摘　　要：传统桥路型超导故障限流器存在诸多不足。文中提出了一种组合型桥路超导故障限流器的设计。在阐述其工作原理的基础之上给出了主要的参数设计;根据应用工况在仿真软件MATLAB中对其性能进行仿真验证。结果证明:组合型桥路超导限流器可有效限制短路电流;基于网侧电流幅值的控制策略可有效控制超导线圈的投切。由于组合型桥路超导故障限流器的优异性能,将其作为超导储能限流系统的设计方案。To compensate the insufficiency of the traditional bridge-type superconducting fault current limiter（SFCL）, a combined bridge-type superconducting fault current limiter is designed. Its working principle and main design parameters are discussed. Simulation is conducted via the software MATLAB to verify the performance of the combined bridge-type superconducting fault current limiter. The results show that the combined bridge-type superconducting fault current limiter can effectively limit fault current, and the control strategy based on grid current amphtude can effectively control the switching of superconducting ring. Consequently, this combined bridge-type superconducting fault current hmiter can be adopted as the design solution for the superconducting magnetic energy storage and fault current limitation system.
