description: Theme of the final qualification work: "Reconstruction of an open switchgear 220 kV "Arkhangelsk CHPP". The purpose of the final qualifying work is the reconstruction of the main high-voltage equipment of the outdoor switchgear-220 kV of the ATES to improve the power supply system and stable operation of both the switchgear itself and the power facility as a whole. The question under consideration in this work is especially relevant at a given moment. A pre-static amount of new modern equipment has appeared on the electrical equipment market, which meets all the requirements for power facilities. Therefore, it is necessary to analyze the condition of the equipment installed at the facility under consideration and, if possible, perform its re-formation. Tasks that were considered in the course of the work: 1. Calculation of short circuit currents. 2. Selection of switching equipment and its verification. 3. Choice of microprocessor relay protection. 4. Calculation and verification of the ground loop and lightning protection switchgear. 5. Calculation of the economic benefits of the project. This graduation work is written taking into account the requirements that are imposed during the design and reconstruction of energy facilities.
