Abstract

Abstract: Brushless doubly-fed induction generator has good system reliability due to the cancellation of the brush and slip ringcompared with DFIG.The low voltage ride-through (LVRT) capability is the key to realize the uninterrupted operation for the wind power generation.In this paper, the LVRT issuefor different grid faults is studied. The dynamic responses of the change of power winding magnetic linkage and the change of control winding voltage are analyzed when grid fault occurswith symmetrical fault and unsymmetrical fault respectively based on mathematical model of BDFIG. Theinstantaneous voltages of control winding are calculated and the dynamic responsesare simulated under different grid faults. The study work in this paper provides a theoretical basis for designing circuit parameters and control strategy for LVRT protection.
