摘　　要：通过分析风力发电机组中传动系统的特性,针对不同类型的风力发电机组提出了灵活的传动系统建模方法(包括4种模型:刚性轴感应发电机模型、柔性轴感应发电机模型、刚性轴变速发电机模型和柔性轴变速发电机模型),并采用数字模拟方法在软件中加以实现,与商业风力机计算分析软件GH-Bladed中的风力发电系统运行结果进行对比,验证了模型的准确性,运行结果表明,该文提出的建模方法能够满足不同传动系统的惯性要求,并且能方便的在软件中根据实际风力机参数进行模型选择和参数设置,为实验室模拟风力发电系统提供了理论依据和模拟方法。In this paper, transmission system performance has been analyzed, flexible modeling methods have been present according to different wind power systems, including rigid shaft-induction generator model, flexible shaft-induction generator model, rigid shaft-variable generator ：model, flexible shaft-variable generator model. Based on those models, software has been designed to show the performance of the transmission system, and then contrast with the result that simulated by GH_ Bladed software, to test and verify the accuracy of the models. Results have shown that the models presented can meet different transmission system requirement, users can set parameters easily based on the actual wind turbine. The theoretical basis and modeling method have been provided for wind power simulation in laboratory.
