| Summary: | Aiming at the problem of low power factor and efficiency of the asynchronous motor in the steady-state operation of the asynchronous generator in the traction power generation system of the diesel locomotive, the zero reactive power and the maximum torque-current ratio control method was adopted. Firstly, the electromagnetic relation of the induction motor in the rotating coordinate system was analyzed, and the equations of zero reactive power and maximum torque current ratio(MTPA) control were discussed. Secondly, under the limitation of the intermediate DC link, the field weakening curve of the asynchronous generator was analyzed, the minimum current operating point was found, and the current trajectory planning was completed. On the premise of ensuring the stable operation of the traction power generation system, the working efficiency of the motor and the inverter was improved. Finally, simulation of system was taken out with Simulink software. |
