摘 要：本文采用《光伏发电站设计规范》GB 50797—2012 中的计算方法，确定光伏组件不同安装倾角下方阵间距，并利用 PVsyst 软件建模，对光伏系统进行仿真，得出光伏组件在不同安装倾角下光伏系统发电量; 由《光伏发电系统效能规范》NB /T 10394—2020 中的方法计算出项目的平准化度电成本( LCOE) ，LCOE 最小，则对应光伏组件的安装倾角最适合该项目。

Abstract:In this paper，the calculation method in “Code for design of photovoltaic power station”GB 50797 － 2012 is adopted to determine the square spacing of photovoltaic modules under different installation angles，and PVsyst software is used to model and simulate the photovoltaic system，and the photovoltaic system energy generation under different installation angles is obtained． The normalization kilowatt-hour cost ( LCOE ) of the project is calculated by the method in the “Specification for Photovoltaic Power Generation System Performance”NB /T 10394－2020． If the LCOE is the smallest，the installation Angle of the corresponding photovoltaic module is the most suitable for the project．
