description: Theme of final qualification work: "Design of the district electric power system 220/110 kV"
 In the present work, design methods are reviewed and an electric power system (EPS) project is developed according to a given power supply scheme and initial pa-rameters (voltages, current loads, remoteness of objects).
 At the beginning of the work, the problems of existing 220/110 kV networks are described, the need for further improvement of the created networks in order to en-sure an ever-increasing demand for electricity and uninterrupted supply. The basis of the designed EPS is the reliability and safety of power supply, stability at the mo-ments of maximum loads. Particular attention is paid to the calculations and verification of system stability in emergency situations with various types of short circuit and the possibility of creating backup power.
 During the work, the necessary equipment, materials of the overhead line (OHL) were selected, as well as a network was designed. The operability of the designed EPS is verified analytically, with subsequent comparison of the results obtained in the Â«RASTRWINÂ» software package. The case of a 2-phase earth fault and possible consequences is reviwed and confirmed by calculations. Detailed calculations are accompanied by graphs and vector diagrams. The designed EES was tested for electrodynamic stability with limit values of short-circuit currents, and the maximum duration of short-circuit was determined at which the EES remains stable. Based on the results of the audit, conclusions were drawn about the full compliance of the designed EPS with the terms of reference and the feasibility of practical implementation of the project, as well as about the prospects for the operation of the EPS of the indicated voltages and the advisability of the integrated use of such systems in the regional power systems.
