Algorithm development for evaluating the IPS survivability due to its topology

The paper presents a time-efficient computational algorithm for automated evaluation of the topological survivability of the integrated power system (IPS) in an all-electric ship. Topological survivability is the capacity inherent in the IPS architecture to maintain operations under adverse conditions such as, for example, combat damage. The IPS architecture determines whether power is available to loads after damage occurs and, therefore, is a key factor to consider in the analysis of the IPS survivability. Since survivability of an all-electric ship relies on the IPS survivability, clearly, the resistance of the IPS architecture to multiple faults should be analyzed at the early design stage and incorporated into the ship design. The algorithm proposed enables one to conduct such an analysis in a timely manner.
