Switch Technology in Intelligent Substation

Abstract:

As the technology of intelligent substation is developed gradually, the significance of he Ethernet switch in the substation is obvious increasingly.Firstly, the learning and transmitting principle of Ethernet frame are introduced, then the network program of secondary system using the switch in the hierarchial structure is described. And then a detailed analysis of the VLAN, QoS, mirror and ring network is given, also the various technical application scheme are provided according to a variety of IED features and data flow characteristics. On the basis of the different business needs and different message types, the reasonable design of network topology and the flexible use of these switching technology , can support security, stability, reliable transmission of communication message in intelligent substation , therefore the whole substation becomes more strong.
