Tuning of controller parameters for suppressing low frequency oscillations in electric railway traction networks using meta‐heuristic algorithms

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 ...

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 ...

Distribution of Currents in 2 × 25 kV Electric Railway Systems under Normal Conditions

International Transactions on Electrical Energy Systems, Volume 2023, Issue 1, 2023., 2023
This article shows a detailed analysis of the distribution of currents in 2 × 25 kV electric railway systems under normal conditions. The network equations are clearly formulated in a way that enables the presentation of a novel simplified analytical solution as well as the traditional numerical solution of the equation set.

Vulnerability Analysis of Catenary‐Bridge‐Track System

Shock and Vibration, Volume 2023, Issue 1, 2023., 2023
Continuous welded rails on bridges are extensively employed in high‐speed railways, where trains are predominantly electrically powered, and the open‐air catenary represents the weakest link in the system. Despite the widespread use of continuous welded rail on bridges for high‐speed railways, there exists a relative dearth of research on their ...
