摘　　要：为了保证风电机组定场址安全性复核时对边界条件的正确选取,更好地保障机组的安全性,基于Bladed软件,以某双馈风力发电机组为例,分析不同风切变、入流角和对风误差等风况特性对风力发电机组关键部位载荷的影响。研究结果表明,叶片摆振与塔架俯仰载荷对对风误差、风切变与入流角敏感度较低,而叶片挥舞与塔架倾覆载荷受对风误差、风切变与入流角影响较大,并且随着风速的增大影响变大。此研究结果能为机组安全性复核时计算边界条件的选取提供一定的依据。In order to ensure the correct selection of boundary conditions in site safety check of wind turbine and better guarantee the safety of the wind turbine,taking a doubly fed wind turbine as an example based on Bladed software,the influence of different wind shear,inflow angle and wind error on the key load of the wind turbine was analyzed.The results show that the blade shimmy and tower pitching loads are not sensitive to the wind error,wind shear and inflow angle,while the blade waving and tower overturning loads are greatly affected by the wind error,wind shear and inflow angle,and the influence increases with the increase of wind speed.The results can provide some basis for the selection of boundary conditions in the site safety check.
