Abstract

This paper proposes a future power system having superconducting power cables, transformers and fault current limiters (FCLs). The proposed system is a new concept of superconducting power system (SPS) applying distributed switching stations for metropolitan areas. The SPS utilizes the large-capacity and environment-friendly characteristics of superconducting power equipment. The switching stations supply power load of distribution local areas with electric power. If the SPS is realized, we can resolve some problems in expanding power facility in metropolitan areas where power load is concentrated. In addition, the proposed system can maximize economic, social and environmental benefits. We carried out basic studies on the structure design and technical/economic evaluation of the SPS.

Superconductivity technologies) program as a part of the frontier project promoted by the Ministry of Education, Science and Technology [9]. Along with the development of superconducting power equipments, there are on-going researches on the power system application of the equipments [10]–[17]. Particularly, a basic study is being carried out for the application of 22.9 kV superconducting cables, 22.9 kV SFCLs, and 154 kV/22.9 kV superconducting transformers to the future power system [16]. In this paper, we proposed a new power system of the SPS applying distributed switching stations, and studied its basic economic and technical issues. It is expected not only to solve the fault current problem and the site problem of electric power equipment in downtown but also to change the paradigm of future power systems.
