摘要：
The extensive application of GOOSE and sample data transmission in digital substations requires the high performance of communication networks. Traditional shared multicast communication mode is not suitable for digital substations because it may aggravate the network conflict and increase the receiving error. VLAN partition technology supporting IEEE802.1Q and GMRP networking technology are discussed and it is pointed out that both, the former together with the isolated broadcast domain method and the latter with the dynamic multicast registered technology, can be used in theory to avoid the overloaded multicast flow of digital substation transmission, while the latter is better because of its simple project implementation & maintenance and precise flow control.
