Florida State University, USA

The Center of Advanced Power Systems (CAPS) at Florida State University (USA) has a unique test and demonstration facility for HTS power cables.

With support from the U.S. Navy, Office of Naval Research (ONR) and the U.S. Department of Energy, CAPS has established a unique test and demonstration facility with one of the largest real-time digital power systems simulators along with 5 MW AC and DC test beds for hardware in the loop simulation. The center is supported by a research team comprised of dedicated and highly skilled researchers, scientists, faculty, engineers, and students, recruited from across the globe, with strong representation from both the academic/research community and industry.

The lab test and demonstrate HTS (DC), superconducting power cables. These cables are typically operated in the 20-50 Kelvin range.

They use (amongst others) a Stirling Cryogenics SPC-1 cryogenerator and several CryoZone CryoFans and heat exchangers to achieve these temperatures.
