Application of Superconductors to Suppress Ferroresonance Overvoltage in DFIG-WECS

IEEE transactions on energy conversion, 2022
While much attention was given in the literature to improve the fault ride through (FRT) capability of a doubly-fed induction generator (DFIG)-based wind energy conversion system (WECS) during various faults at the grid side, not much attention was given

Nonlinear Decoupling Control of DFIG

Advanced Materials Research, 2013
DFIG (Double Fed Induction Generator) becomes a competitive wind power form due to it needs small capacity converter and the controllable of system efficiency and power factor. Aiming at back to back three-phase voltage-type PWM converter of the doubly-fed VSCF wind turbine, the nonlinear mathematical model of the controller of rotor side and network ...

Improved Continuous Fault Ride Through Control Strategy of DFIG-Based Wind Turbine During Commutation Failure in the LCC-HVDC Transmission System

IEEE transactions on power electronics, 2021
The commutation failure fault usually occurs in the line-commutated-converter-based high-voltage direct current transmission system. When commutation failure fault occurs, the voltage of sending alternate current (ac) system changes rapidly, and the ...

Passivity based control of a DFIG wind turbine

2006 American Control Conference, 2006
A novel passivity based control for the electric generator of a wind turbine is presented. Operating points are prescribed to this controller, to maximize generated electric power. The controller is designed using the non-linear model of the electric generator and it is guaranteed to have tracking properties for the electric and mechanical references ...

New Protection Scheme of DFIGs

2020
This chapter proposes a control strategy of doubly fed induction generators (DFIGs) with new protection schemes for enhancing fault ride through capability of wind farms composed of DFIGs and induction generators (IGs). Since the DFIGs will be stressed or overloaded in the process of stabilizing the wind farm during a grid fault, it is paramount to ...
