Pantograph-Catenary System Modeling Using MATLAB-Simulink Algorithms

Abstract

-Contacts between pantograph and catenary are the most critical parts in the transmission of electrical energy for modern high-speed trains. Contact wire oscillations change combined force between pantograph and catenary, and the contact may even get lost. Therefore special pantographs and catenaries have been developed and further constructive changes are under development. A design criterion includes the permanent contact of pantograph head and contact wire at high speed and the reduction of both aero acoustic noise and wear. Because of complicated dynamic behaviour and very high costs for prototypes, all modifications and new design concepts for the pantograph/catenary system are essentially based on dynamical simulation. Traditional approaches focus on the catenary, which is modelled as set of coupled strings and/or beams, whereas simplified lumped mass models are used to describe the pantograph. Nowadays increased computer power allows considering applications with more refined pantograph modes (e.g. the elasticity of the pantograph) and active control components in innovative pantograph concepts.Keywords -interaction pantograph-catenary, mechanical multibody system, high performance computing in MATLAB

A new approach based on firefly algorithm for vision-based railway overhead inspection system

“…A system based on the Mayr arc model was proposed to detect arcs, and effects of arcs on AC current and voltage signals were analyzed [11]. A method based on a mathematical model was proposed to control the contact force in high-speed trains [12]. The mathematical model developed can be used for both active and passive controls.…”

Pantograf-Katener Arızalarını Önlemek İçin Derin Öğrenme Algoritmalarının Kullanımı

“…High-speed trains are used safely in various cities of European and Asian countries today. In Japan, which has a significant weight in high-speed train lines, the density of passengers is also above the world average (Matvejevs, 2010). It serves over 305 million passengers a year with over 100 trains.…”

“…The model created is based on the simulation results of the catenary stiffness varying with time at different speeds, it has been understood that the model gives good results at constant speeds but does not give good results at variable speeds. Matvejevs (2010) continued their studies in a simulation environment because he thought that reducing the contact force effect would only be possible with special designs and that the special design to be made would be costly. Xiaodong et al (2011) argued that abrasions are caused by vibration and that the control method to be applied to the pantograph-catenary system should be applied to the pantograph arch suspension to reduce these vibrations.…”
