1 High-Temperature Superconducting Generators for Direct Drive Applications OZAN KEYSAN Institute for Energy Systems The University of Edinburgh April 2011

2 Ozan KEYSAN 2 Superconductor?  Abolish the OHM’s Law Kakani2009 Zero Resistivity

3 Ozan KEYSAN 3 MERCURY  The First Superconductor Material  Discovered in 1911  Critical Temp = 4.2 K (-269 C)

4 Ozan KEYSAN 4 Other Superconductors Schiferl2006 LIQUID NITROGEN?? OH NO!

5 Ozan KEYSAN 5 Infinite Current? Unfortunately NOT.

6 Ozan KEYSAN 6 YBCO (YBa 2 Cu 3 O 7 ) Current Density > 200 A/mm2 (5-10 A/mm2 for copper)

7 Ozan KEYSAN 7 Perfect Diamagnetism

8 Ozan KEYSAN 8 Applications: MagLev Train

9 Ozan KEYSAN 9 Applications: Large Hadron Collider  Superconducting Magnets Up to 16 T, Normal PM ~1.5 T

10 Ozan KEYSAN 10 Applications: MRI

11 Ozan KEYSAN 11 Power Applications Courtesy AMSC, InnoPower Superconductor  Transmission Lines  Fault Current Limiter

12 Ozan KEYSAN 12 Power Applications : Electrical Machines Courtesy of Siemens, Converteam (ALSTOM)  Siemens: 400 kW  Converteam (ALSTOM): 5 MW HTS

13 Ozan KEYSAN 13 Power Applications : Electrical Machines  36.5 MW, 120 rpm (U.S. Navy, AMSC) Courtesy of AMSC

14 Ozan KEYSAN 14 Wind Turbine Applications? M. Lesser, J. Müller, “Superconductor Technology – Generating the Future of Offshore Wind Power,” BARD 5MW

15 Ozan KEYSAN 15 Direct-Drive Solutions

16 Ozan KEYSAN 16 Cost Comparison (HTSG vs. PMG) Lesser2009

17 Ozan KEYSAN 17 Types of HTS Machines  Rotating DC Superconducting Field  Most Common Type  Transient Torques on HTS wire  Cryocooler Coupler + Brushes  Low Reliability  Cooling Times  Magnetized Bulk HTS  Very Difficult to Handle  Demagnetization  All Superconducting Machines  AC Losses on HTS wire

18 Ozan KEYSAN 18 Reliability?  Stationary SC Coil  No Cryogenic Coupler  No Brushes  No Transient Torque on SC  Simplified Cooling, Isolation  DC Field  No AC losses  Maximized Current

19 Ozan KEYSAN 19 Homopolar HTSG

20 Ozan KEYSAN 20 Homopolar HTSG

21 Ozan KEYSAN 21 Axial Bipolar HTS Machine

22 Ozan KEYSAN 22 Bonus: Bipolar Linear HTSG  Suitable for WECs

23 Ozan KEYSAN 23 Transversal Flux HTSG

24 Ozan KEYSAN 24 Hasta la Vista! Thanks.
