摘      要：The design progress of superconducting fault current limiter(SFCL)for transmission voltage is presented,with a focus on the results of recent key experiments that have led to a state‐of‐the‐art high‐voltage high‐capacity super‐conducting current limiting techniques:the resistive alternating current(AC)SFCL,saturated iron cores AC SFCL,and resistive direct current(DC)*** main driving factors for designing SFCL in these projects are the preparation of high‐performance superconducting materials,the development of large‐scale superconducting current limiting winding,system testing,and operation *** on the authors’experience with both AC and DC SFCLs,this paper focuses on the main design aspects of resistive SFCL at transmission *** relationship between the hot spot caused by the inhomogeneity of long superconducting tape and the overall parameter selection is *** addition,the thermal calculation based on the current limiting resistance and a real‐time current curve is also proposed for the parameter design of the current limiting winding.
