自动跟踪式光伏发电计算机监控系统的设计

Design of automatic tracking photovoltaic generation computer monitoring system

目前太阳能光伏发电的一个主要的问题是发电效率低,这个问题很大程度上制约了光伏发电的应用和发展。提高光伏发电效率的一种重要途径是设计自动跟踪的光伏发电系统,使太阳光线尽可能垂直地入射到太阳能电池板,最大限度地获得太阳辐射能量。从工程应用实际出发,针对多种类型跟踪器的普遍特点,选取双轴跟踪器作为跟踪器类型,基于嵌入式技术设计出一种通用型自动跟踪控制系统。

Solar photovoltaic power generation technologies have gradually become hot issues. However, a bottleneck in the current application of PV power is the low efficiency of power, which largely restricts the PV power generation applications and development. A kind of important way to improve the efficiency of PV power generation was proposed to design automatic tracking system of the PV modules. That is, for receiving maximum limit energy, some control means were used to make the sun light ray perpendicular incident to solar panels as far as possible. From the perspective of engineering application practice and common features of multiple types of tracker, the dual-axis tracker was selected as embedded technology in this thesis.
