Matlab-Simulink Simulation Model of Electric Multiple Unit (EMU) Series ŽS 413/417 in Traction and Electric Braking Mode

In the paper, the Matlab-Simulink model of simulation of operation of the ŽS 413/417 series EMU (electric multiple unit) in traction and braking mode is exposed where changes are observed: stator currents of three-phase traction motors, traction electric motor speeds and EMU, electromagnetic torque on the rotor shaft of the traction electric motor and DC (direct current) bus voltage. The model allowed review of the listed parameters for: different allowed values of contact network voltage and total voltage distortion at the place of connection of the EMU to the contact network, different mechanical loads of EMU and traction electric motor and different train speeds and rotation of traction electric motors. Appropriate conclusions were made through the analysis of the simulation results obtained.
