摘要
根据产业政策和车辆基地特点,对分布式光伏发电技术在轨道交通的应用现状、光伏组件的安装方式、不同年辐照量等级区域的发电量、成本以及静态投资回收期、并网方式以及发展方向进行了分析和研究.结果表明:BAPV安装方式适用于车辆基地大库、高架站屋面以及轨道交通沿线边坡,BIPV安装方式适用于对外立面效果要求高的综合楼、办公用房以及规模大的站房、雨棚等建构筑物.通过案例计算,年辐照量A级区域最小静态投资回收期为8.13年;年辐照量B级区域最小静态投资回收期为 10.23年;年辐照量C级区域最小静态投资回收期为 13.80 年.A、B、C各区域最大静态投资回收期均小于光伏组件的功率质保期.不同项目车辆基地分布式光伏发电系统发电量和成本测算时,可结合项目自然环境条件、当地电价以及车辆基地大库布置方案等各方面因素,参照本文计算方法进行测算.
Abstract
Based on the industrial policy and characteristics of vehicle depot,the analysis was conducted on the current application status of distributed photovoltaic technology in rail transportation,including installation methods of photovoltaic modules,electricity generation,costs in regions with different annual irradiation levels,static investment payback period,grid connection methods and development directions.The results indicate that the BAPV installation method is suitable for vehicle depot warehouses,elevated station roofs,and slopes along rail transit lines.While the BIPV installation method is suitable for comprehensive buildings with high requirements for external facade effects,office buildings,as well as large-scale station buildings,canopies,and other structures.Based on the case calculations,the minimum static investment payback period for A-grade areas with annual irradiation is 8.13 years,for B-grade areas it is 10.23 years,and for C-grade areas it is 13.80 years.The maximum static investment payback period for each region is lower than the power warranty period of the photovoltaic modules.When calculating the electricity generation and costs of distributed photovoltaic systems for different project vehicle depot,various factors such as natural environmental conditions,local electricity prices,and the layout plan of the large base can be considered and calculated using the methods described in this paper.
