Using the FACTS controllers, such as static synchronous compensator (STATCOM), as it provides continuous reactive power, in the grid including wind turbine (WT) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. In this paper, in order to contr...

VFT (variable frequency transformer) has been recently used as an alternative to HVDC (high voltage direct current) to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster initial transient recovery, and has better natural damping capability. VFT is simply a DFIM (doubly-fed induction machine) where the machine torqu...

This paper presents the review of the Doubly fed Induction Generator (DFIG) based Wind Energy Conversion System (WECS). Basically the various challenges of the grid connected DFIG based wind turbine has been highlighted in this review. Nonlinear model of wind turbine with DFIG configuration are explained and a 1.2 MW, 50 Hz, 6 pole DFIG simulated using MATLAB/SIMULINK. Some important control is...

This thesis deals with the modeling, analysis and control of a novel brushless generator for wind power application. The generator is named as rotating power electronic brushless doubly-fed induction machine/generator (RPEBDFIM/G). A great advantage of the RPE-BDFIG is that the slip power recovery is realized in a brushless manner. This is achieved by introducing an additional machine termed as...

The rotor configuration of the brushless doubly fed induction generator (BDFIG) plays an important role in its performance. In order to make the magnetomotive force (MMF) space vector in one set rotor windings to couple both magnetic fields with different pole-pair and have low resistance and inductance, this paper presents a novel wound rotor type for BDFIG with low space harmonic contents. In...
