Upgrading Study of Kuwait High Voltage Network 275 KV

Abstract

Kuwait transmission network (275 kV network) has a significant increase in short circuit level at  some grid and power stations substations above the system limitations (80 % of the rupture capacity of the system 63 kA).This increase results from the growth of power demand and the increase of transmission network complexity. New power stations will be added in the next few years. This paper describes a solution to the problem by splitting the transmission network into three zones as well as constructing new high voltage transmission network (i.e. 400 kV) and connects it with the existing 275 kV network. All the new power stations must be connected to the new 400 kV network and the connection to the 275 kV network must be stopped.
