Increasing the Operational Reliability of the Catenary System by Predicting Failures of Its Constructive Elements

EasyChair Preprint 5142

Abstract

the catenary system and accompanying high-voltage lines of the electrified railways are stochastic systems consisting of a large number of constituent structural elements, therefore, in the process of long-term operation; each element is subjected to various natural influences as well as dynamic influence caused by interaction with electric rolling stock and other equipment. All these factors lead to a decrease in the reliability of the traction power supply system of the electrified railways, and, as a consequence, are the cause of an emergency situation caused by the possible failure of any component of the system. The catenary system and associated lines are multi-wire systems and are subject to mutual electromagnetic influences. The solution for many scientific and engineering problems requires in the capacitive connections between wires in such systems. The paper provides a substantiation of an engineering methodology for calculating the probability of the structural elements` failure of a catenary system.

Keyphrases: catenary alternating current, failure probability, operational reliability, prediction
