Abstract: When a short circuit fault occurs in the grid side connected the DFIG, the LVRT ability of DFIG based on the traditional crowbar technology is poor, and the DFIG need to absorb a mass of reactive power from the grid. Therefore, the terminal voltage is difficult to be recovered. In reaction to this technical disadvantage, an improved integrated control strategy is proposed. Firstly, through using DC-chopper in the basis of the crowbar technology, the DC bus overvoltage and the overcurrent of the rotor side can be limited during the fault stage. Secondly, a differential compensation term control of stator exciting current is introduced to the rotor side to enhance the mechanical stress of the system unit shaft. When a serious fault occurs in the grid, the improved GSC control strategy can be switched from normal operation mode to supporting mode of the reactive power, which compensates to the needed reactive power of the system and provides a part of reactive power to grid. A simulation model of grid-connected DFIG is built in the PSCAD/EMTDC platform. The experimental results show that, in different voltage dip, the proposed control strategy can improve the capability of low voltage ride through of DFIG.
