Abstract

Fault Current Limiters (FCLs) are crucial for curtailing short-circuit currents in power systems. Their integration, however, profoundly influences the Transient Recovery Voltage (TRV) and Rate of Rise of Recovery Voltage (RRRV) across Circuit Breakers (CBs), directly affecting their fault interruption performance. This paper presents a comprehensive investigation into the theoretical implications of Inductive FCL (IFCL) on both RRRV and TRV using an improved model that more precisely captures its inherent distributed capacitance characteristics. The investigation further extends to comprehensive simulation analyses of both RRRV and TRV, examining terminal faults and Short-Line Faults (SLFs) under diverse system arrangements, including IFCL connections on both source and load sides of the CB, and varying Current Limiting Factors (CLFs). Simulations conducted on a 20-kV distribution feeder and an IFCL model closely resembling the South Korean hybrid FCL under three-phase faults identify the most severe transient conditions affecting the CB. The findings provide valuable guidance for the robust design and strategic implementation of IFCLs, ensuring dependable CB operation and effective fault current breaking.

电感式FCL对断路器RRRV和TRV特性影响的综合理论与仿真分析

故障限流器（FCLs）在电力系统中起着抑制短路电流的重要作用。而它们的集成会深刻影响断路器间的暂态恢复电压（TRV）和恢复电压上升速率（RRRV），直接影响断路器的故障中断性能。本文采用改进的模型，更精确地捕捉其固有的分布电容特性，全面研究了电感式FCL （IFCL）对RRRV和TRV的理论含义。研究进一步扩展到RRRV和TRV的综合模拟分析，检查不同系统安排下的终端故障和短路故障（slf），包括CB源侧和负载侧的IFCL连接，以及不同的限流因子（clf）。在20 kv配电馈线和与韩国混合FCL非常相似的三相故障下的IFCL模型上进行了模拟，确定了影响CB的最严重暂态条件。研究结果为ifcl的稳健设计和战略实施提供了有价值的指导，确保可靠的断路器运行和有效的故障电流断开。
