摘要
随着光伏装机容量的不断增长与国家补贴的逐步取消,光伏安装效益及运行状况的研究对提高光伏效益具有重要意义。为提高光伏安装效益,提出综合考虑风速、倾角、间距及光伏板面积之间的相互影响的优化模型。针对光伏阵列故障排查与积灰清理不及时导致光伏发电效率降低的现状,提出一种基于低成本监控系统的光伏运行诊断方式,提高了光伏发电效率。以盐城市响水县1.5 MW光伏电站为研究对象,通过对光伏电站实际数据的分析,验证了所提理论的准确性。
Along with continuous growth of photovoltaic(PV)installed capacity and gradual elimination of state subsidies,research on PV installation benefit and operational state is of great significance to the improvement of PV benefits.In order to improve PV installation benefit,an optimization model was proposed under overall consideration of mutual influence among wind speed,inclination,distance and PV panel area.In view of reduced PV generation efficiency caused by untimely PV array troubleshooting and dust clearing,a PV operation diagnosis method was proposed on the basis of a low-cost monitoring system to improve PV power generation efficiency.Taking a 1.5 MW PV power station in Xiangshui county,Yancheng city as the research object,the accuracy of the proposed theory was verified through analysis of the actual data of the PV power station.
