摘    要:由于直流输电的特点,换流变压器与交流变压器在构造上有一些不同,再加上直流控制系统对故障的控制和调节作用,导致换流变压器和传统变压器保护存在差异,为此,介绍了天广直流输电工程中换流变压器保护系统的配置和保护范围,并对运行中励磁涌流的影响、交直流保护系统的配合等问题进行了分析,讨论了相关的解决措施,这有助于提高直流输电系统运行的可靠性,可为未来直流输电工程的实施提供参考经验.

关 键 词:直流输电  换流变压器  保护系统  天广直流输电  换流变压器  直流保护系统  系统运行  存在  问题  Project  HVDC  Used  Transformer  Converter  System  实施  解决措施  相关  分析  配合  影响  励磁涌流  保护范围

Abstract:There are some structural differences between converter transformers and AC transformers because of the characteristics of high voltage direct current transmission(HVDC),which,coupled with the fault controlling and adjusting capacity of HVDC control system,lead to the differences between their protective systems.In this paper,the configuration and protective range of the converter transformer protective system used in Tian-Guang HVDC project are introduced,then,the negative influence of magnetizing inrush current in operation and the cooperation of AC and DC protective systems are analyzed,and correlative solutions are discussed.Research carried out in this paper is valuable for development of HVDC projects in the future.
Keywords:high voltage direct current transmission(HVDC)  converter transformer  protective system
