摘  要:高架车站一般位于郊区,周边无遮挡,有大面积屋面可进行光伏板敷设,选取典型高架车站的屋面进行光伏系统设计后计算逐时发电量,并利用EnergyPlus对站厅层逐时空调能耗、照明能耗进行计算,通过对比,得出光伏系统为空调系统供电,全年仅12.7%的小时数出现发电量富余,若包括照明系统,该小时数则缩短为7%,即光伏发电量绝大部分逐时自发自用,因此高架车站无需设置造价昂贵的蓄电池,而且光伏发电系统能有效减缓用电高峰。最后通过经济性分析,在不考虑任何补贴的前提下,高架车站设置光伏发电系统仅需13 a即可达到静态回收期,25 a周期减排经济效益达37万元。Generally,the elevated station is located in the suburb,without shelter in the surrounding area,and photovoltaic panels can be laid on large areas of roof. This research selected the roof of a typical elevated station for photovoltaic system design and calculated hourly power generation. According to the comparison,the photovoltaic system supplies power for the air-conditioning system,only 12. 7% hours of the year appear have a surplus of power generation,which is shortened to 7% if the lighting system is included,that is,most photovoltaic power generation is consumed,so the elevated station need not set up the expensive battery,and the photovoltaic power generation system can effectively reduce the peak of power consumption. Finally,according to the economic analysis,the photovoltaic power generation system in the elevated station can reach the static payback period in only 13 years, and the economic benefit of the 25-year emission reduction is up to 370,000 yuan without any subsidies considered.

关 键 词:高架车站 光伏发电 空调能耗 回收期
