“…[105] uses a dynamic simulation to study the effect of the regenerative braking of the high-speed trains over the unbalance of the main grid considering different substations power transformer configurations like V/V or SCOT. Finally, [106] presents a very detailed dynamical model with EMTP-ATP for studying a very specific problem. How switching in the main AC grid in a AC low frequency system at 16.7Hz affect to the autotransformer transients in bilevel AC traction networks.…”

In this paper, the authors review the mathematical models, simulation and analysis techniques and energy management systems proposed for railway power supply systems. The authors review both AC and DC railway feeding systems making special emphasis in those that consider new technologies like on-board or wayside energy storage, integration of renewable energies in the traction networks or the use of power electronic devices to increase the efficiency and controllability of the networks. The paper is divided in two main blocks studying DC and AC systems. In both parts, a review of the main simulation tools and models is presented but also a detailed list of specific cases of use of such techniques.

“…The hardness and complexity of AC motors to supply the high-power traction loads with the industrial frequency caused to establishment of 16.67/25 Hz system taking advantage of rotary frequency converters. The frequency transient, stability problems driven by electromechanical transients, and amplification of negative sequence current or imbalance in synchronous generators are the main PQ issues of these systems [6][7][8]. With the subsequent developments of technologies and high demands for transportation, industrial frequency-based ERPSs have become promoted and more popular.…”

Electric railway power systems (ERPS) as one of the most critical and high-power end-user loads of utility grids are characterized by outlandish power quality (PQ) problems all over the world. The extension and evolution of different supply topologies for these systems has resulted in significant and various forms of distortions in network voltage and current in all ERPS, the connected power system, and adjacent consumers. During the last years, numerous studies have been offered to investigate various aspects of PQs in a specific supplying topology. Variation in the supply structure of the ERPS and different types of locomotives has propelled the observation of different PQ phenomena. This versatility and development have led to confront considerable types of two-way interactive interfaces as well as reliability and PQ problems in ERPS. In addition, the lack of standards explicitly dedicated to ERPS has added to the ambiguity and complexity of this issue. In this paper, an extensive review of PQ distortions and phenomena in different configurations of ERPS is proposed and a systematic classification is presented. More than 140 scientific papers and publications are studied and categorized which can provide a fast review and a perfect perspective on the status of PQ indexes for researchers and experts.
