Online model-based stator-fault detection and identification in induction motors / De Angelo, Cristian H. in IEEE transactions on industrial electronics, Vol. 56 N° 11 (Novembre 2009)

Tubes à rayons X Résumé : In this paper, a model-based strategy for stator-interturn short-circuit detection on induction motors is presented. The proposed strategy is based on the generation of a vector of specific residual using a state observer. The vectorial residual is generated from a decomposition of the current estimation error. This allows for a fast detection of incipient faults, independently of the phase in which the fault occurs. Since the observer includes an adaptive scheme for rotor-speed estimation, the proposed scheme can be implemented for online monitoring, by measuring only stator voltages and currents. It is shown that the proposed strategy presents very low sensitivity to load variations and power-supply perturbations. Experimental results are included to show the ability of the proposed strategy for detecting incipient faults, including a low number of short-circuited turns and low fault current.

Separating broken rotor bars and load oscillations on IM fault diagnosis through the instantaneous active and reactive currents / Bossio, Guillermo R. in IEEE transactions on industrial electronics, Vol. 56 N° 11 (Novembre 2009)

Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : A new method for broken rotor bars and load oscillation diagnosis on induction motors is presented. The proposed strategy is based on the decomposition of the stator currents into their instantaneous active and reactive current components. Such components allow the decoupling of the effects produced by rotor asymmetries from those produced by oscillating loads. This allows not only the proper fault detection but also a correct fault diagnosis. Simulation and experimental results, both from laboratory and industrial cases, are presented to validate the proposal.
