Aerodynamic noise from a train pantograph
Many studies have shown that when the speed of high speed trains exceeds around 300km/h, aerodynamic noise becomes the most significant noise source. The pantograph, or current collector, is mounted on the top of the train and is therefore not shielded ...

This article presents an active power filtering control method to suppress ripple power in the DC‐link of railway traction systems, including both the inherent second‐order ripple of single‐phase rectifiers and additional frequency ripples introduced by the pantograph–catenary arc.

ABSTRACT This work addresses the problem of developing a nonfragile sliding mode observer for fractional‐order complex networked systems (FO‐CNS) under stochastic network attacks. The proposed approach employs a combination of event‐triggered techniques. First, a nonfragile fractional‐order state observer is developed, enabling the design of a suitable

Simulation system of pantograph arcing
Perfect sliding electrical contact between pantograph and catenary can guarantee the safety and stability of locomotive. Pantograph arcing is one of the main factors of sliding electrical contact performance inelectrified railway system.

Availability Evaluation of Overhead Contact Lines Based on a Stochastic Colored Petri Nets Model
Due to their nonbackup characteristics and constant exposure to outdoor conditions, the performance of overhead contact lines (OCLs) will gradually degrade over time and further result in equipment defects or frequent failures. These issues significantly impact system availability and incur substantial repair costs.

Introduction of variability in pantograph-catenary dynamic simulations [PDF]
Currently, pantograph-catenary dynamic simulations codes are mainly based on deterministic approaches. However, the contact force between catenary and pantograph depends on many key parameters that are not always quantified precisely.

The influence of the fairing shape and cross winds on the aerodynamic characteristics of pantograph
The aerodynamic characteristics of pantograph have a great influence on the current collection of modern electric locomotive. It's an efficient method to install a suitable pantograph fairing to improve the pantograph aerodynamic performance.

In this manuscript, we proposed physics‐informed surrogate model, called FENet, for the first time to solve the interaction of pantograph‐catenary system. In recent years, much progress has been achieved in PCS modelling solutions. Existing solutions, however, suffer from two significant limitations: 1) An urgent concern arises regarding the ...
