沙漠光伏电站地表蚀积发生机制实验研究
Wind tunnel experiment and numerical simulation of surface erosion and accumulation in desert photovoltaic power stations
摘要
Abstract
Wind-sand activities cause surface erosion or accumulation,affecting the safe operation of photovolta-ic power plants.This study analyzed the field characteristics of wind speed flow and the erosion variation of pho-tovoltaic panels under different wind speed conditions(6,8,and 10 m·s-1)through wind tunnel experiments and numerical simulations to elucidate the mechanism of surface wind erosion in desert PV power plants.The re-search results revealed that(1)photovoltaic panels change the near-surface wind speed and flow field,forming a front plate airflow lifting zone,a bottom plate airflow acceleration zone,a back plate vortex deceleration zone,and a tail plate airflow recovery zone;the wind speed near the surface of the board significantly increases,making it prone to erosion,while the wind speed behind the board decreases,making it prone to accumula-tion.(2)when the wind direction is reversed,the"narrow tube effect"under the photovoltaic panel leads to increased airflow,and wind erosion is significantly greater than normal airflow.The accumulation behind the panel is related to the deceleration of the vortex on the leeward side.(3)the wind erosion under the edge ar-ray panel of the photovoltaic power station is the most severe,while the wind erosion inside the power sta-tion array is relatively light;as the height of the photovoltaic modules increases,the wind erosion under the panels is reduced to some extent.The results provide a scientific basis for sand hazard prevention and efficient production of desert photovoltaic power plants.关键词
