Dynamic Behavior of DFIG Wind Energy Conversion System under Various Faults

N.Dhayanidhi, D.Muralidharan

The dynamic behavior of a DFIG grid connected, wind energy conversion system (WECS) is simulated using MATLAB. This paper presents the different fault conditions like line to ground faults, double line to ground faults and three phase faults. A fuzzy controller is integrated into the doubly fed Induction Generator (DFIG) Wind Energy Conversion System. The dynamic behavior for a DFIG Wind Energy Conversion system with fuzzy controller is simulated for different fault conditions and the results are compared to that of the system with PI Controllers. The comparison shows that the integrated fuzzy controller results in an improvement in the dynamic behavior of the system under transient conditions
