Fault detection in squirrel cage induction machines based on stator current spectrum has been widely investi­ gated. Several high resolution spectral estimation techniques have been developed and used to detect induction machine abnormal operating conditions. In this paper, a modified version of MUSIC algorithm has been developed based on the faults(More)
—Development of large scale offshore wind and marine current turbine farms implies to minimize and predict maintenance operations. In director indirect-drive, fixed-or variable-speed turbine generators, advanced signal processing tools are required to detect and diagnose the generator faults from vibration, acoustic, or generator current signals.

Cette étude traite de l'estimation de la fréquence fondamentale dans les réseaux électriques. Nous proposons trois estimateurs de la fréquence fondamentale exploitant conjointement la structure harmonique et la nature multidimensionnelle du signal. Les résultats de simulation montrent que ces techniques permettent d'obtenir une estimation précise de la(More)
