Abstract

Iraqi National Super Grid suffers from out of synchronism of the system due to short circuit in the lines. The main goal of this work is to study the effect of optimum generation and reconfiguration of some transmission paths on transient stability improvement for Iraqi Network in case of short circuit in Haditha-Qaim line because it is one of the wrest lines. A programmable package build under Matlab5.3 was used to determine synchronous machines rotor angles as an indicator of transient stability. Sad Al-Mosul, Haditha and Nasiriya power plant were chosen to notice the situation of stability.
