As the process layer equipment is added in smart substations,changes are also undergoing in the corresponding network configuration.By summarizing the network configuration and information flow diagram of all intervals of 220 kV smart substations in conjunction with its application in the anomalies of a certain smart substation,a method for processing the network information flow of the smart substation is obtained,which offers reference for onsite solutions to anomalies such as GOOSE and SV disconnections.
