摘要

The brushless doubly fed induction generator has been proposed for use in wind turbines as a more reliable alternative to the more commonly used doubly fed induction generator. To realize the commercial promises of the brushless doubly fed induction generator in this role, it must meet the existing grid connection codes, particularly with respect to low-voltage ride-through. In this article, the application of series dynamic resistors is proposed to enhance brushless doubly fed induction generator low-voltage ride-through capability, and the required analysis is provided. Three locations for series dynamic resistors are suggested in the brushless doubly fed induction generator circuit and are compared to each other from various points of view, e.g., their impact on current peaks and reactive power generation. Furthermore, modal analysis is performed to check the impact of series dynamic resistors on the damping of power winding and control winding dynamics. The validity of the analysis and the effectiveness of the proposed approach are confirmed via time-domain simulations.
