Doubly-Fed Induction Generators for wind power generation

2007 International Conference on Industrial and Information Systems, 2007
There are many papers available on doubly fed induction generator (DFIG) and their control. However, there are gray areas where a laymen into the wind industry cannot fully understand with regard to the operation of these machines. This paper presents from first principles, the operation and control of the DFIG, and supplement the theory by results ...

Efficient Solar Integrated Doubly Fed Induction Generator for Wind Energy Harnessing

, 2020
Doubly-Fed Induction Generator (DFIG) is a dual input conventional asynchronous device connected across both stator and rotor, which also functions as an electrical transducer consuming up-to 30 % of the generated power during the rotor injection ...

Harmonic analysis of doubly fed induction generators

The Fifth International Conference on Power Electronics and Drive Systems, 2003. PEDS 2003., 2004
This paper gives an overview of the frequency spectrum of the stator and rotor currents in a doubly fed induction generator (DFIG) used in wind power applications. The paper also presents a method to eliminate higher harmonics and interharmonics in the DFIG stator current.

Doubly Fed Induction Generators

2010
Adjustable speed induction generators, especially the Doubly-Fed Induction Generators (DFIG) are becoming increasingly popular due to its various advantages over fixed speed generator systems. A DFIG in a wind turbine has ability to generate maximum power with varying rotational speed, ability to control active and reactive by integration of electronic

Bearing currents in doubly-fed induction generators

2005 European Conference on Power Electronics and Applications, 2005
An increasing demand on the quality of wind power systems affects also more and more the fields of lifetime and reliability. But, problems like bearing damages because of bearing currents counteract these desired demands. Especially doubly fed induction generators, which are wide spread in use for wind turbines up to the MW-class can be limited in ...

Frequency Regulation By Doubly Fed Induction Generator

2019 IEEE International Conference on Electrical, Computer and Communication Technologies (ICECCT), 2019
Conventional 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), 2018
The 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.

Impedance modeling of doubly-fed induction generators

2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015
This 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.
