Design of array spacing for photovoltaic power station on northern slope area

研究了大型地面电站和屋顶光伏电站在北坡场地建设时的光伏阵列间距设计,根据具体坡度、地势、建筑物方位角等进行了阵列间距的优化设计。通过一般阵列间距计算公式,计算了北半球不同纬度的日照间距系数,分析了场地坡度与光伏阵列间距之间的关系,推导了北坡场地光伏阵列间距设计的理论计算方法,针对类似的大型地面电站提出了阶梯式阵列设计方法。

The photovoltaic array spacing design for large-scale above-ground PV power station and housetop PV power station built on northern slope area was studied.Based on the concrete gradient,the terrain and the azimuth angle of buildings,an optimized design of PV array spacing was given.By means of general array spacing calculating formula,the coefficient of sunshine spacing at different latitude of the Northern Hemisphere was calculated.The relation between the field gradient and the PV array spacing was analyzed.The theoretic calculation method of PV array spacing design for northern slope area was deduced.Aiming at similar large-scale above-ground power station,a multistep array design method was proposed.
