His research interests include fabrication, characterization, and application of high temperature superconducting wires with emphases on performance, property, quality, and testing. Dr. Zhang serves as an expert in the Working Groups under IEC/TC90.

Presentation Description

High Temperature Superconductors – Near Term Power Applications

High temperature superconductors (HTS) hold a great promise in their practical application in many areas including in power industry. However, 30 years after their first discovery, the large-scale application of these intriguing materials remains as a dream. There are still many challenges along the road and a major one has been in the technology to produce cost-effective and industrial-grade materials. In this talk, I will first review the progresses in the technology for the manufacturing of practical HTS materials, with a focus on the long-length REBCO-based wires or the so-called second-generation (2G) HTS wires. The performance and properties of the state-of-the-art materials that are important to practical applications are introduced. As the HTS materials are becoming available and affordable, we have seen their initial entries in some of the application areas. I will highlight the technological advancements in HTS-based cables, FCLs, SEMS and fusion reactors, prospective HTS applications in future power grid.
