PLL based grid integration of wind driven three phase induction generator

Abstract

This paper aims at developing a Phase Locked Loop (PLL) based grid integration of wind driven three phase induction (3PIG) generator. The dynamic model of wind driven induction generator along necessary power converters is evolved in Matlab/Simulink. The system functionality is analyzed for different wind velocities. The synchronous reference frame PLL (dq/SRF PLL) synchronizes the grid and the system. The PLL response for various grid conditions are analyzed and the simulation results are presented.
