Abstract
In this paper a new direct torque control system is proposed and is applied to doubly fed induction generator driven by variable speed wind turbine. In this control system the rotor flux and the electromagnetic torque are estimated based on the rotor voltage and currents measurements. Control system response is based only on wind speed profile. The control strategy is based on keeping harmonics at low order under the constraint of unity rotor power factor and also under decreasing torque ripples. Results are obtained from simulations show a very fast dynamic response for the control system with sensorless operation under wind speed variation.
