摘　　要：电阻型超导直流限流器作为故障短路电流的新型抑制设备已被较多学者研究,但尚未有其在多端柔性直流输电系统实际场景中的设计、应用效果和相关影响性分析与研究。论文针对160 kV 1 kA电阻型超导直流限流器在南澳多端柔性直流工程的设计与应用进行了总结,主要包括以下几部分:(1)电阻型超导直流限流器在柔性直流输电系统应用的可行性研究与其对短路电流发展特性的影响分析;(2)超导直流限流器失超态电阻快速计算研究,基于R-Q曲线的在线迭代计算方法;(3)160kV 1 kA电阻型超导直流限流器参数与设备设计方案研究;(4)含电阻型超直流限流器的南澳柔性直流工程控制保护系统架构分析。最后,对加装所研发电阻型超导限流器的南澳柔性直流工程开展了人工短路试验,并通过仿真结果和实测数据验证了以上研究内容的正确性与有效性。As a new type of fault current suppressing device,resistive type superconducting current limiter(R-SFLC)has been studied by many researchers.However,there is no relevant study of R-SFCL on system design,application,and relevant impact analysis in the scenario of multilevel converter-based multi-terminal high voltage DC transmission(MMC-MTDC)system.Accordingly,this paper summarized the design and application of 160 kV 1 kA R-SFCL in the practical Nan’ao MMC-MTDC project,including the following parts:(1)the impact analysis of R-SFCL on DC side short-circuit current suppression in MMC-MTDC system;(2)online iterative calculation method for R-SFCL quenching resistance based on R-Q curve;(3)parameter design and prototype structure development of R-SFCL prototype;(4)system control and protection scheme for Nan’ao MMC-MTDC project with the developed R-SFCL device.Finally,the correctness and effectiveness of the above research and development are verified through the artificial single-pole short-circuit filed test with the developed R-SFCL in the Nan’ao MMC-MTDC project.
