Abstract:In this paper, we present a new strategy of control DFIG-generators for wind turbines' variable-speed connected to grid. The main objective is the management of voltage drop and flicker and the generation of voltages and a fixed frequency to the grid. This strategy is based on adaptive backstepping control and crowbar reduces the duration of voltage drops. The results obtained during the validation of this model show a great improvement and robustness of system performance and the quality of the injected voltage electrical grid.
