中文摘要	研究沙区光伏电板扰动下风速脉动特征,掌握光伏电站风蚀沙埋规律。本文选取生态光伏电站内2个断面,对电板阵列板下、板前以及板间等典型部位20、50、80、100、200 cm的5个高度风速进行测定,分析光伏电站的风速流场、脉动特征。研究结果表明:①光伏电板上风向边缘风速最大,经过阵列逐渐减弱,光伏电场阵列腹部风速明显降低,尤其在近地表层,相比电板阵列腹部平均风速,板下、板前、板间20 cm平均风速增加了44.7%、54.8%和7.2%。②光伏电板上风向3处风速脉动、风速脉动强度表现为随高度增加呈先降低后增加的趋势,腹部电板随高度的增加呈降低趋势,其中20~80 cm湍流度最为剧烈;与对照相比,光伏电板上风向边缘处湍流度在板下、板前位置随高度呈增强趋势。③光伏电板周围的风速脉动是形成板下和板前涡流的主要动力,进而造成光伏基座掏蚀与板间积沙带的发育。
英文摘要	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 20,5 0,80,1 00 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.
