Superconducting transformers for power, energy, and transportation applications: An introduction to superconducting technology for transformer engineers
Superconducting transformers have advantages over their conventional counterparts, making them a killer technology in electric power grids and renewable energy systems, as well as transportation applications requiring high power transmission capacity. Compared to conventional transformers, superconducting transformers offer low weight, small size, high fault tolerance, fault current limitation, significant overload capability, and no environmental issues or fire hazards. Power systems and microgrids are candidates for the implementation of superconducting transformers when they include distributed generation and renewable energy, especially wind farms. Transportation applications also benefit from the highly compact structure and lightweight superconducting transformers. This paper introduces opportunities offered by superconducting transformers for supplying power with high reliability, stability, and safety
