Abstract:

The rotor flux-oriented vector control for five-phase induction motor considering the influence of the third harmonic component was studied in order to achieve a high performance of marine five-phase induction motor speed regulating system. According to the model of five-phase induction motor, vector control equations were established. After that the closed loop decoupling current model of both the fundamental and the third harmonic component were built based on the equations. The implementation of the five phase near four vector SVPWM considering the third harmonics component was discussed in detail. The starting and overload processes of the rotor flux-oriented vector control system for five-phase induction motor were simulated based on propeller load characteristics.The simulation results demonstrate that the five-phase induction motor control system has good static and dynamic responsiveness and strong anti-interference ability.
