The aim of this paper is to present the modeling and simulation of a doubly-fed
induction generator driven wind turbine using Simulink modeling. Here there are
two pulse width modulation based voltage source converters were connected back
to back to the utility grid via a common dc link between the rotor terminals.
The reactive power in the grid side converter itself is compensated rather than
providing an additional compensating device and from the rotor side all
remaining power is also extracted. To supply the required reactive power to a DFIG,
the rotor side converter is used to attain maximum power extraction. The
dc-link voltage is controlled by the grid-side converter which makes the
reactive power drawn from the utility to zero and ensures the operation by
using the stator voltage-oriented control technique in system controls. The
performance of DFIG wind system during various fault conditions and during
dynamic loading are analyzed for variable wind speeds. All these methodologies
were simulated with the help of components in simulation software program using
MATLAB provided in SIMULINK library.
