Dynamic Modelling Of Doubly Fed Induction Generator Based Wind Turbine System
The dynamic model of doubly fed induction generator (DFIG) wind turbine including models for both mechanical
components as well as for all electrical components. It is also consisting of controllers and protective device for this model
during grid faults. The main aim of this paper is to modelling of a variable speed wind turbine with doubly-fed induction
generator (DFIG). They are widely used in wind energy generation systems. Here, the rotor is considered fed by a voltage
source converter (VSC) whereas the stator is connected to the grid directly. A mathematical model of the machine is written
in appropriate d-q reference frame that is established to investigate simulations. The capacity of the wind power generation is
2MW. The voltage rating and frequency for this system are 690V, 50Hz. The location of wind turbine is selected at near the
Sitaway Area, Rakhaing State (range from 4 to 8 m/s) which is one of the possible wind power generation sites in Myanmar.
This paper describes modelling, simulation, reactive power control strategies and performance analysis of DFIG coupled with
