Comparison between two algorithms of Control of DFIG for power system fault ride through

This paper presents the comparison of two different algorithms for control of a doubly fed induction generator(DFIG) in wind energy conversion systems(WECS).both Two control algorithms are based on VC method.This algorithms called in this paper: 1) Series compensation algorithm and 2) Acceleration of rotor algorithm. In thispaper two algorithms reviewed and their performances analyzed and compared on the basis of simulation on Matlab/Simulink. . Both two proposed algorithms is better than without compensation. The series algorithm is better maintain the voltage of stator and inject reactive power to grid. The advantage of acceleration algorithm is that fault energy is stored in kinetic energy
