Surplus of reactive power at recovery progress after grid voltage dips, suddenly removed load and resonance over-voltage because of single phase to earth fault in the neural indirectly grounded power systems will cause grid surge. For the stator of doubly-fed wind power generator connected to grid, the transient process of grid surging will cause the stator voltage and current shock and motor torque oscillate. DC chopper circuit is added and pulse-management-control logic is formulated to achieve the protection of converter to ride through grid voltage soared period. The grid reactive power priority strategy is proposed in order to output maximum voltage. Besides, virtual rotor damping control is used on converter to speed up DC magnetic relaxation, avoid DC Chopper frequently operation and alleviate oscillation of the motor torque. Model of main electricity circuit is established by Simulink and program is embedded in Simulink as a controller module in the hybrid simulation in order to be close to the actual circumstances. According to the simulation results, the validity and feasibility of strategy and protection scheme are proved. Besides, the accuracy of the program code is confirmed.
