This paper presents the analysis and operation of doubly fed induction generator (DFIG)-based wind power generation system under unbalanced network voltage conditions. The limited voltage and current ratings, the control capabilities of both the grid-side and the rotor-side converter (GSC & RSC) for unbalanced network voltage compensation are investigated in detail. A new current control scheme,...
The variable speed constant frequency (VSCF) wind power generation system requires the DFIG with characteristics of high response speed as well as strong robustness. Under the mutual effects of internal interference of parametric variation and external interference of load torque oscillation, the dynamic current response of PI control becomes worse, as well as reduced efficiency and stability. Aiming...
