Low voltage ride-through of DFIG and brushless DFIG: Similarities and differences
Electric Power Systems Research, 2014The brushless doubly fed induction generator (BDFIG) has been proposed as a viable alternative in wind turbines to the commonly used doubly fed induction generator (DFIG). The BDFIG retains the benefits of the DFIG, i.e. variable speed operation with a partially rated converter, but without the use of brush gear and slip rings, thereby conferring ...

Impedance modeling of DFIG-wind turbine system
2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015 The DFIG-wind turbine, can create the potential instability to the existent power grid, equivalently presenting itself as a random voltage source with its dynamic impedance, which has the implicit and varying electrical characteristics with the changeable rotor speed.

Parameter Optimization to Power Oscillation Damper (POD) Considering its Impact on the DFIG
IEEE Transactions on Power Systems, 2022The power oscillation damper (POD) in the doubly-fed induction generator (DFIG) is to damp the low- frequency oscillation (LFO) in the power systems. But the POD will introduce the LFO to the DFIG and intensify the oscillation of the latter.

Stability Analysis for DFIG-Based Wind Farm Grid-Connected System Under All Wind Speed Conditions
IEEE transactions on industry applications, 2023The stable operation capability of the doubly-fed induction generation-based wind farm grid-connected system (DFIG-WFGS) is closely related to wind speed, and the windward velocity of wind turbine unit at different locations may be discrepant due to wake

Dynamic Analysis of DFIG Fault Detection and Its Suppression Using Sliding Mode Control
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2023In this article, a fault detection method based on chaos is proposed for doubly fed induction generator (DFIG). First, the nonlinear differential equation of the DFIG is established by the stator flux-oriented vector control method, and then, the motion ...
