Thermal Analysis in Railway Electrification Systems for bare conductors
This report is based on a Master’s Thesis [1], in which a tool to calculate the thermal behavior of railway electrification systems has been developed by means of iterative calculations based on heat transfer and energy conversion equations. The calculation method is implemented in Matlab, allowing to study the temperature of overhead bare lines. The aim of this tool is to size the section of the conductors (catenary, feeder) and calculate the recovery time of the system against unexpected contingencies. The input data is obtained from RailNeos 2.0, a simulator of railway electrification systems which is able to calculate the total energy consumption of the system, taking into account the implementation of accumulation devices. This tool was developed by Lemur Research Group of the University of Oviedo and CAF Tunrkey & Engineering.
