An Analysis of Superconducting Fault Current Limiter for Stabilization of Synchronous Generators under Unbalanced Faults

Abstract

Power systems are becoming larger and larger for meeting electric power demand. In that regard, as fault currents occuring in a power system tend to increase, measures against generator stability problems are expected to be more serious. On the other hand, in recent years researches and developments on superconducting fault current limiter (SFCL) are moving forward in accordance with the advancement of superconducting technology, which are hoped to be applied in practical power systems. This paper describes results of analysis about stabilizations of synchronous generators under balanced and unbalanced faults by SFCL.
