基于S7-200提高光伏发电系统效率研究

摘要

在研究光伏发电的背景基础上,设计出一种提高光电转换效率的光伏跟踪系统.该系统以西门子S7-200为主控制器,使光伏电池阵列能跟踪光源的移动、运动到与光源正对的位置,从而使光伏电池方阵获取最大的有效光照面积,达到提高光伏输出效率的目的.%Based on the research of the background of photovoltaic power generation, a photovoltaic tracking system for improving photoelectric transformation efficiency is designed.This system takes Siemens S7-200 as the primary controller, enabling the photovoltaic array to track the movement of the light source, and making the movement to an opposite position of the light source so that the photovoltaic cell array can obtain the maximum effective light area so to achieve the purpose of improving the efficiency of the photovoltaic output.
