description: This work is devoted to the reconstruction of the electrical part of the thermal power plant in order to increase the reliability of power output from the station, as well as the analysis of emergency events using oscillograms of transient processes. Problems that were solved during the work: 1) analysis of the current state of the thermal power plant equipment and development of recommendations on the scope of reconstruction; 2) reconstruction of the electrical part of the thermal power plant; 3) study and comparative assessment of the requirements of industry regulations for the oscillography function in relay protection and automation devices, RAS, SIPKE; 4) comparative assessment of software tools for analyzing oscillograms and oscillography characteristics; 5) analysis of disturbances in electrical systems based on oscillogram data in automation devices. During the reconstruction, oil circuit breakers of 110 kV and 220 kV switchgears were replaced with SF6 ones, and equipment that was not subject to reconstruction was checked, for which short-circuit currents were calculated. Calculations justifying the decisions made were carried out using the software "AWM SRZA", "PVK ARU", the analysis was performed using the software "Transcop", "Mechanotronics FastView 4.3", "Waves". The graphic part of the work was done in the AutoCad program. The result of the work is a design of the electrical part of the thermal power plant, as well as tables comparing oscillogram data, software for their analysis and the requirements of regulatory documents.
