摘要:

通过研究山地光伏阵列间距计算与坡度、坡向之间的关系,在平地光伏阵列间距数学计算模型的基础上加以改进推导,得到一种适用于山地光伏项目中光伏阵列间距的数学模型计算方法,并且通过该方法得到了不同坡度情况下,光伏阵列间距随坡向变化的规律。该方法不仅有利于全方位了解山地光伏项目不同地形的光伏阵列间距,便于更精准地评估不同朝向地块的可利用性,而且能为今后的山地光伏项目前期选址及设计阶段经济性优化比选提供一种切实有效帮助。

Abstract:

Studying the relationship between the spacing of PV arrays in mountainous areas, the gradient and the direction of slopes, improvement can be made on the base of mathematical calculation model of the spacing for plain PV arrays, and a mathematical model calculation method suitable for the spacing for PV arrays in mountainous PV projects is obtained. Through this method, the regularity of PV array spacing varying with the slope direction is obtained under different slope conditions. This method is not only conducive to a comprehensive understanding on the PV array spacing of mountain PV projects with different topographies, but alsoconducive to a more accurate assessment of the availability of terrains with different direction, which can provide a practical and effective assistant for the future site selection for mountain PV project at a early stage and the economic optimization at design stage.
