Analytical Approach to Automatically Mitigate Electrical Faults Caused by Battle Damage

Power Superconductor and University of Pittsburgh EE Dept. will investigate a new analytical approach to mitigate bus faults on 4 kV and 13.8 kV ship power systems. The corporation has developed a fast response inductive insertion fault limiter for utility power systems at 15 kV and will analyze how this fault limiter can interface with 4 kV and 13.8 kV ship power systems using a differential inductive limiter with 4.2 millisecond (quarter cycle) response time. PSA has developed software and hardware to rapidly identify 15 different classes of power system faults within a 250 us response time using Labviews software. Analytical work will center on 70 MW generation systems and the specific ships: LPD-17, CVNX and DDX. Newport News Shipbuilding and Princeton Power Systems are team partners in this work for ship integration and logistics.
