Based on the analysis of electromagnetic transient response， a test scheme to simulate the grid voltage dip and recovery by the stator asynchronous grid-connection is presented. The stator grid-connection is implemented under the condition that the magnitude error between the stator and grid voltage which is controlled by the rotor magnetizing current. The transient behavior of the stator-flux， stator and rotor currents， and DC-link voltage are analyzed. It indicates that the proposed test scheme can simulate the grid voltage dip and recovery. And the control performance of the rotor side converter is tested. Simulation and experimental results validate the feasibility of this test scheme.
