【摘要】 以河西走廊已投运的30个光伏电场为研究对象,提出由光伏面板集雨面、集流管槽、输水管、蓄水池四部分组成的光伏电场雨水集蓄系统,并利用当地气象、水文资料,分别计算了不同降雨量条件下武威、张掖、嘉峪关三个地区50 MWp光伏电场可收集雨量,1、0.1 MWp光伏面板雨水收集单元适宜的收集管管径、蓄水池容积等。结果表明,在年降雨量小于100 mm的嘉峪关地区,单个50 MWp光伏面板年收集雨水量理论计算值可达到2.3万m~3,对于该部分雨水资源的利用具有重要意义。更多还原

【Abstract】 We took 30 photovoltaic fields in Hexi Corridor as the research object and proposed the rainwater collection system for photovoltaic electric field which consisting of photovoltaic panel collecting surface, collecting tube groove, collecting tube and cistern. We had also calculated respectively the collectible rainfall of 50 MWp photovoltaic farms in Wuwei, Zhangye and Jiayuguan under different rainfall conditions as well as the suitable diameter and reservoir volume for collection pipe in rainwater collection unit 1 MWp and 0.1 MWp of photovoltaic panel. The result shows that even in Jiayuguan, of which the annual rainfall is less than 100 mm, the theoretical value of annual rainwater collection can reach more than 2.3×10~4 m~3. It is worth paying attention to the use of rainwater resources in this area.更多还原
