description: The work is devoted to the structural consideration of the functioning of a digital substation, as well as the analysis of its reliability. During the project, the following tasks were solved: 1. Analysis of changes in the structural diagram of the relay protection and automation system at the digital substation. 2. Description of possible malfunctions of individual elements of the relay protection and automation system. 3. Assessment of the reliability of the digital substation. 4. Analysis of the conducted test tests of relay protection and automation devices for a digital substation. In the course of the work, it was shown how the structure of the relay protection and automation system has changed, due to the application of the IEC 61850 standard. Variants of the structural schemes of the LAN at digital substations were considered. The description of possible malfunctions of relay protection and automation elements, which can lead to false, unnecessary or failures in operation, is given. Such reliability approaches as the logical-probabilistic method and the Markov reliability model are considered, graphs for compiling the Kolmogorov-Chapman equations are constructed. A description of multi-agent systems and their possible application for a relay protection system was also given. The existing test tests of devices for a digital substation are described and field tests of a digital substation are proposed.
