Abstract |
The doubly-fed induction generator (DFIG) is a variable speed induction machine and is widely used as modern large wind turbine generators. It is a wound rotor induction machine with its stator windings directly connected to the grid and its rotor windings connected to the grid through an AC/DC/AC PWM converter. This paper describes the modeling aspects of doubly-fed induction generator during steady state and faulty conditions. Vector decoupling controls strategy has been adopted to establish the mathematical model of DFIG based wind generator. In this paper, 1.5 MW DFIG is modeled in MATLAB/Simulink and, voltage and current waveforms are presented and discussed for symmetrical and unsymmetrical faults located at various locations of grid connected wind power system in Myanmar. Keywords: Doubly-fed induction generator, Faulty conditions, Mathematical model, Vector control. | |||||||||
