摘要
西藏地区拥有丰富的太阳能资源和土地资源,可满足建设大型光伏发电站的空间需求,具有巨大的发展潜力,因此设计适应西藏高海拔高寒特殊场景的光伏电站便成为研究的重点。以西藏拉妥一期700 MW光伏发电项目为例,从光伏主要设备选型、利用Pvsyst组件优化安装倾角、组串及间距计算等方面对光伏电站进行设计,得到了适宜的高海拔高寒地区光伏电站系统设计方案,以期为光伏电站在高寒地区的实际应用提供理论参考。建成的光伏电站预计每年可为电网提供电量140100.67万kWh,相当于节约标煤炭45.53万t,可显著减少大气污染物排放,具有明显的社会效益和经济效益。
Xizang has abundant solar energy resources and land resources,enough to meet the space needs of the construction of large-scale photovoltaic power stations,with great development potential.The design and study of photovoltaic power stations adapted to the special scene of high altitude and cold in Xizang has become an important topic for technical personnel to study.This paper takes the 700 MW photovoltaic power generation project of Latul Phase I in Xizang as an example,and designs photovoltaic power stations through the selection of photovoltaic main equipment,the optimization of installation inclination angle by pvsyst module,and the calculation of series and spacing.The suitable design scheme of photovoltaic power station system in high altitude and cold area is obtained,in order to provide theoretical reference for the practical application of photovoltaic power station in high cold area.The completed photovoltaic power station is expected to provide 1401.067 million kWh of power generation for the power grid every year,equivalent to saving 455300 tons of standard coal,which can significantly reduce the emission of atmospheric pollutants,and has obvious social and environmental benefits.
