A SYSTEM AND METHOD FOR TRANSMITTING INFORMATION ACROSS A SUBSTATION AUTOMATION NETWORK

摘要

A system and method for sharing authentication information and authorization information across a Substation Automation Network have been disclosed. The system and method enable the Substation Automation Network to function independent of the availability of a CAMS which typically administers the process of sharing of authentication information and authorization information across the Substation Automation Network. The system and method propose segregating the IEDs of the Substation Automation Network into different groups, and dynamically enabling at least one IED to transmit the authentication information and authorization information to the other IEDs in the respective groups, at predetermined time intervals, thereby ensuring that the Substation Automation Network is operable independent of the CAMS.
