Abstract: This paper presents a combined dynamic parameter model (DPM) of a high speed train permanent magnet traction system using a dynamic reluctance mesh model and MATLAB Simulink. First, the dynamic reluctance model of the permanent magnet synchronous motor is introduced. Then the combined models of the traction system under i_d=0 and maximum torque per ampere control are built. Simulations using both constant parameter models and DPM models are carried out. The speed and torque characteristics are obtained. The results confirm that the DPM model provides higher accuracy without much sacrifice of time consumption or computation resource.

The paper presents usability of combined use of dynamic parameter model of PM motor and SIMULINK model of the high speed PM motor traction system under two different control modes (id=0 and MTPA control mode). Dynamic reluctance mesh model (DRMM) is used for the determination of the PM motor parameters under different conditions. Determined variation of the motor parameters is stored in the form of look-up table and used in the SIMULINK model of the PM motor traction system. The work can be interesting for the researchers in the field.
