In this paper, a novel direct torque control of doubly- fed wound rotor induction machines is studied. A rotor unity power factor based direct torque control strategy is proposed. By keeping the rotor power factor to be one, a switching-table- based hysteresis direct torque control system is built and the corresponding rotor voltage vector table is obtained. The feasibility of the proposed method...
In this paper, a novel direct torque control of doubly-fed wound rotor induction machines is proposed and applied to variable speed wind power generation systems. The proposed control strategy was developed based on the control of the rotor power factor. By keeping the rotor power factor equal to one, a switching-table-based hysteresis direct torque control system was built and the corresponding rotor...
In this paper, a stator power factor adjustable direct torque control of doubly-fed induction machine is proposed. The selection of rotor voltage vectors is performed based on the torque and the stator inactive current. The control system is built and the rotor voltage vector table is given. The feasibility of the proposed control strategy is examined through Simulink simulation experiments. Good...
