基于STM32的光伏发电自动跟踪系统设计

目前在光伏发电领域,大部分太阳电池板都是固定安装的,为了提高电池板的发电量,设计了一套基于STM32的太阳电池板自动跟踪系统。系统通过步进电机带动双轴机构,实现了电池板对太阳的二维跟踪。本系统以低功耗的STM32为核心处理器,在外围设计了光电跟踪传感器,阴晴检测以及GPS等模块,采用混合跟踪的控制方式提高了跟踪精度。介绍了系统的原理与组成,设计了一套低功耗的间歇跟踪算法。

Design of PV automatic tracking system based on STM32

Currently in the field of photovoltaic power generation,most solar panels were fixedly installed.A set of automatic tracking system of solar panel based on STM32 was designed to improve the power generation of solar panel.The two-dimensional tracking of the solar panel was realized as the system drives the biaxial mechanism through the stepping motor.The low-power STM32 was taken as the core processor,several modules including photoelectric tracking sensor weather detection and GPS were designed in the peripheral,and the tracking accuracy was improved by the hybrid tracking control method.The principle and composition of the system were mainly introduced,and a set of low power intermittent tracking algorithm was designed.
