光伏电站中可调支架系统经济技术分析

摘要

通过建立太阳能辐射数据库,优化可调光伏支架的接收角度,以提高光伏系统发电效率,改善传统的固定倾角支架和自动跟踪支架模式.文章以沈阳地区10 MW并网电站为例,比较了每年以不同次数手动调节支架与固定倾角支架的发电量.经济技术分析显示,每年调整支架倾角12次的年发电量最多,每年调整倾角4次的经济效益最好.%In this study, by creating a solar energy radiation database and optimizing the receiving angle of adjustable PV bracket, the PV system power generation efficiency is increased, traditional fixed dip and automatic tracing bracket mode is improved. Taking a 10 MW grid-connected power station in Shenyang as an example, the generating capacities of each year are compared between the PV power station with manual adjustable bracket and the one with fixed inclination bracket. And the economic and technological analysis results show that adjusting the angle of 12 times is the most generating capacity of each year and adjusting the angle of 4 times is the best economic benefits.
