Analysis of failures of components in a complex of backup power sources for signaling and communication devices on a railway section using the Petri net and Monte Carlo method

Abstract

This article presents an integrated approach to the reliability analysis of a backup power supply system for signaling and communication devices in railway transport. The model includes batteries, diesel generators, and alternative energy sources. A Petri net is used to analyze the logic of operation and switching between power sources, providing a visual representation of the system's structure and revealing potential conflicts. The Monte Carlo method is employed to quantitatively assess the system's reliability under various conditions. The simulation results demonstrate the impact of individual component failures on the overall stability of the system and help identify the most vulnerable elements, which is essential for subsequent optimization and improving the overall reliability of the power supply in railway infrastructure.
