Automatic Identification Method of Secondary Device Port in Intelligent Substation

In order to improve the management and control ability of the secondary system in intelligent substation, an automatic identification method of secondary device in intelligent substation based on network message parsing is proposed. The network communication mode of process layer is analyzed briefly from aspects of the Ethernet networking technology of process layer and the IEC61850 based communication protocol. The process and method of automatic generating lED device port table which carries network topology information and connection of device by the SCD file parsing and the statistic of switch port table is studied. The study has important significance to technologies of the management and control of network topology of process layer and the plug and play of secondary device, which provides new approach for the management and control of secondary system network in intelligent substation.
