This paper presents a control strategy for the power flow management of a wayside energy
storage system based on a supercapacitor technology installed in a tramway network. The …

This paper presents an integrated hybrid railway power quality control system (HRPQC) to
deal with the power quality problems in the electrical railway supply system. The prominent …

Focusing on the freight-train dominant electrical railway power system (ERPS) mixed with ac-
dc and ac-dc-ac locomotives (its power factorε [0.70, 0.84]), this paper proposes a power …

Electric railway supplying systems (ERSSs) as one of the foremost and critical loads of the
grid have been faced with power quality (PQ) issues all around the world. Due to the various …

Facing the challenges of power quality problems and excessive neutral sections of
conventional two-phase electric railway supply system, the way of adopting railway static …

Essential imbalance and fluctuation of the mobile train load draw some problems, eg, three-
phase unbalance, reactive power, voltage and load fluctuation, harmonics, etc. in both …

This paper proposes a new type of cascaded ac-ac converter with phase-shift control and
reduced number of inductors. It can attain high voltage levels by using standard low-voltage …

The AC 2× 25 kV power supply system is a widespread solution in high-speed railway
networks. Owing to the operation of high-power trains in these systems, the 4Q converter …

This paper presents a novel cascaded multilevel PWM ac-ac converter that can solve
commutation problem. By cascading the single-phase PWM ac-ac converter that uses basic …

This paper presents a method to determine the voltage unbalance factor for a 25kV/50Hz
railway substation taking into account the power drawn by the trains. In order to correctly …
