Critical clearing time of doubly fed induction generator
2005 IEEE Russia Power Tech, 2005A detailed model of grid-connected doubly-fed induction generator (DFIG) suitable for fault analysis is presented. 5th order model of wound rotor induction machine together with a two-mass model of the mechanical drive-train is employed to investigate transient voltage stability of integrated wind turbine.

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.

Bit-Stream control of Doubly-Fed Induction Generators
2010 IEEE International Conference on Sustainable Energy Technologies (ICSET), 2010Bit-Stream based control, which uses one bit wide signals to control power electronics applications, is a new approach for controller design. A Bit-Stream based control system for the Rotor Side Converter (RSC) of a Doubly Fed Induction Generator (DFIG) is proposed to demonstrate that the Bit-Stream control technique is suitable for complex vector ...

Intelligent adaptive control of doubly fed induction generator
2010 IEEE International Conference on Power and Energy, 2010Induction generators have gained an important rule in many applications. These generators have a very wide rotor speed operation range and reactive power with non-linear characteristics. As a result the linear controllers which have been designed for an operating point don't show a properly function for controlling the generator outputs.
