In recent years

with the rapid development of smart substation

the communication network in substation is becoming more and more important. It is necessary to study a better analysis and display method to monitor the communication network and operation of business in substation. Based on the status quo of communication network status monitoring and message analysis technology of smart substation

the process and execution process of typical business chains

such as remote control business chain

relay protection action business chain and remote measurement business chain

are analyzed in detail. This paper presents an analysis and display method of network monitoring business chain in smart substation. Taking remote control business chain as an example

it illustrates the model mapping method of each link of business chain and the correlation method of key information points of each protocol

and then realizes the analysis and display method of network monitoring business chain.
