中文摘要：
在主动式短路电流控制措施中,超导故障限流器因其特殊的物理特性,具有可观的发展潜力。分析了YBCO和Bi-2212超导材料的电流密度、临界电流、温度等参数之间的关系,并结合电阻型和变压器型限流器的基本原理,借助PSCAD/EMTDC的自定义建模功能,建立了这两类超导材料对应的电阻型和变压器型限流器的自定义模型。在一个220 kV简化系统中进行测试,验证了该自定义模型的有效性。通过对仿真结果的对比分析,从响应速度、限流效果等方面讨论了限流器类型、超导材料对限流性能的影响。
英文摘要：
The superconducting fault current limiter （SFCL） is a promising technology in the active measures for shorl- circuit current limiting due to its special physical characteristics, and it is helpful fur improving the performance of SFCL to study its structural type and superconductive material. At first, the relationships among current density, critical current anti temperature are investigated for two materials, i.e. , YBCO anti Bi-2212. According to the basic principle of resistance-type superconducting fault current limiters （RSFCI,） and transformer-type superconducting fault current limiters （TSFCL）, the numerical models of RSFCI, and TSFCL are built by the user-defined function of PSCAD/ EMTDC for YBCO and Bi-2212, respectively. A case study is carried on a simplified 220kV power system, and the models is validated by the testing results. Finally, the influences of structural type and supercunduetive materials on responding speed and current-limiting effect are analyzed by the comparisons of current characteristics.
