Abstract: During the operation of doubly fed induction generator of wind turbine, the output value of speed sensorless direct torque control fluctuates abnormally due to the uncertainty of parameter changes. In order to ensure the frequency stability of doubly fed induction motor, a speed sensorless direct torque control method of doubly fed induction motor is proposed. The synchronous speed and slip speed of the rotor flux linkage are calculate, and the observed speed of the generator is obtained. The vo... More
