摘　　要：基于饱和铁心型高温超导故障限流器拓扑,提出了一种适用于中高压电网的磁控开关型故障限流器结构。通过工作原理分析,论证了此拓扑结构的可行性,建立了限流器的数学模型和简化电路模型,推导出这种限流器系统的设计公式,并在此基础上研制了一台220V/50A限流器模型机。试验结果表明,该故障限流器具有快速、有效的故障电流限制作用,且具有结构简单可靠,运行控制灵活的特点。Based on the topology of the saturated iron core superconducting fault current limiter, a novel magnetic-controlled switcher type fault current limiter is proposed for medium and high voltage electric network. The operation principle analysis testifies the validity of the topology; then the mathematical model and simplified circuit model of the FCL are analyzed, and the expressions of the parameter design of this system are deducted. Upon these expressions, a 220V/50A limiter is built. The test results show that the magnetic-controlled switcher type fault current limiter can limit the fault current swiftly and effectively, and has the advantages of simple and reliable structure and flexible control strategy.
