This paper presents the study of a variable speed wind energy conversion system based on a Doubly Fed Induction Generator (DFIG) based on a sliding mode control applied to achieve control of active and reactive powers exchanged between the stator of the DFIG and the grid to ensure a Maximum Power Point Tracking (MPPT) of a wind energy conversion system. The proposed control algorithm is applied...

In this paper present a sensorless maximum wind power extraction for variable speed constant frequency (VSCF) wind power generation systems with a doubly-fed induction generators (DFIG), to ensure stability and to impose the ideal feedback control solution despite of model uncertainties , using the principles of an active and reactive power controller (DPC) a robust sliding mode power control h...

This paper presents the implementation of broken rotor bar fault detection in an inverter-fed induction motor using motor current signal analysis (MCSA) and prognosis with fuzzy logic. Recently, inverter-fed induction motors have become very popular because of their adjustable speed drive. They have been used in many vital control applications such as rolling mills, variable speed compressors, ...

In this work, we are interested in improving the performance of a doubly-fed induction generator (DFIG)-based wind system, by applying sliding mode control strategy. The objective is regulation active and reactive power, also voltage frequency signal injected into distribution network. model proposed for based on technique with estimators. was validated simulation MATLAB/Simulink.

This paper presents the simulation of fivephase nine levels inverter fed five-phase induction motor. The poor quality of voltage and current of a conventional inverter fed induction machines is due to the presence of harmonics which increases their losses. For five phases induction motor fed from multi-level inverters, the current stress of the semiconductor devices decreases, torque ripple is ...
