Power Transfer Matrix Model and SVPWM Technique Based Multi Variable Control Method for DFIG Wind Energy System

Abstract

This paper gives an overview of Modeling and simulation of Doubly Fed Induction generator (DFIG) coupled with wind turbine using SVPWM technique. The power transfer matrix model uses instantaneous real/reactive power theory to improve the stability of power, which is injected by the wind energy to the power system. A power/current limiting scheme is also presented to protect power converters during a fault.  Because of the advantages of the DFIG over other generators it is being used for most of the wind applications. Various researches have been done in modeling and simulation field of DFIG coupled with wind turbine. This paper summarizes the researches in the area of study of DFIG, steady state and transient analysis, its modeling, simulation, reactive power control strategies and performance analysis of DFIG coupled with wind turbine. The control schemes of DFIG are modelled and simulated in MATLAB/SIMULINK.
