Abstract

The characteristics of wind speed fluctuation under the disturbance of photovoltaic panels in sandy area were studied,and the law of wind erosion and sand burial at the photovoltaic power station was revealed. The study is of a theoretical foundation for preventing and controlling sand disasters at the photovoltaic power station in sand area. Two sections at the eco-photovoltaic power station were selected,and the values of wind speed at 20,50,80,100 and 200 cm heights and the typical positions of the panel arrays were are measured. The wind speed fields at the station were analyzed. The results showed that:① Wind speed at the photovoltaic panel margin was the highest,the anode wind speed was significantly reduced,and the wind speed after the arrays was gradually reduced,especially near the ground surface. The average wind speeds 20 cm under the panels,at the front and between the panels were increased by 44.7%,54.8% and 7.2% respectively; ② The wind speed fluctuation and intensity at three locations of the PV panels were decreased at first and then increased with the increase of height,and the turbulence was the most serious at the height of 20-80 cm. Compared with the contrast,the turbulence under the photovoltaic panels and at the front of panels was increased with the increase of height;③ The fluctuation of wind speed around the photovoltaic panels was the main driving force for forming the vortex under the panels and at the front of panels,which resulted in the erosion of the photovoltaic base and the development of the sand belt between the panels.
