Fault Analysis and Simulation of a Grid Connected Doubly Fed Induction Generator for Wind Energy Conversion System

Abstract

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.
