A Visual Software System for Contingency Analysis and Proposing Preventive Actions to Achieve Secure Operation of Electric Power Systems

Abstract

In this paper, an important development in the SECURITY II software system, published earlier in the Journal of Damascus University, was achieved to analyze potential events and create preventive actions in order to ensure secure operation of electrical power systems. This new visual program system performs all functions of the previous program as well as a range of options, studies and comparisons. It also uses a graphical interface approach to insert in the power system data and complies it with the software engineering standards, as well as with analytical method which is based on approved language methodology, Unified Modeling Language (UML). In this research, a spiral model software was selected, which allowed getting reliable software product with the highest possible standards. The program was applied on a set of test standard networks and also used to analyze the security of a part of the Syrian Network for 230 kV. The effectiveness, flexibility of the program, and the accuracy of its results were all verified.
