风向角和安装倾角对海上固定式光伏风荷载的影响
Influence of wind direction and installation angles on offshore fixed photovoltaic wind loads
摘要
Abstract
The growing demand for renewable energy combined with limited land resources has driven the devel-opment of marine-based photovoltaics,thereby placing greater demands on the structural safety of photovoltaic(PV)platforms.The wind load,which is the main force acting on offshore fixed PVs,plays a crucial role in ensuring the safe operation of the PV structure.In this study,we propose a type of fixed offshore PV support that employs com-putational fluid dynamics combined with a Reynolds-stress turbulence model to analyze the flow field under wind load.We examined the flow-field characteristics around the PV platform at varying wind direction angles and in-stallation angles.The results demonstrate that at a wind direction angle of 0°,the lift coefficient of the structure decreases as the installation angle increases,and the resistance coefficient reaches its minimum value at an installa-tion angle of 10°.At a wind direction angle of 90°,both the lift and drag coefficients remain largely unaffected by changes in the installation angle.However,when the wind direction angle is 180°,the lift coefficient increases,making the structure more prone to overturning.At this angle,both the lift and drag coefficients reach their maxi-mum values at an installation angle of 10°.This study provides valuable data and theoretical insights for the design and optimization of offshore fixed PV supports,providing substantial engineering and practical value for real-world applications.关键词
