本文系统讨论了用于电力系统暂态稳定评估的双馈感应发电机（DFIG），并详细研究了大型双馈风电场并网对电力系统暂态稳定的影响。在 DFIG 建模中，采用等效发电机模型来反映 DFIG 及其转子变流器的组合行为。此外，还考虑了转子侧变流器的控制策略，即定子有功功率和无功功率的解耦控制。进行了相应的数值模拟，探索和利用同步发电机和风电场分别对电力系统暂态稳定的影响和相互作用。特别是，在仿真比较过程中考虑了不同的同步发电机动态模型和负载模型。最后，本文给出了一些有意义的结论和评论。
In this paper, the Doubly-fed Induction Generator (DFIG) for transient stability evaluations of power systems was systematically discussed, and the impacts of grid-connected large DFIG based wind farms on power system transient stability were then studied in detail. In the modeling of DFIG, an equivalent generator model was employed to reflect the combined behavior of the DFIG and its rotor converter. Furthermore, the control strategy of rotor-side converter, which was for the decoupled controls of the stator active and reactive power, was considered. The corresponding numerical simulations were carried out to explore and exploit the influences and interactions between synchronous generators and wind farm respectively on power system transient stability. In particular, different synchronous generator dynamic models and load models are considered during the simulation comparisons. Finally, some meaningful conclusions and comments are given in this paper.
