Expert system-based reconfiguration of shipboard power distribution systems

Shipboard electric power systems (SPS) are dynamic, complex systems that require continuous monitoring and fast controls to operate in a reliable and secure state. To enhance survivability of naval ships and meet reduced manning requirements, automatic reconfiguration for service restoration may be performed to restore the de-energized loads. This paper presents an automatic rule-based expert system method for reconfiguration of electric power systems on naval ships which determine the control operations necessary to restore power supply to de-energized loads after battle damage or cascading faults. A few case studies are presented to illustrate the effectiveness of the proposed method.
