Abstract

DC fault current limiters (FCLs) are of great significance to the safe and stable operation of DC distribution systems. Among the various FCLs, inductor-based FCLs play an important role. However, the issue of inductor saturation generally exists, which causes limitations in practical engineering applications. A novel LC-resonance-based FCL is proposed in this paper, which can suppress the inductor-saturation effect and create a natural zero-cross current for enhancing performance. In addition, it can cooperate with the AC circuit breaker (ACCB) to quickly cut off faults. A theoretical analysis and the parameter design of the proposed FCL are presented. Finally, a scaled-down experiment test platform is built, and experiment tests and simulation case studies are carried out to verify the working principle and superiorities of the proposed FCL.

新型串联 LC 谐振直流故障电流限制器
直流故障限流器(FCL)对直流配电系统的安全稳定运行具有重要意义。在各种 FCL 中,基于电感器的 FCL 发挥着重要作用。然而,电感器普遍存在饱和问题,这给实际工程应用带来了限制。本文提出了一种新颖的基于 LC 共振的 FCL,它可以抑制电感饱和效应,产生自然的零交叉电流,从而提高性能。此外,它还能与交流断路器(ACCB)配合,快速切断故障。本文介绍了拟议 FCL 的理论分析和参数设计。最后,建立了一个按比例缩小的实验测试平台,并进行了实验测试和仿真案例研究,以验证所提出的 FCL 的工作原理和优越性。
