar energy.
