光伏一体化边坡风吸力特性的数值模拟研究

【摘要】 随着我国“双碳”目标的推进和交通基础设施绿色转型的深入，公路光伏边坡作为交通与新能源融合的重要形式，其抗风稳定性直接影响结构安全与发电效率。该研究基于ANSYS Fluent数值模拟软件，针对公路光伏一体化边坡的风吸力特性展开研究，通过建立3种不同坡率（1∶1.25、1∶1.5、1∶1.75）、3种不同风向角（0°、90°、180°）及8种不同风速工况下的模型，分析风速、风向、坡率对光伏一体化边坡风吸力的影响。研究结果表明，风速增加导致风吸力增大；风向角为90°时风吸力最大；增大坡率（坡度变缓）可有效降低风吸力。研究可揭示光伏一体化边坡的风吸力特性，提出公路光伏边坡的抗风优化策略，对提升公路光伏一体化工程在复杂风环境下的安全性和稳定性具有重要指导意义。更多还原

【Abstract】 With the advancement of China’s "double carbon" goals and the deepening of green transformation of transportation infrastructure, highway photovoltaic slopes are an important form of integration of transportation and new energy, and their windresistant stability directly affects structural safety and power generation efficiency. Based on the ANSYS Fluent numerical simulation software, the research conducted a study on the wind suction characteristics of highway photovoltaic-integrated slopes. By establishing models under 3 different slope ratios(1∶1.25, 1∶1.5, 1∶1.75), 3 different wind direction angles(0°, 90°, 180°) and 8 different wind speed conditions, the influence of wind speed, wind direction, and slope ratio on the wind suction of photovoltaic integrated slopes was analyzed. The research results show that the increase of wind speed leads to the increase of wind suction; the wind suction reaches the maximum when the wind direction angle is 90°; increasing the slope rate(the slope becomes slower) can effectively reduce the wind suction. The research reveals the wind suction characteristics of photovoltaic integrated slopes and proposes wind resistance optimization strategies for highway photovoltaic slopes, which has important guiding significance for improving the safety and stability of highway photovoltaic integrated projects in complex wind environments.更多还原
