Project - master thesis. Aim of the project is to simulate the work of Juodkrantes transformer substation in 35 kV network in two modes: with an isolated neutral and grounded through the resistance. Moreover, to determine the impact of transient surge processes influenced by neutral grounding resistance. The theoretical part analyzes the different transformer neutral grounding techniques and their impact on the transient process. There is also analysed transformer neutral grounding mode prevalence in the world. One phase and three phase faults were simulated in all modes, phase currents and voltages were measured in each case. The influence of transient processes that neutral impedance transformer size makes was determined. Transient processes during the faults are displayed graphically and described. Modeling data summarized. |
