摘　　要：为研究斜坡地形对光伏组件风振特性影响,基于流固耦合(FSI)方法开展光伏阵列风致响应的数值模拟研究,分析光伏阵列流场特征以及光伏组件风振响应模态,揭示位于不同坡度斜坡上的光伏组件在不同离地高度、间距上所表现出的风振特性。结果表明:1)坡面引起气流堵塞,致使光伏组件位移幅值增加,同时也降低光伏阵列中前排光伏组件对后排光伏组件的遮挡效应;2)从流场特征中可看出,迎风前缘的首块光伏组件产生旋涡,脱落于后排区域,致使第2块光伏组件前流场变得复杂,第3块光伏组件周流场则相对稳定,说明越处于下游的光伏组件受流场影响越小;3)光伏组件的振动由低阶振型主导,坡面对后排光伏组件振动有较大影响;4)间距增大对位于坡面上的光伏阵列振动响应有影响,且随着坡角的增大影响更加显著;5)增加坡面上光伏阵列的高度,首块光伏组件位移幅值变化较为明显,其余两块光伏组件影响较小。In order to investigate the influence of sloping landform on the wind-induced vibration characteristics of solar panels,this study conducted a numerical simulation of the wind-induced response of a solar array based on FSI(fluid structure interface).The flow characteristics of the solar array and the modal response of the solar panels were analyzed,and the wind-induced vibration characteristics of solar panels located on slopes with different inclinations at different heights and spacings were revealed.The results show that:1)The slope causes airflow blockage,which increases the displacement amplitude of the solar panels,and also reduces the shielding effect of the front-row solar panels on the rear-row solar panels;2)From the flow characteristics,it can be seen that the first solar panel at the windward edge generates a vortex,which detaches in the rear area,making the flow field in front of the second solar panel complicated,while the flow field around the third solar panel is relatively stable,indicating that the more downstream the solar panel is,the less it is affected by the flow field;3)The vibration of the solar panels is dominated by low-order modes,and the slope has a significant impact on the vibration of the rear-row solar panels;4)Increasing the spacing has an impact on the vibration response of the solar array located on the slope,and the impact becomes more significant with the increase of the slope angle;5)Increasing the height of the solar array on the slope,the displacement amplitude of the first solar panel changes significantly,while the impact on the other two solar panels is relatively small.
