N2 - This paper proposes a DC-link voltage control method for the permanent magnet synchronous generator (PMSG) wind power system with a full-rated back-to-back converter, to improve the dc-link voltage dynamic response under normal operation and grid faults conditions. The dc-link voltage is controlled by the motor-side converter, while the grid-side converter is responsible for the maximum power point tracking. Considering the system nonlinear characteristic, a dc-link voltage controller is designed based on the feedback linearization theory. With this control scheme, the dc-link voltage responses much faster than other control structures. It can suppress the dc-link voltage fluctuation with the wind speed varying and prevent the voltage from rising too high under grid faults. The validity of the control algorithm has been verified by simulation with Matlab/Simulink, and the results show a better dc-link dynamic response with the proposed control scheme.
