Résumé:
The aim of this work to present contributions to the study of parameters estimation
and incipient fault detection winding stator of the asynchronous machine. From the
dynamic model of the machine, appropiate parameter estimation models based only
in the measurements of currents and the stator voltages are developed. Initially, one
technique for the estimation of the stator resistance of the machine based on the application
homopolar of voltages signals it is proposed. The considered model is analyzed
by simulation and experimentally. After that it is proposed one form of voltage wave
that allows to estimate all the remaining parameters of the machine without aid of
mechanical devices. The model is evaluated through experimental results.. Models for
induction machine are developed operating with incipient faults. Finally, one technique
incipient faut detection in real time for inter-turn stator winding faults in three-phase
induction motor is considered.
