Performance Analysis of Doubly-Fed Induction Generator Based Wind Power System

Doubly Fed Induction Generator (DFIG) is the most popular variable speed wind energy conversion system (WECS). In this proposed work the performance of wind energy system based on Doubly-Fed Induction Generator (DFIG) is analyzed in grid tied mode by studying the different techniques such as grid integration, droop phenomenon, and power control. The results are obtained using the MATLAB/SIMULINK environment. It has several benefits such as better efficiency, rating of the converters is less because the power semiconductor units are connected with the rotor circuit; cost efficient, loss of those is minimum, easy power factor correction, possibility of four quadrant active and better utilization factor.
