ABASTRACT

This paper, we study the effect of exciter control system parameters on fault duration which

causes initiation of voltage instability and voltage collapses are accomplished. The effect of each

of the excitation control system parameters alone within its limits while remain parameters are

considered constant on the fault duration, which cause voltage instability initiation when a three

phase short-circuit occurs at certain node in the studied system. Also, searches for the effect of

varying the exciter control parameters each of them alone within its limit while, the remain

parameters are considered constant on the fault duration which cause initiation of voltage

collapse due to opening the transmission line between two nodes in the studied system.
