摘要：
This paper investigates the control and operation of brushless doubly-fed induction generator (BDFIG) under unbalanced network. The system topology and mathematic model of BDFIG is presented, and system behavior under unbalanced grid voltage is discussed. Dual current inner loop control of grid side converter is adopted to suppress the DC link voltage fluctuation. In order to eliminate adverse effects under unbalanced network, different control targets are presented and the current control strategy of machine side converter is proposed, which includes a main controller and an auxiliary controller. Simulation results verify the effectiveness of the control strategy in suppressing power and current oscillation of a BDFIG system under unbalanced network.
