    Abstract: In allusion to the hard problem of double-fed induction generator (DFIG) low voltage ride through(LVRT), combining with the current situation of the development at home and abroad, this paper analyzed the impact of grid voltage drop on DFIG, pointing out several kinds of solutions on the influence of this question. Combining with the current development orientation of wind power at home and abroad, this paper gave two more comprehensive meaning solutions. One is to use the flexible direct current interconnection, and the other is to add the dynamic voltage compensator based on super capacitors.
    Key words: double-fed Induction generator; low voltage ride through; flexible direct current; dynamic voltage compensator
