光伏方阵场设计与应用

Design and Application of Photovoltaic Square Array Field

"十三五"时期是我国能源低碳转型的关键期,供暖热源和形式也趋于多样化,其中电供暖为消纳和发展光伏发电带来新的契机。本文阐述了光伏方阵场的设计要点,包括光伏组件的选择,光伏阵列最佳倾角的优化,支架安装方式选择,光伏组件串的串联数和光伏组件间距的计算等。以泰来县光伏发电项目为例,通过设计光伏方阵场,说明了以上要点对太阳能辐射接收量和系统发电量的影响,分析了项目的经济性。

The“Thirteenth Five-Year Plan”period is the critical period of energy and low-carbon transformation in China.Heat sources and forms tend to be diversified,among which electric heating brings a new opportunity for consumption and development of photovoltaic power.In this paper,the key points of designing photovoltaic square array are described,including selection of photovoltaic modules,optimization of the inclination of photovoltaic arrays,selection of mounting methods,calculation of the series number of photovoltaic modules and the distance between photovoltaic modules,etc.Taking the photovoltaic power generation project in Tailai County as an example,the influence of the above key points on the solar radiation receiving quantity and the power generation of the system is explained by designing photovoltaic square field,and the economy of the project is analyzed.
