A Dynamic LVRT Solution for Doubly Fed Induction Generators

IEEE Transactions on Power Electronics, 2009
Doubly 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, 2010
In 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 ...

Intelligent control of a brushless doubly-fed induction generator

International Journal of System Assurance Engineering and Management, 2019
Brushless doubly-fed induction generator (BDFIG) has drawn significant attention in recent years in variable speed drive applications due to such features as simple and robust construction, favorable operating characteristics and reduced maintenance. The objective of BDFIG control is to achieve better performance compared to the doubly fed induction ...

Additive and multiplicative fault diagnosis for a doubly-fed induction generator

2011 IEEE International Conference on Control Applications (CCA), 2011
The problem of additive and multiplicative fault detection and isolation (FDI) in the current sensors of a doubly-fed induction generator (DFIG) is considered in the presence of model uncertainty. A residual generator based on the DFIG model is proposed using the structure of the classical generalized observer scheme (GOS).

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 ...

The algebra of the ideal doubly-fed induction generator

2016 IEEE/ACES International Conference on Wireless Information Technology and Systems (ICWITS) and Applied Computational Electromagnetics (ACES), 2016
Three-phase, doubly-fed induction generators (DFIGs) are key constituents of power conversion plants. Modeling and control of a DFIG become relevant to deal with intermittency in primary energy supply (e.g., the wind velocity field) and with uncertainty in the load.

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.

Determination of parameters of doubly-fed induction generators

2016 XXII International Conference on Electrical Machines (ICEM), 2016
In 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), 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.
