System of the Autonomous Lighting of Railway Objects

Abstract

Railways run throughout Russia. There are sections of roads where centralized power supply lines are located far away or absent. It is difficult to regulate and ensure traffic safety at the sufficient level on such sections at the intersection of roads and railways at the same level. (Research purpose) The research purpose is to analyze the equipment available on the Russian market, powered by renewable energy sources, to solve the problem of guaranteed power supply to remote railway infrastructure objects and to select the most promising types, the effectiveness of which depends on natural and climatic conditions. (Materials and methods) The article presents a power supply system that can be applied to various artificial and engineering structures of general-purpose railway transport, such as crossings, bridges, tunnels, crossings in front of bridges and tunnels, sidings and others, for emergency or on-duty lighting. Such a system allows you to save electricity coming from a centralized power supply system, and in the case of an emergency shutdown, to provide power supply to the facility for a long time, and perform the function of backup power supply, but it takes on special importance in places where there are no centralized networks, when using it as an autonomous power supply system. (Results and discussion) The article presents a classification according to the categories of autonomous power supply systems, criteria of importance and power consumption of the objects, and gives the conditions for their use. The article describes a block diagram of the power supply system of a pedestrian crossing over a single track with energy reservation for up to three days. The daily energy consumption of a railway pedestrian crossing with lighting and railway traffic lights, installed the energy capacity of batteries with redundancy for up to three days, the power and number of photovoltaic converters are calculated. (Conclusions) An example of an autonomous lighting system for a railway pedestrian crossing with established technical parameters of equipment showed the social and economic efficiency of its application.
