Abstract :
Increased generation capacity along with entrance of new power plants to the grid has caused increase in the level of short circuit in transmission grid substations. In this paper, methods for decreasing fault current used theoretically and practically are gathered briefly first. Then, short circuit level is studied in transmission substations at Azerbaijan regional electricity company region in 2014 to introduce practical methods to decrease fault current. Short circuit level of mentioned transmission grid is analyzed using DIgSILENT and appropriate methods are proposed to decrease fault current.
