Active Control of Contact Force for a Pantograph-Catenary System [PDF]
Shock and Vibration, 2016 The performance of the high speed trains depends critically on the quality of the contact in the pantograph-catenary interaction. Maintaining a constant contact force needs taking special measures and one of the methods is to utilize active control to ...

Sliding Mode Control with PD Sliding Surface for High-Speed Railway Pantograph-Catenary Contact Force under Strong Stochastic Wind Field [PDF]
Shock and Vibration, 2017 As is well known, the external disturbance (especially the stochastic wind load) has nonnegligible effect on the operation of pantograph-catenary system, which may cause the strong fluctuation in contact force as well as the increased occurrence of ...

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 ...

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 ...

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 ...
