Impedance modeling of doubly-fed induction generators
2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015This work presents sequence impedance models of Type-III wind turbines based on doubly-fed induction generators (DFIG). The models take into account the effects of both stator- and rotor-side converters as well as their control, including the phase-locked loop (PLL) and current control.

A Dynamic LVRT Solution for Doubly Fed Induction Generators
IEEE Transactions on Power Electronics, 2009Doubly fed induction generators have become the most common type of wind turbine generators. However, this type of generator is susceptible to grid-side low voltage and short circuits due to existence of a power electronics converter on the rotor side.

POG modeling of a Cascaded Doubly-Fed Induction Generator
2010 IEEE International Symposium on Industrial Electronics, 2010In this paper a Cascaded Doubly-Fed Induction Generator (CDFIG) has been modeled using the Power-Oriented Graphs (POG) technique. The dynamic equations of the system have been obtained using a Lagrangian approach. The system equations have been described with respect to a rotating reference frame to clearly show the internal dynamic structure of the ...

Several research articles have been published in conventional doubly-fed induction generator for harvesting wind energy, but the research work on unconventional doublyfed induction generator carried out very less quantity. In this direction, this paper bridges this gap by comparing the three-phase doubly-fed induction generator (TPDFIG) to novel six ...

Reactive Capability Limitations of Doubly-fed Induction Generators
Electric Power Components and Systems, 2009Abstract In the new electricity grid code, reactive power generation by wind farms, which must operate similarly to other conventional power plants, is a major concern during both steady-state and fault conditions. This article presents the reactive power capability of a doubly-fed induction generator through the use of performance capability curves ...

Cascaded doubly fed induction generator using PFC rectifiers
2009 Compatability and Power Electronics, 2009Variable speed cascaded doubly fed induction generators (CDFIG) have been recently proposed to apply in renewable energy generation systems i.e. small hydropower plants, windmills, shaft generators of vessels and embedded applications. CDFIG requires lower maintenance than DFIG due the absence of slip rings and brushes.

Novel crowbar system in doubly fed induction generators
2015 IEEE Eindhoven PowerTech, 2015Nowadays, grid code requirements demand that wind energy converters (WEC) remain connected to the grid during grid faults and contribute to the voltage support, in the same way as conventional power plants. WEC which are capable of ridding through grid faults providing voltage and reactive power support are connected to the grid via electronic power ...

Harmonic analysis of a Doubly Fed Induction Generator
IEEE PES T&D 2010, 2010The aim of this paper is to develop a framework for analysis of harmonics in a Doubly Fed Induction Generator (DFIG) caused by non-sinusoidal conditions in the rotor as well as unbalance in stator. Non-sinusoidal rotor voltages are decomposed into harmonic components and their corresponding sequences are identified.
