| Abstract: | In order to improve the stability of power system,the capability of fault ride-through(FRT) is required for the large wind farms.The research on fault ride-through of doubly-fed induction generator(DFIG) has become a hot issue.The standards of fault ride-through are introduced,and then the transient characteristics of doubly-fed induction generator and the working principle of brake resistance are analyzed.The effects of brake resistance placed at the low side of the transformer of wind farm or the terminal... |
