摘　　要：由于500 kV枢纽站数量增多,短路电流水平也随之提高,线路加装限流电抗器是限制短路电流的一种有效措施。以500 kV线路串联电抗器工程为例,分别研究了串联电抗器间隔的构成、编号规则、状态定义、倒闸操作的原则以及串联电抗器运维措施,为今后线路加装串联电抗器装置提供借鉴。Due to the increase in the number of 500 kV hub substations,the degree of short-circuit current has also increased.Installing series reactors on the line is an effective measure to limit short-circuit current.In this paper,the composition,numbering rules,state definition,principles of switching operation,and operation and maintenance measures of series reactor intervals are analyzed,based on the 500 kV line series reactor project.The reference for the application of series reactors in transmission lines are provided.
