Integrated railway smart grid architecture based on energy routers

Abstract

Railway power system is an inseparable part of the power system, therefore, the intelligent architecture of the railway power system should also be focused on. The unique power supply characteristics of the railway power system are analyzed and integrated railway smart grid architecture based on energy routers is proposed. Importantly, three corresponding resilient mode control methods are suggested for the proposed architecture. In the fourth section, a simulation model corresponding to the resilient control mode is built and the simulation results prove the feasibility of the proposed control mode. Equally, for the novel network-connected backbone router (NCBR), a 1 000 kVA, 27.5/10 kV NCBR engineering prototype is used to prove its effectiveness in practical applications. Finally, a differentiation analysis is given, followed by conclusions regarding the traditional power system and proposed system.

Impact of Superconducting Cables on a DC Railway Network

“…From the stand-point of modeling and simulation, the present work relies on past works simulating the railway network in dynamic regime for conventional technology on one hand [26][27][28][29][30] and the development of FE models to simulate superconducting cables on the second hand [31][32][33][34]. To date, there have been no attempts, at least to the best of the authors' knowledge, to simulate in transient a superconducting cable in a traction network as proposed hereinafter.…”
