Electric Industry Restructuring New Imperatives in a Competitive Environment Increase Efficiency Improve power reliability and quality Enhance Market Access Address Environmental Concerns Optimize Siting Control Costs New Technologies Provide the Path to Success LOS ALAMOS

Advantages of HTS to End Users Much higher electrical currents Unique properties of superconductors More efficient carrier of electricity Higher power density cables and electrical equipment New solutions to Customer needs Lower operating costs LOS ALAMOS Significant environmental advantages

HTS Cable: Multiplying Grid Capacity User Benefits: –Higher Power Capacity x Conventional –Smaller right of way - easier siting/retrofits –Avoided construction - cost savings –Lower voltage - substation elimination –More environmentally acceptable - no oil LOS ALAMOS

Materials Science and Technology Division Superconductivity Technology Center Power Cable Retrofit Higher power density, lower cooling requirement, oil free Retrofit of 400' (~120 m) of three– 3-phase copper underground cables with a single 3-phase HTS underground cable Carries the same 2.4 kA total current at 24 kV (100 MVA) as the original copper cables and leaves 2/3 of conduit space available for future capacity Located within the Frisbie Substation of Detroit Edison, Detroit, MI

FCL: Benefits Compatible with existing protection devices Maximum allowable current adjustable Greater system flexibility - higher power Defer transmission/distribution upgrades Increased power reliability/quality Protects utility/customer equipment Uninterruptible power supply to grid LOS ALAMOS

FCL: Achievements Under construction: 17 kV, 45 kA, 765 MVA –Three phases –Handles 2 faults of 400 msec each, 15 s apart –Fault reduction of 80% –Tested 2000 A normal and 9000 A fault –Insulation Breakdown 110 kV –Cryocooler operation LOS ALAMOS
