  1. 16. Design of power supply system in DC electrified transit railways - Influence of the high voltage network

    University essay from KTH/Elektrisk energiomvandling

    Author : Denis Seimbille; [2014]
    Keywords : railway simulation; electric traction; AC DC load flow; high voltage network;

    Abstract : Urban rail systems such as subways and trams transport millions of people every day, oering a high level of service. Most of these systems are fed by direct current (DC). The design of the power supply network of DC electried transit railways is of great importance and requires the use of simulation models. READ MORE
