摘要
针对复杂地形光伏场地的固定式光伏阵列间距进行了研究,分别建立了光伏场地为平地、南坡、北坡时的光伏阵列间距计算模型,对光伏场地的坡度、方位角与光伏阵列间距之间的关系进行了分析;然后推导出任意坡度及光伏场地方位角光伏阵列间距计算模型,仅用1个公式即可概括计算;最后采用CAD及SketchUp软件对该计算模型的准确性进行了验证。由于光伏场地方位角的特殊性,在其为南偏西或北偏西的情况下,固定式光伏阵列间距应以当地真太阳时09:00为准计算;在其为南偏东或北偏东的情况下,固定式光伏阵列间距应以当地真太阳时15:00为准计算;计算模型具有对称性。研究结果可为复杂地形光伏场地的光伏阵列间距设计提供参考计算公式。
This paper focuses on the study of fixed PV array spacing in complex terrain PV field areas.Calculation models for PV array spacing when the PV field area is flat ground,southern slope,and northern slope are established,and the relationship between the slope,azimuth angle,and PV array spacing of the PV field is analyzed.Then derive a calculation model for the spacing between PV arrays at any slope and any azimuth angle of PV field area,which can be summarized and calculated using only one formula.Finally,the accuracy of the calculation model is verified using CAD and SketchUp software.Due to the particularity of the azimuth angle of PV field area,in the case of south by west or north by west,the distance between fixed PV arrays should be calculated based on 09:00 local real solar time.In the case of south by east or north by east,the distance between fixed PV arrays should be calculated based on 15:00 local real solar time.The computational model has symmetry.The research results can provide reference calculation formulas for the spacing design of PV arrays in complex terrain PV field areas.
