Abstract

An electric traction system supplied at 2times25 kV with autotransformers is considered. The conductors arrangement is that of the new European High Speed Railway Line under construction. The system is analyzed with a validated multiconductor transmission line model with the aim of model simplification with reduction of the number of conductors and use of the lumped-circuit model. The scope is that of load-flow and voltage stability problems, which may be large-scale problems and benefit from model simplification and reduction of computational effort
