青海省光伏电站的积尘及清洁效果调查与研究

Investigation on the Dust Accumulation Characteristics and Cleaning Effect of PV Power Stations in Qinghai Province

受沙尘影响,光伏组件表面经常性形成严重的积尘,对电站的运维管理和运行效益产生较大影响。为了解青海不同地区的积尘形式、清洗方式以及应用效果,在青海省海南州进行了调研,对电站的积尘特点、清洗方式、清洗效果、清洗成本等内容开展调查和研究。研究结果发现,通过自然降水和人工清洗都可以得到较好的清洁效果,两种清洁方式分别可平均提升发电量为3.49%和7.83%。

Due to severe dust accumulation on PV module surfaces,which has a significant impact on the efficiency of the power station.In order to understand the dust accumulation characteristics in various areas,as well as the application of different cleaning effects,an investigation and research were carried out in Hainan Prefecture,Qinghai Province.Which focused on the dust accumulation characteristics,cleaning methods,cleaning effect,and cleaning costs of the power stations.The results of the study found that both natural precipitation and artificial cleaning method can be obtained great cleaning effects.Those two cleaning methods can increase electric energy by 3.49%and 7.83%,respectively.
