光伏提水匹配模型与优化在西藏高原草场喷灌工程中应用——以阿里地区为例
|
摘要
以西藏高寒地区光伏提水草场喷灌为研究对象,利用噶尔站太阳辐射数据,构建日照分布函数模型及光伏阵列最大输出功率模型,计算出设计灌溉面积2.07 hm~2草场所需光伏阵列系统的峰值功率,为草场优化配置32块光伏板,即峰值功率为6.88 kW时,可以满足项目区生育期的灌水需求。工程应用表明:光伏匹配模型和优化计算所确定的光伏板数量和功率是可行的,能够驱动水泵正常运行,满足燕麦灌水需求。
This paper takes the sprinkler irrigation of photovoltaic water-raising grassland in the alpine region of Tibet as the research object,and uses the solar radiation data of Muir station to construct the sunshine distribution function model and the maximum output power model of the photovoltaic array in order to calculate the peak value of the photovoltaic array system required for designing the irrigation area of 2.07 hm2. The peak power is optimized for the grassland with 32 photovoltaic panels,it can meet the irrigation demands during the growth period of the project area. The engineering application shows that the number and power of photovoltaic panels determined by the photovoltaic matching model and optimization calculation are feasible,which can drive the pump to operate normally and meet the requirements of oat irrigation.
