Contingency AND SECURITY analysis for power system network . Case Study _ NEC Grid

Abstract

The aim of this project is to investigate and understand the load flow analysis for power systems, during abnormal condition using (Ne plane) with the main focus on load flow analysis theories and computer application. The thesis define the power system security and the effect of load flow , contingency analysis to power system security , and how it effect of equipment of power system network . The thesis investigate Sudan national electricity cooperation during big load period s , then it summaries load flow solution to prevent applied contingency outages to the network and gave a summary, for load flow solutions, to prevent systems from breakdowns , locate the week point, reduce losses and give reliable efficiency and economic operation .
