IET Electrical Systems in Transportation, Volume 13, Issue 2, June 2023., 2023 Due to the interaction of electric multiple units (EMUs), and the electric traction networks, low frequency oscillations (LFOs) appear that leads to traction blockade and overall stability related issues. For suppressing these LFOs, coronavirus herd immunity optimiser (CHIO), a recently developed meta‐heuristic based on the herd immunity concept in ...

Operation and Control of an Active Power Collector for Roadside Feeding Electric Road System
IET Electrical Systems in Transportation, Volume 2023, Issue 1, 2023., 2023 The integration of electric vehicles (EVs) as an environmentally sustainable alternative to traditional fossil fuel cars faces a range of technological obstacles, including battery technology, charging infrastructure, and standardization. Dynamic conductive road charging (DCRC) of EVs at high speed has the potential to overcome the technical ...

IET Electrical Systems in Transportation, Volume 2023, Issue 1, 2023., 2023 Droppers and jumpers are important components of railway overhead line electrification. Their effective maintenance is critical for the railway’s safe and reliable operation; the consequences of their failure can be disproportionally serious. This paper systematically analyses the components’ failure by applying the method of failure modes and effects ...

Vibration Analysis of Traction Drive System Components Based on the Field Test for High‐Speed Train
Journal of Advanced Transportation, Volume 2023, Issue 1, 2023., 2023 The traction drive system of a high‐speed train is the key subsystem of a high‐speed train, which controls the driving and braking of the train through electromechanical coupling, and determines the running speed, power quality, and comfort of the train.

IET Electrical Systems in Transportation, Volume 12, Issue 4, Page 238-250, December 2022., 2022 Abstract With the increase of train speed in electrified railways, the increasingly violent interaction of pantograph–catenary (PC) makes the PC detachment arc an extrusive phenomenon, especially in the double‐pantograph–catenary (DPC) system. Despite a large number of research studies have focussed on the PC arc in a single pantograph system, the ...

IET Electrical Systems in Transportation, Volume 12, Issue 4, Page 223-237, December 2022., 2022 Abstract Medium‐voltage DC (MVDC) electric railway systems have several advantages over conventional DC and AC railway electrification systems. These advantages include higher capacity, possibility of connecting to power networks at lower voltage, removal of neutral sections, smaller line voltage drops, and longer distances between traction power ...

The Journal of Engineering, Volume 2022, Issue 11, Page 1076-1085, November 2022., 2022 Abstract Vibration compensation in track displacement monitoring is explored by using rail image feature points. The key point is to compare the image of the rail to be tested with the image of the standard rail. A downstream section of Metro Line A is selected for real time analysis of image.

Effect of Pantograph’s Main Structure on the Contact Quality in High-Speed Railway
Shock and Vibration, 2021 In general, the electrical energy is provided to the high-speed train through the pantograph-catenary sliding contact. The variation of the dynamic contact force is expected to be small enough to keep the good current collection quality and to extend the
