This paper studies the impacts of grid voltage swell on the dc-link voltage for doubly fed induction generator (DFIG). A flexible algorithm of the dc-link voltage is proposed to meet the requirements of wide variation in grid voltage. The dc-link voltage reference is regulated with the variation of grid voltage. Thus, the dc-link voltage is maintained to a constant during normal operation but a relatively high value during grid voltage swell. The power losses are evaluated with the conventional… CONTINUE READING
