INVESTIGATION OF THE DYNAMIC RESPONSE OF TWO INDUCTION MOTORS IN A LOCOMOTIVE TRUCK FED BY A COMMON INVERTER

For ac railway drives it is desirable to feed the parallel connected induction motors from a common inverter. However, the parallel operation depends on several influences, e.g. , the type of inverter, the mechanical transmission system and the characteristic of the wheel-rail contact. In order to understand the behavior a simulation model of the system including both the electrical and mechanical components of a truck was developed. The basic ideas of the model are reported. Simulation results are discussed for two induction motors fed from a current-source inverter. In particular, the dynamic response of the system to variations of the adhesion contact are elaborated.
