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.

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.

Study on electric spark discharge between pantograph and catenary in electrified railway
IET Electrical Systems in Transportation, Volume 12, Issue 2, Page 128-142, June 2022., 2022 Abstract The electric spark caused by pantograph‐catenary (PC) electrical contact failure happens frequently, it is a kind of arcing phenomenon which can severely affect the current collection of PC. The theoretical analysis and modelling of PC electric spark are tried.

Variation in predicting pantograph–catenary interaction contact forces, numerical simulations and field measurements [PDF]
Vehicle System Dynamics, 2017 ABSTRACTThe contact force between the pantograph and the contact wire ensures energy transfer between the two. Too small of a force leads to arching and unstable energy transfer, while too large of a force leads to unnecessary wear on both parts. Thus, obtaining the correct contact force is important for both field measurements and estimates using ...

Characteristics of pantograph‐catenary arc under low air pressure and strong airflow
High Voltage, Volume 7, Issue 2, Page 369-381, April 2022., 2022 Abstract Pantograph‐catenary arc fault is the primary factor threatening the stability of the power transmission for high‐speed railway. The motion characteristics of the pantograph‐catenary arc under low air pressure and strong airflow is significantly different from the case under atmospheric pressure.

Voltage transient management for Alternating Current trains with vacuum circuit breakers
IET Electrical Systems in Transportation, Volume 12, Issue 1, Page 1-14, March 2022., 2022 Abstract Alternating current power supplies and rolling stock with 25 kV (50 or 60 Hz) and 15 kV (16.7 Hz) traction systems do not have the characteristics and behaviour of a typical three‐phase medium‐voltage distribution system. Switching inductive loads with a vacuum circuit breaker (VCB) in MV traction systems poses familiar challenges as well as ...

Energy harvesting approach for trackside health monitoring devices in railroads
IET Electric Power Applications, Volume 16, Issue 1, Page 100-111, January 2022., 2022 Abstract Design, modelling, simulation and lab test of a trackside electromagnetic energy harvesting (TEEH) approach for an AC electrified railway is provided in this study. By collecting the electromagnetic energy inspired from track current, an alternative energy source along the trackside can be achieved, which is not sensitive to weather and ...
