Simulation of Electrical Power Plant Protection Using ETAP

Abstract

The main goal of this thesis is to simulate Electric power generation network because this network faced by blackouts several times this led to severe lack of production during blackout times specially when great amount of load from substations trip or one or more of on service generators stop suddenly this thesis find the best generators protection setting specially for over and under voltage fault protection setting and over and under frequency faults protection setting by using ETAP (Electrical Transient and Analysis Program) software as an analysis tool to perform generators protection setting for three different type of generators using for Sudan Nuclear Plant and draw the power network and simulate successfully many faults cases and find best generators protection setting. The new relay setting coordination had been applied to all relays in the five main substations as a result from this study. The sequence of operation is improved and as a result the total black outs frequency is significantly decreased.
