Résumé partiel
With the increase in global energy demand and the shortage of fossil energy,renewable energy sources such as solar,wind,and hydropower have attracted more and more attention.Many desert areas in Northwest my country,with abundant solar irradiance and cheap land resources,are very suitable for the construction of large-scale photovoltaic power stations.However,the harsh climate conditions in Northwest China will have a negative impact on the power generation efficiency of photovoltaic modules.Especially,the deposition of sand particles on the surface of photovoltaic panels will greatly reduce the power generation efficiency of photovoltaic modules.At present,the development prospects of technologies for improving the utilization rate of solar photovoltaics have been limited,and people have turned their attention to how to improve the operation of photovoltaic systems and the maintenance of photovoltaic modules in the later period.In this paper,the surface settlement distribution of photovoltaic panels is simulated and analyzed by numerical simulation.As the wind field around the photovoltaic module and the sand settling process will have an impact on the sand settling on the surface of the photovoltaic panel,these two aspects are studied and analyzed in the previous paper.The main contents of the article are as follows:Firstly,the relevant research status is summarized and analyzed.In addition,taking a photovoltaic module in a photovoltaic power station in Zhongwei as a model,the DPM model was used to analyze the flow field distribution around the photovoltaic panels,and the effects of incoming wind speed,incoming wind direction and photovoltaic panel height on the wind speed profile between photovoltaic panels were simulated and analyzed.
