This article considers a conversion device that ensures matching of the characteristics of the superconducting inductive (SPIN) energy sources and receivers of electric energy of the traditional performance in a power unit of autonomous perspective of the locomotive. Diesel-electric traction is a well-known and established technology for railways operators, but this alternative has a considerable non-ecological for the future because only electric traction has a considerable superiority. Besides, diesel-electric engines waste energy when resistive braking is used. This non-regenerative braking decreases the overall efficiency by 10-20%. With these premises, it is important to develop new strategies to increase the energy efficiency of diesel-electric haulage. To reach a better efficiency, a locomotive with energy storage (battery, super-capacitors) is theoretically proposed. Besides, the possibility of using a lower thermal engine with energy storage devices is considered too. This solution reduces diesel consumption and CO_2 emissions while being economically viable. It supposes an efficient energy management because the diesel-electric locomotive could act as a dispersed mobile generation (DMG) unit when working under electric overhead lines, and it can be used as a distributed resource for this specific electric power system.
