光伏组件倾角和阵列间距的多因素综合计算方法

Multiple factors integrated computing method to determine angle and array spacing of PV modules

合理确定光伏电站组件的安装倾角和阵列间距,对提高光伏电站发电效益至关重要。综合考虑了组件全年运行时间内的阴影损耗、光伏发电单元直流电缆用量、直流电缆线损、光伏阵列占地面积多因素,提出了一种确定组件的安装倾角和阵列间距综合的计算方法,以追求发电效益最大化。该方法在提高发电量的基础上,实现了光伏电站的"紧凑化"设计,不仅节省了单位兆瓦光伏发电单元的占地面积,提高了土地利用率,且增加了发电效益。

The reasonable determination of the angle and array spacing of PV station module is crucial to the improvement of generation benefit. By comprehensive consideration on the multiple factors of the annual shadow loss, the amount of DC cable, DC cable loss and the land occupied by the PV plant, a kind of integrated computing method to determine the angle and array spacing of the modules is presented for pursuing the maximum efficiency. Besides the increase of the generation capacity, the compact design of PV power＇station is realized, which saves the area covered by PV power generation unit per MW and increases the land utilization rate.
