Abstract

Research and development of superconducting generation equipment has been conducted. As a part of the design research for the superconducting generator, the stability of superconducting field winding is being studied. The goal of this study is to formulate a design philosophy for a stable superconducting field winding in the presence of large disturbances. In the present paper, we describe the stable thermal equilibrium current of the superconductor, which is measured during the stability test. Modifying the equal area criterion presented by Maddock et. al., a simple graphical scheme has been presented and the minimum stable thermal equilibrium current was calculated.
