A study of the train running simulation for train propulsion system performance analysis

The aim of the paper is to analysis on train propulsion system and to study for energy saving. For this study, we make the program that simulates actual operation of the train route to get same experiment result. The train running simulation is performed from starting station to 4th station by using the route data of Deajeon city Metro Subway. The study for control method of electrical motor and energy recovery to save energy is selected. The train propulsion system is constituted as a M-G Set, which is realized via Space Vector Modulation(SVM) - Direct Torque Control(DTC), the energy consumption during train operation and energy recovery during breaking is simulated by Simplorer program. From this result, the energy consumption and recovery of train with SVM-DTC is studied.
