Investigation of the operational behaviour of a wind energy conversion system including double fed induction generator in converter's faulty conditions

In this paper, the wind energy conversion system that uses the structure of Doubly-Fed Induction Generator (DFIG) under fault condition is presented. Moreover, a simulation of this wind energy conversion system under fault conditions in MATLAB/SIMULINK is done and the results are evaluated. Two typical cases of fault, open-circuit faults in two IGBTs in Rotor Side Converter and in one diode in Grid Side Converter are studied.
