DIRECTIONAL VIRTUAL FLOW CONTROL OF THE DOUBLE STAR CAGE ASYNCHRONOUS GENERATOR
Keywords:
Virtual flow oriented control, Double Star Generator (GASDE), Virtual flux, PI-fuzzyAbstract
This article is devoted to the study of the performance of the double star cage asynchronous generator (GASDE) in isolated site. The control system consists of a GASDE connected to a dc bus and a load at the output of two PWM control rectifiers. A comparative study between the conventional control technique and the adapted control based on the introduction of the SVM- PI-fuzzy and a new flux estimator (virtual stator flux) in order to improve the quality of energy and to attenuate the harmonic of the current.
