基于GIS+Fluent的复杂山体柔性光伏工程风速修正系数研究
Study on the Wind Speed Correction Coefficient of Flexible Photovoltaic Projects in Complex Mountainous Areas Based on GIS+Fluent
摘要
Abstract
With the rapid development of the photovoltaic industry,the shortage of land resources has become more and more prominent,making it an inevitable trend for the photovoltaic industry to"move to mountains and seas".The large-span photovoltaic support has in-herent advantages in adapting to complex terrains.However,complex mountainous areas have completely different wind field characteris-tics from those of a single mountain.The distribution of the near-surface wind field in complex terrains is highly non-uniform,and the range represented by the observation data is very limited.Therefore,it is particularly important to use the numerical wind tunnel simula-tion method to obtain the high-resolution distribution of the near-surface wind field under complex terrain conditions.In order to obtain the distribution law of the high-resolution near-surface wind field of flexible photovoltaics in complex mountainous areas,based on the GIS(Geographic Information System)and the FLUENT numerical analysis software,taking the site of an actual flexible photovoltaic support project in Baishui County,Shaanxi Province as an example,this paper analyzes and studies the distribution characteristics of the wind field and the wind speed correction coefficients at 11 key positions under 8 different wind direction angles in different wind conditions in complex mountainous terrains.The results show that the wind conditions with the wind direction angles of ES135° and NW315° are the most severe,with the maximum value of 1.45.When the wind direction angle is consistent with the direction of the valley,the valley acceleration effect is likely to occur.The wind speed correction coefficients at different positions of the photovoltaic site are significantly different,ranging from 0.34 to 1.45.The research results can provide a reference for the determination of the wind speed values in flexible photovoltaic projects in mountainous areas.关键词
