LSC&S and KEPCO accelerate next-generation superconducting transmission network development

LS Cable & System and Korea Electric Power Corp. announced on the 21st that LS Cable & System and KEPCO together with the Korea Electro-technology Research Institute and Korea Electric Power Research Institute are embarking on extensive R&D to implement a next-generation superconducting power transmission network project initiated by the Ministry of Knowledge Economy to develop smart grid technologies until 2016.

This project, which aims at developing Korea into a leader of the global superconducting electric devices market, was initiated based on the necessity to develop large-capacity, high-efficiency and eco-friendly power transmission technologies using superconductor technology and apply them to actual transmission systems in an effort to effectively handle demand for next-generation power network implementation and to respond to the global trend of low-carbon green growth.

The objectives of this project are (1) to select systems for superconducting device application, to analyze the systems and derive system integration plans, and (2) to discover systematic support measures to commercialize the technologies and secure operation standards, maintenance procedures and engineering techniques. To fulfill the objectives, subtasks have been set to develop a transmission level DC (80kV or higher) / AC (154kV or higher) superconductor cable system manufacturing system, applications, and performance evaluation, operation and maintenance technologies; and a transmission level superconducting fault current limiter (AC 154 kV/4000 A, Refer to glossary), certification test, system applications, and performance evaluation, operation and maintenance technologies. At present, among the superconducting electric power devices, the transmission level superconductor cable and transmission level superconducting fault current limiter technologies are the closest to commercialization. Studies for system application are being actively carried out particularly in the U.S. and Europe.
