Conventional studies on the high voltage ride through problem of doubly fed induction generator（DFIG）usually focus on the transient characteristics during voltage swell faults and ignore dynamic changing of stator flux linkage after fault recovery. We studied the electromagnetic transient whole-process at grid voltage asymmetric swell and fault removal. To analyze the complexity of phase sequence separation for traditional de-excitation control

a reverse current tracking control strategy without flux linkage and system parameters is proposed. The simulation results verify the correctness of the theoretical analysis. The proposed control strategy accelerates the decay rate of the transient flux and suppresses the pulsation of the electromagnetic torque.
