Analysis of Single and Multiple Line Contingency in a 62 Bus Indian Practical Power System using Track Structure Algorithm Approach

This paper presents an analysis of multiple line contingencies in a power system. Two evolving contingency screening methods are described for faster screening of important double-line contingencies that occur in a system. These methods analyze the complete double line contingencies without considering all possible double line outages, instead of taking only a few outages for the complete analysis, which in turn reduces computational effort and time as well, by using predefined power system sensitivity factors. The method described in this paper is used in an Indian 62 Bus power system, and promising results are obtained.
