Abstract In this paper, the second-order differential equation of double-fed induction generator (DFIG) in complex field is established based on the fifth-order model of the DFIG, considering the stator and the rotor transients as well as the Thevenin equivalent circuit of the external system. Then, the approximate analytical solutions to the free responses of the flux and current and the corresponding approximate time constants formula are obtained. Furthermore, the verification approach for the proposed approximation is suggested, and the verification simulations are carried out. Moreover, the impacts of faults position and faults resistance on the time scales of the free responses are analyzed by simulations. The results show that the fault characteristics have great impacts on the time scale of the stator and rotor transients of DFIG. Therefore, the transient analyses with different faults require different models. Finally, the adaptability of the electromechanical transient model with or without the stator or rotor transient in the electromechanical transient analysis is discussed.
