The Technology Impact & Problems of Superconductivity Applied Components on Future Power System in Korea

If we rely only on the conventional technology, It may be difficult to meet the recent requirments to electric power system such as further improvement of the quality of electric power supply, technology problems environmental compatibility and so on. Nowadays, power engineers much interest in applying new technology to power system industry. It is confirmed the technology of superconductivity applied components plays an important role in solving the problems of power system, because superconductors, used in suitable applications, can make electric power equipment smaller, lighter, more efficient and perhaps with better dynamic response. Two specific applications are considered here : electric machinery (Generators, Superconducting Magnetic Energy Storage, Transformer, Current limitter) and transmission line. The paper addresses the limitation of conventional technology, the technology impact & problems of superconductivity applied components to future power system from qualitative and some quantitative viewponts. The paper close with questions posed to simulate thinking on how superonductivity might be applied to power systems on a holistic basis.
