Transient analysis of 380-kV transmission system of Central Anatolia of Turkey

In this paper, switching overvoltages are studied on part of 380 kV interconnected network of Central Anatolia of Turkey, which contains six busbars that are interconnected with five different transmission lines of different lengths and geometries. The studies are carried out by an electromagnetic transient software program called PSCAD/EMTDC. Overvoltages that take place due to energizing a line on no-load condition and switching off a line under load condition are studied and voltage related curves are obtained and their magnitudes are calculated by means of the computer. This study has the characteristic of being unique, since it is the only computer aided study which has been done on the interconnected system of Central Anatolia of Turkey.
