Abstract :
In this paper an AC drive system of a commuter train is investigated with regards to the load and line side perturbations. In order to carry out the study, a simple drive longitudinal train dynamical system has been developed, where the motor is driven by a voltage type inverter. This paper first describes and outlines the effects of load side perturbations, encountered as friction coefficient changes and normal load variations. Next, effects of line side disturbances on the drive system in terms of overvoltage and voltage drop due to the loss of contact between pantograph and catenary, are investigated
