Conventional methods use manual checking for point matching to ensure data correctness for the connection of a substation into its main scheduling station,which is inadequate for centralized control stations since they usually need to collect a large amount of data from substations.In view of this,the present work studied and proposed dataset data num-bering rule and data transmission data mapping scheme based on general service protocol and 61850 model,which conse-quently achieved point-matching-free rapid access of substation to centralized control station with reliable data accuracy.
