Abstract:In today’s world, several measures are taken to achieve sustainable energy usage. The railway sector can be improved by recovering the braking energy. This recovering can only happen when a train is leaving, while another train arrives. To address this challenge there are two solutions. Temporary energy storage or supplying the braking energy back to the main grid by means of a reversible substation. This study compares the general characteristics of three energy storage systems (battery, flywheel, and supercapacitors) and two reversible substations (thyristor inverter and IGBT inverter). Additionally, an analysis and simulation of the two inverter types is conducted. Different commutation classes for turning off the thyristor in the inverter are discussed and compared. An energy analysis is conducted on the arriving and leaving trains for a busy station and a calm station (Utrecht Centraal and Deventer), and the different recovery systems are compared for the two cases. The results show that energy capacity is a significant factor in the amount of recovered energy. Another finding is that, relative to the station's activity level, energy storage has a greater impact on a calm station than a busy station. However, in absolute terms, the busy station recovers the most energy.
