description: The object of the research is the power supply system of the processing plant of the Archikoy mine. The purpose of the final qualifying work is to develop a project for an electricity supply system. In the first part of the work, the following tasks were solved: - the calculation of the electrical loads of the main and secondary consumers of electricity of the industrial site has been carried out; - power transformers for 110/6kV voltage and 6/0,4kV voltage have been selected, as well as transformers for their own needs; - selection of power supply schemes and justification of layout solutions for 110 kV and 6-0,4kV voltages was made; - the calculation of the short-circuit currents of the 110kV line, 6kV bus, 6kV main equipment lines, as well as 0,4kV outgoing lines has been performed; - the selection and justification of the main switching equipment at a voltage of 110 kV, 6 kV, 0,4 kV was made; - the choice of the cross section of wires and cables was made based on the conditions of long-term permissible currents, economic density, thermal resistance, non-ignition. In the second part of the work, the following tasks were solved: - a complete 6-0,4kV power supply scheme has been developed; - schemes for connecting diesel power plants have been developed.
