Research on Multicast Flooding Suppression in Smart Substation

Abstract:

The existence of a large number of multicast flooding data in the process level of smart substation,causes serious influence on the real-time performance and reliability of network.Through the exchange principle of Ethernet,the forwarding process of second-layer multicast in network is introduced. Combined with the application in intelligent substation and some experimental data, through in-depth analysis of the 802.1Q VLAN isolating broadcast domain,setting static multicast to change the static MAC address table ,and GMRP to change the multicast information on Ethernet switch through the interactive protocol data, the multicast flooding suppression method is illustrated. And based on the practical engineering situation, the three kinds of methods are compared from the characteristics of debugging operation and maintenance convenience and reliability of intelligent equipment,then the technology route recommendation is given.
