Quality of energy resulting from association converter- machine for the electric drive of a system of wind generation

Abstract

The work presented in this paper concerns, the quality of energy negated with wind power system, we were interested initially to impact of the choice of the type of PWM control of the converters on the output quality of energy and we were interested to the feeding and controls of doubly fed induction generator (DFIG) and the contribution which it will be able to carry its application in a wind chain conversion. The modeling of DFIG was presented, thus we applied the vector control in active and reactive generator power. Then we are interested in cascades based on a DFIG and back-to-back converter. The results obtained with simulation allowed the performance evaluation of the application of the asynchronous machine double power supply in the wind field.
