description: The subject of the graduate qualification work is Â«Development of a model of the relay protection and automation system to assess its reliabilityÂ». This work is devoted to the reference model of the relay protection system for analyzing the operation of the relay protection system. Tasks that were solved during the work: 1. Development of a model of the primary connections of the substation; 2. Development of models of RPA terminals; 3. Creation of a program code that provides the creation of oscillograms; 4. Creation of a program code that provides the creation of event logs; 5. Conducting tests to verify the models. The work was carried out in the graphic programming environment MATLAB/Simulink. The creation and storage of the signal database is based on the built-in function of Simulink - BUS Editor. The result of the work was a model of the primary connections of the substation with the possibility of its expansion and complication, a model of relay protection and automation terminals with a completely recreated logic of operation and signal exchange between the terminals. At the same time, terminal models can be quickly adapted in accordance with the expansion or change in the scheme of primary connections. A program code was developed that allows obtaining oscillograms in the COMTRADE format and event logs from the data of the signals generated by the model. During the commissioning tests, the models were verified and a list of proposals was compiled to optimize several design solutions for the substation relay protection and protection system.
