BEHAVIOUR ANALYSIS OF DOUBLY FED INDUCTION GENERATOR BASED WIND TURBINE SYSTEM DURIN GRID DISTURBANCES

Abstract

The fault response of doubly fed induction generator (DFIG) based wind turbine is analyzed and summarized with vector control scheme to show the influence on the dynamic behavior of the wind turbine system against this operation condition as fault ride through (FRT) enhancement. The theoretical fault simulations for voltage sag magnitude calculation are included utilizing Simulink, based on the SimPowerSystems toolbox, and also considering protection-systems modeling for sag duration calculation.
