Numerical Models for Electric Train Energy-Efficient Operation
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2014, Vol 38, Issue 38
Abstract
The paper begins by presenting structure of the electric drives with traction induction motor used on locomotive fed from AC line. Are emphasized the main components of such a drive system: the main electric circuits, the mechanical part and the locomotive control. For the traction induction motors, which it is included in both the main electrical circuits and in the mechanical part, it is proposed the fictitious split into an „electromagnetic part” and into a „mechanical part”. In order to modeling the mechanical part, they are established the equations of useful movement and it is built the structural diagram corresponding to a locomotive with „z” traction identical motors. The mathematical model and structural diagram of the mechanical part respects all the running conditions. On the structural diagram basis it is built the SIMULINK model associated of the useful movement. The implementation of the SIMULINK models is made easily (because their identical topology), starting from the adequate structural diagrams. The SIMULINK model is used to calculate the energy consumption for different running regimes and different route configurations and to identify energy efficient train control methods, avoiding utilization of complex mathematical methods. The numerical models presented can be used, with small modifications, for the study by simulation of useful movement of any type of electric vehicle.
