摘要:

近年来山地光伏项目越来越多,为选择适合山地光伏电站的光伏阵列布置方法,基于数学建模的方法,建立了太阳光线、坡面和光伏组件的几何模型,推导出任意坡度和坡面方位角下使用随坡倾角布置和正南倾角布置的光伏阵列理论排间距计算方法,并通过设置判定条件使排间距的计算更加完善。对不同纬度、坡度、坡面方位角下的排间距进行分析,总结并对比了2种布置方法下排间距的变化规律和特点,为设计人员对光伏电站中光伏组件布置优化提供方向和理论基础。

关键词: 山地光伏电站, 随坡倾角布置, 正南倾角布置, 光伏阵列排间距

Abstract:

In recent years, there are more and more mountain photovoltaic projects. In order to select a suitable photovoltaic array layout method for mountain photovoltaic power stations, based on mathematical modeling, the geometric model of solar rays, slopes, and photovoltaic modules was established, the calculation methods for the theoretical row pitch of photovoltaic arrays at random slopes and azimuths were derived by using slope's azimuth-tilt layout and south-tilt layout, and the calculation of row pitch was more perfect by setting the judging conditions. By analyzing the results of row pitch under different latitudes, slopes, and azimuths on the slope surface, the rules and characteristics of the row pitch under the two layout methods were summarized and compared, which provided a direction and theoretical basis for designers to optimize the photovoltaic module layout in photovoltaic power stations.

Key words: mountain photovoltaic power station, slope's azimuth-tilt layout, south-tilt layout, row pitch of photovoltaic array
