Modeling for power supply substation in maglev train system

초록

Since a power supply substation of the magnetic levitation train system includes an inverter which is necessary to change the frequency of power, it has a different characteristic comparing to any other railway system. Nowadays, a study is undergoing to determine rating of facilities constituting a power supply system and modeling that system. This paper proposes an analysis model for the power supply system of the magnetic levitation train using the 3-level inverter. Also, the analysis for output characteristic is performed using the PSCAD/EMTDC program. The control method about the output of 3-level inverter is also described for supplying power to the loads in magnetic levitation train system.
