风速、风向对空载光伏组件温度分布影响的数值分析
Numerical analysis on the temperature distribution characteristics of photovoltaic module with velocity variation and wind direction variation
摘要
太阳能电池将光能转化成电能技术在世界上广泛应用。文章采用CFD方法对不同风速、风向下光伏组件温度分布进行研究;建立了9块一列的光伏组件模型,朝向正南,倾角为30 的数值计算模型;运用Fluent软件的DO模型、日光计算器等建立辐射模型。数值模拟结果显示:在西北风作用下,光伏组件各个组成部分,即玻璃板、电池片、背板温度分布走向基本一致;9块光伏组件温度自西向东逐渐升高;在风速相同的情况下,不同风向对光伏组件温度分布有着直接影响,正南风与光伏组件朝向相同,有利于光伏组件的散热;当风向一定时,加大风速有利于光伏组件的散热。
Abstract
The technology of converting light into electrical energy with solar cells is widely used in the word.In the paper,use CFD software do the numerical analysis on the temperature distribution characteristics of photovoltaic modules with velocity variation and wind direction variation;establish dynamic model of nine photovoltaic modules with angle of 30 degrees toward the south in a line;Use the DO model and solar calculator to establish radiation model.The simulation results show: under the action of the northwest wind, the temperature distributions of photovoltaic comopnent parts are the same;the temperature of nine photovoltaic modules rises from the west to the east;under the same velocity,different wind direction has directly influence on the temperature distribution ot photovoltaic modules,the south wind is conducive to heat disspation of photovoltaic modules;when the wind is a fixed value, the high velocity is advantageous to the photovoltaic modules cooling.关键词
