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 ...
