The article is devoted to assessing the possibilities of integrating microprocessor terminals of protection and automation into digital systems used in railway transport. The article describes the development of options for building local area networks adapted to work together with microprocessor terminals for protection and automation of feeders in the contact network for the traction power supply system of 25 kV, 50 Hz AC. The results of the analysis of the composition for switching equipment on the example of existing traction substations of the Far Eastern Railway were used to make a conclusion: developing several variants of schemes is important for building a local computer network. Schemes of local computer networks are proposed for the use of microprocessor protection and automation terminals from various manufacturers and for the presence or absence of regular servers and elements of automated control systems.
