description: Topic of the final qualifying work: âDevelopment of an algorithm for automated analysis of an emergency incidentâ. As part of this work, issues arising during the design of thermal power plants were resolved using modern equipment and current technical solutions. During the work the following was carried out: 1) Selection of the block diagram of thermal power plants and main power equipment; 2) Calculation of short circuit currents at characteristic points of the circuit; 3) Selection of switching devices, conductors, current and voltage measuring transformers; 4) Selection of protection composition for 110 kV overhead lines; 5) Calculation of tripping settings for 110 kV overhead line protections. When performing the work, the optimal structural diagram of the thermal power plant was selected, as well as its main power elements, such as generators, transformers, and switchgear circuits were selected. Based on the results of calculating the three-phase symmetrical short circuit currents, switching devices included in the corresponding complete switchgears, conductors connecting power equipment, as well as current and voltage measuring transformers were checked and selected. Also, during the work, a choice was made of the composition of the protection of the 110 kV overhead line, extending from the TPP switchgear, with a tap. The short circuit currents were calculated in the EnergyCS TKZ program, based on the values of which the operation parameters of the 110 kV overhead line protections were calculated.
