The subject of the graduate qualification work is «Selection of equipment and calculation of electrical modes of electric power system 330/110 kV». In the given graduate qualification work an EES with voltage steps of 330/110 kV was investigated. In the course of the work carried out, many tasks were solved, and more specifically: 1. The choice of power equipment and the cross-section of the EES wires was made in accordance with the data of its design option. 2. The calculation of the steady-state mode of EPS operation was carried out manually and using the software "RastrWin". 3. The calculation and study of an asymmetric short circuit, namely a twophase earth fault K(1,1), have been carried out. 4. The analysis of the dynamic stability of the EPS and the methods of increasing the dynamic stability have been carried out. In the course of the work, various measures were taken to optimize the mode (compensating devices were installed in the load nodes) and to improve the dynamic stability. |
