Research on Operation and Maintenance of Process Layer Network Switch Based on Node Importance
Intelligent substation relies on a large number of switching unit networks to realize information interaction.When the switch fails,the information interaction path will be interrupted,resulting in the functional failure of protection devices,intelligent terminals,measurement and control devices and other equipment.This paper analyzes the network topology of typical intelligent substation and the characteristics of process layer network,analyzes the importance of process layer network structure switch by using the node importance method,and puts forward targeted operation and maintenance measures and suggestions according to the analysis results and combined with the field operation.
