摘　　要：复杂地形风电机组建设时易形成高边坡地形,可能严重影响机组的发电量和疲劳寿命。以重庆市某复杂山地风电场为例,基于CDRFG(Consistent Discretizing Random Flow Generation)方法生成大气边界层湍流入口,采用大涡模拟技术重现高边坡复杂地形的湍流风场分布,并根据激光测风雷达和测风塔实测数据验证大涡模拟结果的准确性;对比分析了风机平台开挖导致的3种不同高边坡地形下,风机机位湍流风场的差异性,提出了风机平台开挖影响评估指标,深入分析了高边坡地形对风电机组发电效益和安全运行的影响。研究为复杂地形风机平台建设提供了科学保障。The construction of wind turbines in a complex terrain is prone to a high slope one,which may seriously affect the power generation and fatigue life of the turbines.Based on the Consistent Discretizing Random Flow Generation(CDRFG)method to generate turbulent inlet at the atmospheric boundary layer,a complex terrain wind farm in Chongqing City was used to reproduce the turbulent wind field distribution in the high-slope complex terrain,and the accuracy of the large eddy simulation results was verified upon laser wind measurement radar and wind measurement tower data.The differences of turbulent wind field at the turbine site under the high-slope terrain of three different turbine platform excavations are compared and analyzed,and several indices are proposed to assess the impact of wind turbine platform excavation.Moreover,the impact of the high-slope terrain on the power generation efficiency and safety of the turbine is analyzed in depth.The study provides a scientific guarantee for the construction of wind turbine platforms in complex terrains.
