摘要：
The dynamic coupling between the doubly fed induction generator (DFIG) and the power grid is strengthened during the severe asymmetric fault of weak grid, which makes the wind power system have the risk of oscillation instability. To explore the oscillation instability mechanism, the complex frequency domain impedance model considering the controller dynamic was derived. Based on the input-output characteristics of impedance model, the dynamic interaction between the positive and negative sequence impedances of the DFIG-based wind turbine and power grid was described. Moreover, the influence of different factors on the dynamic stability of system during weak grid asymmetric fault was investigated by the generalized Nyquist criterion. The suggestions of controller bandwidth selection during fault were proposed. Finally, the correctness of theoretical analysis was verified by the simulation and experiments. © 2021 Chin.
