The diagnosis of bearings defects in electric machines has become an important area
of research in recent years. Most studies on the detection of bearing faults using vibration
measurements descended from sensors placed ...

We present in this work the study of the energy transformation produced by wind generators us before fact the modeling of
electromechanical drive multi-mass, composed of an electric machine and a mechanical load inter-connected ...
This memory proposes an appropriate solution for the optimization of reactive power, and voltage control through the incorporation of the flexible alternating current transmission systems “FACTS”. For this objective we ...
The economic dispatch problem is the determination of electric generation levels,in order to minimize the total generation cost
for a defined level of load. It’s a kind of management for electrical energy in the power ...
This work presents a contribution to the study of wet magnetic separation problems. It concerns the computation of the behavior of a random dispersion of particles of different natures and forms. To take into account the ...
The « Condition monitoring » of machines has become an art that can diagnose and precisely
potential defects to act quickly before the « break »!
Monitoring and diagnosis of electric machines represent a scientific and ...
"The research presented in this thesis concerns the mathematical modeling
and simulation of feeder of heating systems induction. It also shows the
different control strategies and the ehavior of the load in both modes ...
"The objective of this thesis is to provide a vector control
combined with an electric asynchronous motor. The
configuration of this system includes a photovoltaic generator,
a PV bus, a PV filter connected to a boost ...
