Feasibility of Appilcation of Superconductivity to Power System

Abstract

If we rely only on the conventional technology, it may be difficult to meet the recent requirements to electric power system such as further improvement of the quality of electric power supply, environmental compatibility and so on. Some of the limitations of comventional technology can be broken through by the application of superconductivity technology. Roughly speaking, superconductivity-applied components which have relatively high feasibility are superconducting generator, small capacity SMES and liquid nitrogen cooled superconducting cable. To use them practically, reliablilty, maintenability, controlability and economy have to be improved.
