山地大型柔性支架光伏阵列风场特性的数值模拟研究
STUDY ON NUMERICAL SIMULATION OF WIND FIELD CHARACTERISTICS OF LARGE-SCALE FLEXIBLE BRACKET PV ARRAYS IN MOUNTAINOUS AREAS
摘要
Abstract
In order to explore the influence of site terrain and large-scale PV arrays on the wind field characteristics of mountainous PV power stations,this paper takes the 100 m large-span flexible PV bracket demonstration project in Enping City,Guangdong Province as the research object.CFD method is used to carry out 3D numerical wind tunnel simulation calculations,establish mountain surface terrain models and large-scale PV array models of mountainous PV fields,and analyze the wind field environment of PV fields and the wind load characteristics of PV arrays using flexible PV brackets.The research results show that:1)The mountainous terrain in the direction of the incoming flow of the project site will block the incoming flow of the wind field,resulting in a significant decrease in wind speed and obvious mountain shielding effect.2)The wind load shape coefficient of PV modules under incoming flow direction of 0° and 180° in the south is significantly higher than that under incoming flow direction of 45° and 135°,indicating that the incoming flow direction has a significant impact on the wind load shape coefficient of PV modules.3)The wind load shape coefficient of the PV modules in the first row(column)on the windward side of the PV array is the highest,with a sharp decline in rows(columns)1～3,followed by a slow decrease and stabilization.The peripheral PV modules of the PV array have a significant shielding effect on the internal PV modules.The research results can provide guidance for the engineering design of flexible PV bracket structures and foundations in PV power stations,which is conducive to saving the engineering quantity of flexible PV brackets and its foundations in projects,and can provide a theoretical basis for the prevention and control of wind disasters,which is conducive to reducing the hidden dangers of wind-induced disasters in PV power stations.关键词
