A reverse current tracking based LVRT strategy for doubly fed induction generator (DFIG)
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013This paper proposed an improved control strategy for doubly fed induction generator (DFIG) to enhance its low voltage ride-through (LVRT) capability. Under serious grid faults, the rotor side induced electromotive force (EMF) would exceed the maximum output voltage of the rotor side converter (RSC), leading to over-currents and runaway of DFIG and RSC.

Decoupled active and reactive power control of a Doubly-Fed Induction Generator (DFIG)
2007 Mediterranean Conference on Control & Automation, 2007In this paper a decoupled control of a doubly-fed induction machine used in generation mode (DFIG) is presented. It provides decoupled regulation of the primary side active and reactive power and it is suitable for both electric energy generation and drive applications. The mathematical model of the machine written in an appropriate d-q reference frame

A novel linear controller for grid connected doubly fed induction generator (DFIG)
2012 International Conference on Advances in Power Conversion and Energy Technologies (APCET), 2012The advent of rising electrical energy consumption gave rise to a steady increase in the demand on power generation. So, in addition to conventional power generation units a number of renewable energy units are increasingly being integrated into the system.

An Improved Technique of Wind Power Harvesting With a Doubly Fed Induction Generator (DFIG)
2018 IEEE 8th Power India International Conference (PIICON), 2018The paper presents that the improved green power harvesting technique is proposed by the variable speed conditions of the doubly fed induction generator (DFIG) at the site of the wind farms. The DFIG system plays an important elucidation to meet up the power demand for the grid mode of the operations as a unique technique of the robust energy ...

Power System Oscillation Damping Capability of Doubly Fed Induction Generator (DFIG)
2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D), 2018The increasing amount of wind power generation essentially replaces the conventional synchronous generators of the power system, thereby, reducing the total inertia of the system. Reduced inertia of the system is expected to hamper the system response during contingencies.

Modeling and Control of Doubly Fed Induction Generators (DFIGs) For Wind Energy Applications
2006 International Conference on Industrial and Information Systems, 2006Various literatures have been published on the application of doubly fed induction generators for wind power generation. The wind turbines and the induction machines have their own inherent characteristics and literature on how the wound rotor induction generator behaves when coupled to the wind turbine together with its control, is limited.

In this paper, a reduced order state observer for DFIG is designed that estimate the states with just using DFIG's stator voltage and power measurements. Further, the proposed state observer is used to provide two control strategies for Rotor Side Converter (RSC) of DFIG a) state estimator based state feedback control and b) state estimator based ...
