Failure Mode Analysis and Maintenance of Railway Overhead Line Rigid Stainless Steel Droppers and Multi‐Strand Copper Jumpers

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.

Characteristic analysis of pantograph–catenary detachment arc based on double‐pantograph–catenary dynamics in electrified railways

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 ...

Medium‐voltage DC electric railway systems: A review on feeding arrangements and power converter topologies

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 ...

Vibration compensation for railway track displacement monitoring system using biomedical image processing concept

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.

GENETIC ALGORITHM-PID CONTROLLER FOR MODEL ORDER REDUCTION PANTOGRAPHCATENARY SYSTEM [PDF]

Applied Computer Science, 2021
Controlling the contact force between the pantograph and the catenary has come to be a requirement for improving the performances and affectivity of high-speed train systems Indeed, these performances can also significantly be decreased due to the fact ...

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

Experimental stand and researches on pantograph-catenary contact force control using chaos theory

Journal of Physics: Conference Series, 2021
Abstract Due to the oscillating behaviour of the pantograph and the catenary during the movement of the locomotive, the contact force changes to wide limits, resulting in electrical sparks with consequences: premature wear of the contact wire, electromagnetic disturbances, energy loss.

Carbon brush wear calculation in marine environment based on temperature field analysis

IET Renewable Power Generation, Volume 16, Issue 11, Page 2267-2278, 17 August 2022., 2022
Abstract In the marine environment, the working environment of the doubly fed wind generator carbon brush and slip‐ring system is complicated, salt spray deposits and seawater erosion affect the temperature field and contact surface friction factor leading to carbon brush wear increase and shortened replacement cycle.
