Multiresolution Models of DC Traction Power Supply Systems With Reversible Substations
IET Electrical Systems in TransportationReversible substations (RSs) permitting bidirectional power flows can recover the regenerative braking energy of trains in DC traction power supply systems (TPSSs), increasing the energy efficiency of railway systems. To predict their effects on system dynamics and energy savings, the paper develops multiresolution models (MRMs) to simulate the RS ...
