Control Of a Doubly fed Induction Machine for a Wind Application

Abstract

The wind energy systems using a doubly-fed induction generator (DFIG) have some advantages due to variable speed operation and four quadrants active and reactive power capabilities compared with fixed speed induction. In this article, A new Dual-Direct Torque Control scheme is developed with flux model of DFIM. It is based on the principle of a double flux orientation of stator and rotor at the same time. Indeed the main idea is to maintain stator and rotor fluxes to their nominal values The proposed method shows good results simulation
