The short-circuit current of transmission grid is greater and will bring damage more widely. It is of very important significance to limit the fault current of high voltage transmission grid. In order to reduce the manufacturing cost and enhance the limiting capability of superconducting fault current limiter

we proposed a novel topology of a split reactance type superconducting fault current limiter（SRSFCL）

analyzed the fault current limiting principle theoretically

and studied the modeling method. Moreover

we established a simulation model of 220 k V SRSFCL to study the current limiting characteristics and optimization methods of parameters of SRSFCL. The results shows that the novel SRSFCL can reduce the usage of superconducting tape

and enhance the fault current limiting capability and operating reliability of the SRSFCL. The study lay a foundation for development of 220 k V/1.5 k A SRSFCL prototype.
