摘要：For grid-connected DFIG-based wind turbine, Fault Ride Through (FRT) or Low Voltage Ride Through (LVRT) capability is vital problem that need to be improved. This paper proposes an Active Disturbance Rejection Control (ADRC) strategy applied to Doubly Fed Induction Generator (DFIG) based Wind turbine (WT), which integrates a Dynamic Voltage Restorer (DVR). The DVR connect in series the DFIG output terminal and the utility grid. The ADRC scheme of the new topology DFIG-based WT with integrated DVR is designed to compensate grid voltage disturbances, which in turn meet LVRT requirement and increase the level of wind power penetration. The performance of this WT-DFIG-DVR structure is investigated in different operating scenarios in order to show the skills of the designed controllers.
