复杂工况下柔性光伏支架阵列风荷载特性及其遮挡效应
Wind load characteristics and shielding effects of flexible photovoltaic support array under complex conditions
摘要
Abstract
Flexible photovoltaic(PV)support structures are inherently sensitive to wind forces,and this study aims to systematically investigate their wind load characteristics and shielding effects under complex condi-tions,employing both experimental and computational methods.Initially,a rigid model of a flexible PV sup-port structure array consisting of two spans and seven rows is designed and fabricated for wind tunnel testing.The influence of various parameters,such as wind direction angle and module tilt angle,on the wind load shape coefficient of the array is examined,with particular emphasis on the shielding effects of the PV mod-ules.Subsequently,computational fluid dynamics(CFD)simulations are conducted to further analyze the ef-fect of inter-row spacing on the wind load characteristics of the array.Finally,recommendations for the reduc-tion factors of the wind load shape coefficient in flexible PV support structures are provided.The findings re-veal that the most critical wind direction angles are 0° and 180°,where the wind load is most severe.The abso-lute value of the wind load shape coefficient increases with the module tilt angle,peaking at 1.30 when the tilt angle reaches 40°.Increasing the inter-row spacing generally enhances the wind load shape coefficient of the flexible PV array,though it exerts minimal influence on the reduction factor.For a 0° wind direction angle,a reduction factor of 0.6 is applicable when the module tilt angle is less than 25°,while a reduction factor of 0.5 is recommended for tilt angles greater than or equal to 25°.Under a 180° wind direction angle,a uniform re-duction factor of 0.5 is suggested.关键词
