ABSTRACT

This study presents a modified solid-state fault current limiter (SSFCL) based on AC/DC reactor, which limits both transient and steady-state fault currents under fault condition. It includes two diodes and one insulated-gate bipolar transistor (IGBT) switch. The number of semiconductor switches in the proposed AC/DC reactor SSFCL is a quarter and half of the semiconductor switches employed in the fully-controlled and conventional AC/DC reactor BFCL, respectively. It offers lower cost, simple structure and more reliability comparing with the conventional models. Also, the inductance and current rating of AC/DC reactor used in the proposed AC/DC reactor SSFCL is equal to the fully-controlled and conventional AC/DC reactor BFCL. The power circuit and principle operation of the modified AC/DC reactor SSFCL are presented. Then, the analysis of normal and fault operating conditions of the proposed AC/DC reactor SSFCL is provided. Finally, the performance of the proposed AC/DC SSFCL is verified by both PSCAD/EMTDC simulation and experimental results.

基于交直流电抗器的改进型固态故障限流器

摘要

本研究提出了一种基于 AC/DC 电抗器的改进型固态故障电流限制器 (SSFCL),可在故障条件下限制瞬态和稳态故障电流。它包括两个二极管和一个绝缘栅双极晶体管 (IGBT) 开关。所提出的 AC/DC 电抗器 SSFCL 中的半导体开关数量分别是全控和常规 AC/DC 电抗器 BFCL 中使用的半导体开关的四分之一和一半。与传统机型相比,成本更低、结构简单、可靠性更高。此外,建议的 AC/DC 电抗器 SSFCL 中使用的 AC/DC 电抗器的电感和电流额定值等于全控和传统的 AC/DC 电抗器 BFCL。介绍了改进型交直流电抗器 SSFCL 的电源电路和工作原理。然后,提供了对所提出的交流/直流电抗器 SSFCL 的正常和故障运行条件的分析。最后,通过 PSCAD/EMTDC 仿真和实验结果验证了所提出的 AC/DC SSFCL 的性能。
