  ABSTRACT: Analyzing the wind turbine with a direct-driven PMSG, this paper proposes a low voltage ride through scheme of PMSG wind power systems based on feedback linearization. The DC-Link voltage is controlled by the generator-side converter rather than the grid-side converter. Considering the nonlinear relationship between the DC-Link voltage and the generator rotor speed, the controller of DC-Link voltage uses a feedback linearization technology. The grid-side converter which controls the grid active power according to the maximum power point tracking adds a judgment link for the generator speed reference. The model of 2 MW PMSG wind power system was simulated by using PSCAD. The simulation result has verified the validity of the proposed control scheme.
