Analysis of a 110 kV Line Protection Abnormal Action for the Instantaneous Disappearance of DC
This paper describes an incident in which the 110 kV line protection behaves abnormally due to the instantaneous open circuit of the battery,despite there being no fault present.By analyzing the specific protection action messages and fault recordings,the cause of the incident is determined,and targeted pre-ventive measures are proposed,which have certain reference significance for the on-site equipment opera-tion and maintenance,as well as engineering design.
