A Research on Superconducting Fault Current Limiter and its Application Analysis

The exploitation of superconducting fault current limiter（SFCL） has been gained highly recognition by many countries and becomes one of the advanced subjects of current limiting technology research in recent years. In accordance with a type of main classification about SFCL,the article points out some traits and lacks of several types of SFCL. In view of researching hot spot at present,the operation principles and implementation of several SFCL with application value,such as the resistive type,magnetic shield type,saturated core type and bridge type SFCL are introduced emphatically in the article. Furthermore,it reviewed and discussed the main research results of the above type of SFCL in recent years.Based on the current situation of research and experience of engineering application,the article also points Out the key issues needed to be solved in pragmatizing research,which may be the reference to SFCL exploiture and the choice of current limiting measurement.
