Induction generator based on doubly-fed machine
2018 17th International Ural Conference on AC Electric Drives (ACED), 2018The authors analyzed the approach to implement a self-contained generator based on an induction motor with a wound rotor with connection of a stator circuit to the load and with the power supply of rotor windings from a regulated source of alternating current.

Control of the doubly Fed Induction Generator in WECS
The 2nd IEEE Conference on Power Engineering and Renewable Energy (ICPERE) 2014, 2014The major part of the existing research works concerning variable speed wind turbines control is not only to capture the maximum power from the wind but, also, to improve the quality of power and to converge the system for operating at unity power factor. This paper proposes a new power control of a variable speed wind energy conversion system based on

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.

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.

Power control for a doubly fed induction generator
2012 IEEE International Conference on Complex Systems (ICCS), 2012This paper proposes a direct power control scheme of a doubly-fed induction generator under wind speed variations. The PI controllers are used to control active and reactive power. A control scheme is developed that uses stator flux orientated vector control.

Virtual torque control in wind generation with doubly fed induction generator
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012In this work, a controller design strategy for wind turbines with doubly fed induction generators is addressed. The goal of the controller is to assure bounded both power derivative and blade pitch angle derivative, at the same time that the accelerations of the machine are minimized in order to avoid harmful fatigue loads.

Control of Doubly-Fed Induction Generator System Using PIDNNs
2010 Ninth International Conference on Machine Learning and Applications, 2010An intelligent control stand-alone doubly-fed induction generator (DFIG) system using proportional-integral-derivative neural network (PIDNN) is proposed in this study. This system can be applied as a stand-alone power supply system or as the emergency power system when the electricity grid fails for all sub-synchronous, synchronous and super ...

Modeling and control of the doubly fed induction generator wind turbine
Simulation Modelling Practice and Theory, 2010The present paper deals with the modeling of wind turbine generation systems. The model of a doubly fed induction generator, along with the corresponding converter, crow bar protection and electrical grid is described. The different level control strategies both in normal operation and under voltage dig conditions are discussed, including speed control,

Power and Speed Control of Brushless Doubly-Fed Induction Generators [PDF]
The brushless doubly fed induction generator (BDFIG) with a partially rated converter has characteristics of a squirrel cage induction generator and a conventional synchronous generator. Its control is challenging due to the machine's complicated structure, which requires an effective controller to stabilize it within its normal speed range and under ...
