Methods and Tools for Predicting Working Modes of Railroad Power-Supply Systems

This research is dedicated to design and implementation of a computer application for predicting the functioning of a railway power supply system (both on developing stage and in operational state). The process of creating a model for simulation of train movements is described in detail. Two working modes are considered in required hardware reliability estimation: a normal mode (standard conditions) and a breakdown mode (when one of the substations is down). Model analysis and implementation of the results obtained show their trustworthiness. While exploring model behaviour, we could determine minimum time interval between trains, estimate maximum possible current, voltage losses, as well as other parameters
