description: Topic of the final qualifying work: âSelection of equipment and calculation of electrical modes of the 220/110 kV electric power systemâ. The purpose of this final qualifying work: âselecting power system equipment, calculating maximum and minimum load modes, as well as emergency mode in the form of an asymmetrical short circuit, finding the values of short circuit currents and voltages, assessing its dynamic stability and finding measures to improve it.â Execution steps: 1. Selection of system elements (generators, generator transformers, power transformers, autotransformers and power line brand) 2. Calculation of the steady state of the power system. 3. Calculation of asymmetrical short circuit currents. 4. Assessing the dynamic stability of the system and developing measures to increase the level of dynamic stability. After selecting equipment and implementing a steady state using the RastrWin software, discrepancies with the rated voltages on the loads were identified, as well as a lack of reactive power in the system. To solve this problem, we installed banks of static capacitors on the loads, however, when implementing minimum EES loads, the presence of compensating devices seems unnecessary, so in this mode they were turned off. A two-phase short circuit to ground was implemented as an emergency mode of the system using the EMTP software package and the method of asymmetric components; as a result, the values of currents and voltages obtained using the theoretical and practical method converged within the error limits. After proving the stability of the system, a two-phase short circuit to ground was recreated, and after a three-phase short circuit, measures were developed for the latter to increase dynamic stability.
