Application of GWO-SVM Algorithm in Arc Detection of Pantograph

IEEE Access, 2020
High-speed train will produce pantograph arc during the driving process, which is harmful to pantograph-catenary system. In order to reduce pantograph-catenary system damage, a method based on Gray Wolf algorithm to optimize the binary Support Vector ...

Pantograph/Catenary contact formulations

, 2016
In this investigation, the pantograph/catenary contact is examined using two different formulations. The first is an elastic contact formulation that allows for the catenary/panhead separation and for the analysis of the effect of the aerodynamic forces,

Research of simulation and experiment on arc characteristics of gas mechanical switch

High Voltage, Volume 9, Issue 3, Page 626-635, June 2024.
Abstract An arc is the high‐temperature discharge plasma produced in the opening process of mechanical switches, which directly affects the breaking capability of a hybrid DC circuit breaker. According to the physical mechanism of an electric arc, the construction of an arc model for simulation analysis is an important technical means in the electrical

Analysis and suppression of operational overvoltage and inrush current for high‐speed trains by automatic phase‐switching technique

High Voltage, Volume 9, Issue 3, Page 733-748, June 2024.
Abstract When a high‐speed train approaches the insulated phase‐splitting section embedded between neighbouring power supply arms, the vacuum circuit breaker (VCB) installed on trains must be disconnected to maintain the traction power supply system as a no‐load condition for completing phase‐switching action, as the train passes through the phase ...

A new methodology to study the pantograph–catenary dynamics in curved railway tracks [PDF]

, 2020
The pantograph-catenary system is responsible to provide an uninterrupted energy supply to power electric traction railway vehicles. The analysis of the dynamic behaviour of the catenary and pantograph, as well as its interaction, has been the objective ...

Study of Electromagnetic Radiation From High‐Speed Train Voice and Data Antennae on the Health of Pacemaker Wearers

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2024, Issue 1, 2024.
In China, high‐speed trains have become a major means of transportation for the masses. When the passengers wearing pacemakers travel on high‐speed trains, electromagnetic environment in the carriage where the GSM‐R voice and data antennae are located should be concerned.

Pantograph/catenary contact force control

, 2015
In this paper, a new continuum-based pantograph/catenary model based on the absolute nodal coordinate formulation (ANCF) is proposed and used to develop an effective method to control the contact force which arises from the pantograph/catenary ...
