Abstract
The time scale frame transformation is used to construct the analytic signal for single signal, and the large step simulation is carried out after the frequency reduction is rotated. It avoids the double frequency problem of Park transformation when the three-phase power system is asymmetrical, and also avoids the complexity of dynamic phasor method which needs to deal with the asymmetry problem in positive and negative zero order. Based on the principle of time scale frame transformation and the VBR model of induction motor, a time scale frame transformation model of induction motor is established. Then, the time scale frame transformation model of induction motor is programmed by Matlab software, and compared with the electromagnetic transient model of classical induction motor built by Simulink platform. The simulation example shows the accuracy and efficiency of the time scale frame transformation model of induction motor.
