description: The topic of the final qualifying work: "Design of power transformer relay protection". The main purpose of this paper is to study the relay protection of generator-transformer units. The choice of equipment devices for thermal power plants, the content of protections required for generators and transformers, and changes in the operation of the generator-transformer module under various types of faults are studied. In the course of the study the following works were to be carried out: Selection of equipment in the power system and calculation of short-circuit current. Selection and installation of relay protection and automation (RPA). Development of transformer model and eclectic part of TPP. Study of modes of operation of the unit "generator-transformer" of CHPP. In the process of design, the maximum and minimum operating short-circuit currents are calculated, so that the necessary protection devices against possible failures in generators and transformers can be installed. Appropriate current transformers and voltage transformers have been selected and all necessary protections have been calculated for the installation. Simulation of generator and transformer installations using matlab/simulink software in order to see how the waveforms change when adjusting for various types of faults. We can observe the effects of different fault types on the system and the generator and draw the conclusions needed to improve the protection of critical equipment.
