摘要
目前存在大面积光伏阵列建设在山坡上,其所处山坡地形下的风环境与平地的风环境区别较大,但针对不同山坡地形下光伏阵列的风荷载干扰效应研究鲜有涉及。通过刚性模型测压风洞试验的方法,对0°风向角下,不同山坡坡度、不同倾角的2列3排的光伏板阵列进行风荷载分析对比。结果表明:相比于平地光伏阵列,山坡光伏阵列的光伏板所受风荷载并未因所处海拔高度变高、接触来流风风速增加而变大,反而有所减小;当坡度为30°时,山坡地形的光伏阵列中各板风荷载大小关系与平地的不同。研究成果可为山坡地形的光伏阵列的设计提供参考建议。
At present,lots of photovoltaic arrays have been constructed on hillsides,and the wind environment of the hillside terrain where arrays located differs greatly from that of flat land,but little research has been done on the wind load interference effects of photovoltaic arrays under different hillside terrains.By means of rigid model piezometric wind tunnel tests,wind load analysis is conducted for two rows of three PV arrays with different slopes and inclination angles under 0°wind angle.The results show that the wind load on the panels of the hillside PV arrays does not increase due to the higher altitude and higher wind speed in contact with the incoming wind,but decreases compared with that of the flat ground PV arrays.When the slope is 30°,the wind load of each plate in the photovoltaic array of the hillside terrain is different from that of the flatland.The research results can provide reference suggestions for the design of photovoltaic arrays on hillside terrains.
