Preventive self-healing shipboard power distribution systems

Providing continuous mobility, power, and thermal management for shipboard combat systems in the presence of major interruptions involving cascading failures is a critical mission within the U.S. defense infrastructure. The typical AC radial shipboard electric power system (SPS) found on surface combatant ships consists of AC generators linked to ring-connected switchboards with radial distribution to loads below the generator switchboards. SPS supply power to the sophisticated systems for weapons, communication, navigation and operations of warships. This presentation discuss options for determining contingencies in the context of self-healing of SPS for material casualties or battle-induced failures. Also it presented the ranking methodology and approach used for determining critical contingencies and reconfiguration strategies. Lastly the method was using data generated by a computer simulated model of a typical shipboard power system.
