This paper deals with the study of the performance of a wind energy conversion system (WECS) based on a doubly fed induction generator (DFIG) under the IGBT open-circuit fault of the rotor side converter (RSC) during the application of robust control techniques, such as backstepping control (BSC) and sliding mode control (SMC). The presence of IGBT open-circuit faults in DFIG-WECS can disrupt service...
Spectral analysis of stator current allows us to study and identify the saturation harmonics for the case of a healthy motor and a motor with an eccentricity fault This paper describes the influence of magnetic saturation on the diagnosis of mixed eccentricity fault in squirrel induction motors by a modeling and a simulating work. The effect of eccentricity and saturation are included in the calculation...
