摘　　要：针对大型风力发电机组设计中的风速条件进行了模拟研究,利用Bladed软件进行了仿真和载荷计算,研究内容包括风切变、塔影、上风向尾流、三维湍流、瞬时风速等建模问题。结合沈阳工业大学承担"863"项目——SUT-1000 MW级变速恒频风电机组的研制,进行了IEC标准下各级负载级别的载荷计算。Wind condition simulation of large-scale wind turbine design was studied in this paper, and the load calculation based on Bladed software was introduced. The content includes modeling of wind shear, tower shadow, upwind turbine wake, three dimensional turbulence and time varying wind etc. Later, load calculation on several load cases under IEC criterion was carried out, the data of which is based on the prototype of SUT-1000 Mega-watt variable speed constant frequency wind turbine developed by Shenyang University of Technology funded by national ＂863＂ project.
