Abstract

Predictive direct torque control (PDTC) has been proposed and well developed because of its excellent steady-state and transient performance. On the other hand, due to the elimination of proportional-integral regulator, direct virtual torque control was presented and proved to be an effective method for doubly fed induction generator (DFIG) grid synchronization. This paper proposes a novel DFIG grid synchronization strategy combining the merits of PDTC and virtual torque concept. The control system is very simple and robust while the smooth and fast grid synchronization is achieved.
