Electromagnetic transient model of doubly fed induction generator(DFIG) during symmetrical short-circuit fault occurred in power system connected with DFIG and fault transient process of magnetic linkage in the stator and the rotor of DFIG are analyzed,and then the expression of short-circuit current in stator of DFIG under different stator voltage drop extents is derived and a method to correct the stator voltage drop coefficient,by which the calculation error of short-circuit current can be effectively re...
