Advancements and Impediments in Applications of High-Temperature Superconducting Material

Abstract

High-temperature superconductor (HTS) has proved to offer devices with higher efficiency due to its higher current density and higher power density. It has widespread applications in electrical power sector such as motors, transformers, faultcurrent limiters, energy storage devices and offshore wind turbines. All of these applications are still in progression. Still the mass commercialization of these applications has not been observed. This paper outlines a brief review of the development of HTS applications, their current status of development and the challenges.

AC Loss in High-Temperature Superconducting Bulks Subjected to Alternating and Rotating Magnetic Fields

“…With the help of superconducting technology, it is possible to develop small, light, and efficient electrical machines because HTS material enables a considerable reduction in size and an increase in machine efficiency [ 1 , 2 ]. There have been numerous applications of superconducting machines ranging from superconducting motors and generators to transformers [ 3 ]. Furthermore, novel technologies that are also made possible by superconductivity include superconducting fault current limiters [ 4 ] and superconducting magnetic energy storage [ 5 ].…”

“…Moreover, the commercialization of the HTS is hindered by the dissipative interactions that take place when these materials are subjected to the alternating magnetic field. It is known as AC loss or power dissipative loss and is brought on due to the displacement of vortices within the material [ 3 ]. This power dissipation phenomenon might put an additional load on the cryocoolers.…”

Experimental Setup for Measurement of AC Loss in HTS under Rotating Magnetic Field

“…This has triggered the use of HTS material in various large-scale power applications such as electric motors [1,2], transformers [3], fault current limiters [4][5][6], power cables [7,8], maglev trains [9][10][11], wind generators [1], and ship propulsion [12]. HTS material enables an increase in the efficiency of machines, along with a massive reduction in size, and, hence, it is possible to design compact, lightweight, and efficient electrical machines [13].…”

Three-Dimensional Numerical Characterization of High-Temperature Superconductor Bulks Subjected to Rotating Magnetic Fields

“…Over three decades, high-temperature superconductors have shown promising capabilities and possibilities for high-performance large-scale electrical machines [1]. HTS bulks fabricated from RE-Ba-Cu-O (RE stands for rare-earth element) by top-seeded melt growth technique have the ability to trap much higher magnetic fields at low temperatures, unlike traditional permanent magnets.…”
