一般风场中通常会含有不同参数、不同型号甚至不同结构的风电机组，为将此风场较为准确地表示出来，提出了通用化建模的思路，即将风电场的风机用一个通用化的模型表示出来，以模拟不同风机的特性。根据此思路，具体研究了风力发电系统中的关键机构传动系统的通用化建模，对此通用化模型在双馈风机以及直驱风机上进行了暂态仿真，给出了可以忽略和应予以保留的参数。为保证模型的准确性，采用多组不同的参数对模型进行测试，分析了不同参数对系统的影响，以此验证通用模型的有效性，并进一步说明所提出的通用化建模思路的可行性，从而为风力发电系统建模提供参考。

In general there are different types of wind turbine generation units with different parameters and structures in a wind farm. To represent such a wind farm more accurately, a thinking of generalized modeling is proposed, namely, the wind turbines in a wind farm are represented by a general model to simulate the characteristics of different types of wind turbines. According to this thinking, the generalized modeling of the key mechanism, i.e., the drive-train system of wind power generation system, is researched concretely. The simulations of such a general model with doubly fed induction generator (DFIG) and direct-driven wind turbine generator under transient condition are performed respectively, and based on simulation results two kinds of parameters, one of them is ignored and another of them is to be retained, are given. To ensure the accuracy of the proposed general model, multi groups of different parameters are utilized for the tests of the general model, and the impacts of different parameters on drive-train system are analyzed to validate the effectiveness of the general model, and feasibility of the proposed thinking of generalized modeling is further explained.
