摘　　要：以陕西省某光伏电站为例,通过PVsyst软件模拟分析了该光伏电站采用平单轴跟踪支架时,支架东西向间距对光伏电站年发电量的影响及相关的变化趋势。在光伏电站全寿命周期内,对平单轴跟踪支架东西向间距不同时电站的投资总费用和年发电收益进行了计算,采用差额内部收益率法得出了最优的支架东西向间距。此计算方法可为工程建设中平单轴跟踪支架东西向间距的优化提供参考。Taking a PV power station in Shaanxi Province as an example,the PVsyst software is used to simulate and analyze the impact of the spacing in east-west direction for the horizontal single-axis tracking bracket on the annual power generation and the related change trends of this PV power station.During the whole life cycle of the PV power station,the total investment cost and power generation income of the power station with different spacing in east-west direction for the brackets are calculated,and the difference internal rate of return method is used to obtain the optimal east-west direction spacing for the brackets.This calculation method can provide a reference for the optimization of spacing in east-west direction for horizontal single-axis tracking bracket in engineering construction.
