220kV分裂电抗型超导限流器的仿真与优化设计
Modeling and Optimal Design of 220 kV Split Reactance Type Superconducting Fault Current Limiter
摘要
Abstract
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 kV 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 kV/1.5 kA SRSFCL prototype.关键词
