Performances of Vector Control of Brushless Doubly-Fed Induction Generator Incorporate in Wind Energy Conversion System with TSR MPPT

Abstract

Currently, variable speed wind systems based on the Brushless Doubly-Fed Induction Machine (BDFIM) are the most used in Wind Energy Conversion System (WECS). The main features of BDFIM are high reliability due to its brushless operating, lower capital and operational costs. This work presents a field-oriented control scheme for a BDFIG acting as a variable-speed generator. The presented vector control is determined on the power-winding stator-flux frame and can be employed to control both the speed and the reactive power. In addition, use of wind speed sensors by an anemometer, and maximize wind energy extraction Tip Speed Ratio (TSR) Maximum Power Point Tracker (MPPT) is proposed. Several simulation results under different operating conditions are provided to prove the effectiveness of the presented scheme. The obtained results show the efficiency and validity of the proposed control strategy.
