摘　　要：综合考虑风轮非定常气动载荷计算模型、传动系统动力学模型、双馈发电机模型和变速变桨距控制模型,建立风力发电机传动系统在不同工况下的动态外载荷计算模型。使用所建立的计算模型对变速变桨距型风力发电机分别在启动、运行和制动时的外载荷进行计算分析,得到增速齿轮箱的输入载荷变化规律及其影响因素。The loads of the drive-train of the variable speed variable pitch wind turbines in different operation conditions were studied in this paper. Combined the unsteady aerodynamic model, drive-train dynamic model, doubly fed induction generator （DFIG）model and the variable speed and pitch control models, the dynamic loads calculation model of the wind turbines drive-train was established. By using the loads calculation model, the loads of a 1.5 MW variable speed variable pitch wind turbine respectively at startup, normal running and braking stages were calculated. From the calculation results, the variation regulations and its effect factors of the gear transmission system＇ s input loads were obtained.
