光伏组件的最佳倾角跟踪系统设计 摘 要 能源，也就是能量资源。为人类生产生活提供能量，来给人们的生产生活带来帮助。随着人们生活水平的提高，人们对各种能源的需要也越来越高。能源对社会的发展和进步也起着重要的作用。石油、煤炭、天然气是当今社会发展的三大主流能源。随着人口的增加和社会的发展，能源正在被不断消耗，能源问题已经成为人类需要解决的重要问题之一。因此开发新能源已经刻不容缓。越来越多研究正在把目光投向能量巨大的太阳能，并在对太阳能的利用率上不断进行研究，以求扩大太阳能的应用范围。虽然我国研究人员正在不断研究开发但相对于国外来说仍然有一定的差距，并且在太阳能的开发以及应用的范围等方面还相对不够广阔。本篇文章主要是对太阳能进行研究发现，介绍了太阳能在人类生活中有着良好的应用前景。为了能够增强对太阳能的使用率，本文通过制造了一个跟踪系统来实现目的，其中光伏组件可以自动跟踪太阳的方向就是主要的原理。本设计过程分为四步，分别为设计的原理、编程、PCB图和试验分析。本论文也重点介绍了整个系统的设计原理和思路。本设计使用了四个光敏电阻对太阳光线的照射强度进行感应，在不同光照强度下，比较器的正输入的电压不同，根据比较后电压的正负值的不同，传输给单片机的信号也不同。单片机根据输入信号控制步进电机的旋转，一直达到所要求的范围为止。 The optimum tilt angle of PV modules Tracking System ABSTRACT Energy, also known as energy resources or energy resources, material resources for a variety of capacity and power for the production of human life. In a sense, the development of human society can not be separated from energy supply and use of advanced energy technologies. In todays world, the main energy supply is still mainly oil, coal and natural gas. With the continuous increase in the earths population, this type of energy being constant drain on the energy issue has become one of the human need to address an important focus. The new energy will be the main future human use. More and more people are looking to the huge solar energy, and ongoing research on the utilization of solar energy in order to expand the scope of application of solar energy.Over the past few years, Chinas domestic development and utilization of this one in the solar in the constantly accelerating, Chinas utilization of solar energy technology is still relatively backward compared to the foreign, and the scope of application of solar energy is also relatively narrow.This design covers the basic process principles, programming, PCB map, and the final test analysis. In this paper the working principle of the detailed overall analysis, describes the overall system design ideas. This design uses four photosensitive resistance induction under different light inten
