With great development of wind power in recent years, it is a trend that doubly-fed induction generators (DFIGs) and permanent magnet synchronous generators (PMSGs) operate together in one wind farm. Because of the differences between transient characteristics of the DFIG and PMSG, the short-circuit current of DFIG could be affected by the PMSG. The short-circuit current of whole hybrid wind farm can not be calculated accurately. In this paper, fundamental-frequency fault model of hybrid wind farm consisting of DFIGs and PMSGs is built. The short-circuit current of the DFIG considering the influence of multiple different wind turbines is deduced. Based on the comparison with short-circuit current of single DFIG, factors and change law of short-circuit currents of DFIG in hybrid wind farm are analyzed and summarized. Short-circuit currents of DFIG under different conditions are analyzed and verified by time domain simulations.
