Abstract：Recently, with the rapid increase of wind power generation, the trip off of wind farm will have an increasing impact on power system .In this paper, the fault ride through grid codes of wind farm is introduced at first, then a third-order phase model is used for superconducting magnetic energy storage (SMES). The integrated control system of DFIG is divided into wind generator control system, rotor side and the stator side converter control system. SMES unit is used to improve fault ride through capability and dynamic response of DFIG. At last, the simulation model of SMES+DFIG are built in Matlab/Simulink, high voltage ride through（HVRT）grid code of the United States and low voltage ride through（LVRT）grid code of China are used to verify the ability of the SMES unit to avoid wind turbine generator from being disconnected from the grid.
