The large-scale penetration of wind power may cause serious wide-band oscillations. Wide-band oscillation is closely related to the capacity of the wind farm, the interface impedance, and the operating conditions of wind turbines generators (WTGs). In this paper, the impedance model method is adopted to analyze the wide-band oscillatory characteristics of the wind power system, so as to clarify the relationship between the penetration capacity of the wind farm and the grid impedance under the constraint of wide-band oscillation. Firstly, the full-operating-condition impedance model (FOCIM) of the WTG is established, which takes the voltage and output current at the terminal as variables. Then, on the basis of the FOCIM, the effects of output power and short-circuit ratio (SCR) on the wide-band oscillation are analyzed. Furthermore, how the practicable maximum capacity of the wind farm varies with the grid impedance is studied, which is of reference value for the construction and operation of the wind farm. Finally, the accuracy of the analysis results of the FOCIM is verified by time-domain simulations. The results show that the practicable maximum capacity of the wind farm considering the constraint of wide-band oscillation can be determined on the basis of the FOCIM under different grid conditions.
