Understanding the Response of Superconductors in Electrical Faults to Develop Resilient Power Dense Distribution

Abstract

United States Navy is moving toward all-electric ships and other platforms to enable nextgeneration weapons and communications systems while at the same time increasing efficiency,operational flexibility and enhanced projection of force. To achieve these goals, a high powerdense electrical distribution network is essential to move electrical energy easily, efficiently, andeffectively. High Temperature Superconductors (HTS) that are already deployed for degaussingapplications on ships are being developed for power system components. HTS power cables havebeen demonstrated to support the power densities required. Complex power systems often generateelectrical faults during which the voltages and currents surge to values that are significantly abovethose of the normal operating conditions. Power cables on ships have to survive the faults withoutcatastrophic damage. The proposed basic research effort will generate the knowledge essential toassess the response of HTS in fault conditions on future Navy platforms and to devise intelligentdesign features that will enhance fault tolerance and resiliency of HTS distribution cables. Theproposed basic research will address the basic understanding and knowledge gap in the area offault tolerance of HTS cables. The proposed research encompasses subsystem electrical andthermal models as well as experimental investigations. The results of this basic research effort willgenerate the knowledge base that will enable effective HTS cable designs that will be efficient,cost-effective, and contribute to resilient electrical distribution networks for Navy platforms.The work will be performed at the Center for Advanced Power Systems of Florida StateUniversity located in Tallahassee, Florida. The Principal Investigator, Professor Sastry Pamidi andhis research group members have extensive experience in HTS materials and devices and theResearch Center have the required research facilities and equipment to effectively conduct theproposed research. The team has performed on several Navy related research projects and isknowledgeable in the Navy systems and needs.The technical approach will involve literature study on various potential faults in the powersystems of Navy platforms, investigations through computer models of HTS cables, andexperimental investigations on HTS cable sections.The personnel involved in the research effort are the principal investigator, research staff,graduate students at Florida State University and collaborators from Georgia Institute ofTechnology.The outcome of this fundamental research is the knowledge that is essential to design faulttolerant power cables including HTS cables and to incorporate new design features to enhanceprotection and resiliency of HTS power cables and the power systems of Navy platforms.
