description: In this work, I considered the possibility of upgrading the electrical part of the TPP, relying on the existing 110 kV outdoor switchgear. Based on the needs of increasing generating capacities in connection with an increase in the number of consumers, a choice was made of generator equipment. Next, the corresponding power transformers were selected, capable of redistributing electricity from generators. Based on the selected power equipment, an electrical equivalent circuit was compiled for calculating short circuit currents. Using the obtained values of short-circuit currents, the choice was made of switching electrical equipment, conductive buses. The article also includes a part of the research of relay protection of the power unit, which involves the development of a project to prevent and protect against emergency and abnormal operating modes. The main regulatory documents and technical literature on this topic are analyzed. To protect the unit, the terminal of the domestic manufacturer NPP EKRA was chosen. The composition of the main as well as reserve protection elements was determined. In accordance with the previously obtained values of short-circuit currents, and also taking into account other conditions, the settings of the operation of relay protection devices were calculated.
