Determination of parameters of doubly-fed induction generators
2016 XXII International Conference on Electrical Machines (ICEM), 2016In this paper, the identification of equivalent circuit parameters of a doubly-fed induction generator (DFIG) is investigated. To date, several methods have been presented to identify or estimate induction machine (IM) parameters by using IEEE Std. 112. However, for accurate results using this standard, adjustments according to the machine's design are

Frequency Regulation By Doubly Fed Induction Generator
2019 IEEE International Conference on Electrical, Computer and Communication Technologies (ICECCT), 2019Conventional generators which provide frequency regulation in power systems are getting replaced by renewable sources. So in a system which is penetrated by Wind Energy Conversion System (WECS), we need to think of providing frequency regulation features in the WECS itself.

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 ...
