In this paper, a dynamic modeling and power control scheme for doubly-fed induction generator (DFIG) for variable speed wind power generation is proposed. A detail dynamic model of a DFIG-based, wind turbine and grid-connected system is presented in the _d_–_q_-synchronous reference frame. A robust controller based on sliding mode controller (SMC) is applied in order to control the power flowing ... إقراء المزيد

Negative impacts of the grid faults in the Doubly Fed Induction Generators (DFIGs) based wind turbines systems include the stator and rotor over currents, DC-link over voltage, electromagnetic torque oscillations, active and reactive power fluctuations at the grid connection point, potentially leading to destabilization of the power system network. For eliminating of the negative impacts, thus enhances the DFIGs based ... إقراء المزيد
