摘要
Abstract
This paper aims to explore in depth the influence of spatial correlation of fluctuating wind on the wind induced vibration response of large-span PV arrays under flexible support systems.Taking a large-span PV power generation project using a flexible support system as the research object,a PV array model is established to analyze the wind induced vibration response of the PV array under the point wind source wind field and the wind field considering the spatial correlation with fluctuating wind direction.The displacement-time history response and wind induced vibration coefficient of the PV array are obtained.The research results show that:1)Under a flexible support system,the PV array exhibits a certain uniform stiffness distribution with an amplitude of about 14 cm,and the vibration is relatively stable.It is recommended to use a displacement wind induced vibration coefficient of 1.9.2)Compared with the case of point wind source wind field,in the wind field considering the spatial correlation with fluctuating wind direction,there is a phase difference in the displacement-time history response of the PV array,resulting in slight differences in the vibration characteristics at different positions of large-span structures,but the impact on safety indicators such as amplitude and wind induced vibration coefficient is negligible.In the safety research of large-span structures,point wind source wind fields can be used to simplify the workload without affecting the safety analysis of large-span structures.But if detailed research is needed on the vibration forms of specific points in large-span structures,it is necessary to comprehensively consider the influence of spatial correlation of fluctuating wind.关键词
