The subject of the graduate qualification work is «Designing an electric power system 220/110 kV». In the course of this assignment following goals were fulfilled: 1. The selection of the electric power system equipment and verification of power linesâ conductorsâ sections and transformersâ parameters; 2. The manual calculation of electric power systemâs steady-state mode and modelling of on-peak and off-peak conditions using the «RastrWin3», during which compensating devices were applied and regulation of transformation coefficients was carried out; 3. The manual determination of asymmetrical short circuit currents and voltages, which resulted in the building of currentsâ and voltagesâ vector diagrams at the short circuit place, the aforementioned determination was also performed by using the «EMTP» software; 4. The research of electric power systemâs dynamic stability using the software «Dymola» and determination of interventions to improve the stability. |
