Abstract
Electrified Urban Massive Transportation Railway Systems require the supply of electric power that conforms to electromagnetic standards, safety levels and operational regulations. This paper presents a mathematical modelling of substations, autotransformers, power lines, and trains for a dual 50 kV AC railway system. The innovation of this study lies on the introduction of grounding points to reduce the rail voltage induction and assure appropriate safety levels. This study incorporates a description of Carson's Line in order to model accurately the self and mutual impedances between the conductors of the railway system. The results prove the effectiveness of the presented model with respect to grounding and safety.
