V. Poroseva (CAPS), N. Lay (grad, SC), M. Y. Hussaini (PCSE) Developed a time–efficient computational graph-based algorithm for evaluating IPS survivability due to its topology under multiple simultaneous unrecoverable faults to compare different IPS topologies and design strategies. For a given number of faults, the algorithm generates combinations of faulty elements either deterministically or using Monte Carlo technique depending on the required accuracy of computations. Then, each combination is analyzed to determine how much power is available to loads after the faults. The algorithm supports parallel execution through OpenMP. Survivability analysis of a topology of 698 nodes with the total number of fault combinations ~2698 and the required accuracy of computations 0.5E-3 takes about 2 hours. 2009 ESRDC Team Meeting, 26-27 May, MSU 6 Algorithm development for automated widearea fault detection and location D.
