This application discloses a method, apparatus, electronic device, and medium for
processing protection action defect data. The method includes: identifying and reading protection action defect data from
relay protection equipment to obtain protection action information and protection action details; determining the basic equipment information corresponding to the protection action information, and determining the equipment fault status of each substation based on the protection action information and the basic equipment information; statistically analyzing the protection action information to determine the protection
action status of each substation, and using the protection action details, equipment fault status, and protection
action status as the
processing results of the protection action defect data. The technical solution of this application embodiment can achieve automatic reporting of protection action information, and at the same time, can ensure the comprehensiveness of the
processing results of protection action defect data, providing strong support for power
system fault analysis, equipment maintenance, and safety management.
