description: Theme of the final qualification work: âCalculation of steady-state and transient modes of the designed 110/35 kV power supply systemâ. In the course of this work was designed power system 110/35 kV, selected the appropriate equipment: generator, power transformers, cross sections of overhead line wires. Also, the steady-state mode was calculated using the software package âRastrWin3â with the subsequent optimization of the maximum and minimum load mode of EES, during which the on-load tap-changers of power transformers were used and the corresponding compensating devices were selected, which allowed to obtain the values of voltages in the nodes, satisfying the required quality condition. Calculation of currents and voltages of single-phase short-circuit at the fault location was carried out by two methods: analytical and experimental using the software package âEMTPâ. After that the comparison of the obtained results was carried out. Also, the dynamic stability of the EPS was calculated using the software package âDymolaâ with subsequent analysis and measures to improve it. Thus, the limiting short-circuit time was determined, satisfying the normative short-circuit tripping time at the considered 110 kV voltage class.
