摘　　要：为了研究风速为扰动源时风电系统的电网动态特性,借助PSS/E自定义功能建立了风电系统的空气动力学模型,及3种不同类型的风速模型。将这些自定义模型应用于基于双馈异步风力发电机(DFIG)的变速恒频(VSCF)风力发电机系统,验证了这些模型的有效性和正确性。这些模型的建立克服了现有PSS/E软件只有线性空气动力模型和缺少风速模型的弱点,有利于研究风力发电对电力系统运行及稳定的影响。In order to study the dynamic characteristics of power grids with wind generation when the wind speed being a turbulent source,aerodynamic model and 3 kinds of the wind speed type are proposed by using the PSS/E user-defined function in this paper.The effectiveness and correctness of these models are validated and proved in their application of VSCF （variable speed constant frequency） power system based on DFIG （doubly fed induction motor）.The construction of these models overcomes the shortage of presint PSS/E,which has only linear aerodynamic models but no wind speed models,and thus is benefit to the research of the wind generation influence on the operation and stability of the power system.
