摘要

太阳能光伏发电已成为全球绿色能源开发利用的重要组成部分,拉索式架构体系光伏电站由于诸多优点备受关注。风是光伏电站架构体系中光伏板的重要荷载因素,采用二维计算流体动力学数值模拟技术研究阵列排放光伏板的风荷载特性,针对正向风载、背向风载两种极限工况,分析了光伏板倾角、板间距和板高度等因素对光伏板的风荷载及其折减特性的影响。相关分析方法和结论可为光伏电站架构体系的结构强度设计提供载荷依据。

Abstract

The solar photovoltaic power generation has become an important part of the green energy development and utilization in the world.The cable structural system of photovoltaic power station has been focused because of many advantages.Wind can bring about the main load acting on the photovoltaic panels of photovoltaic power station.The two-dimensional Computational Fluid Dynamics (CFD) numerical simulation technology is adopted to analyze the wind load characteristics of arrayed photovoltaic panels.For two kinds of extreme conditions,which are the loaded cases of forward wind and backward wind,the wind load and its reduction characteristics are analyzed in the investigation considering the effects of the photovoltaic panel angle,distance between panels and height of panels.The analysis method and correlative conclusion are helpful to the structural strength design of photovoltaic power station.
