The Analysis and Display Method of Digital Substation Network Based on Business Chains

In this paper, the status of digital substation network monitoring and message analysis is introduced, the procedures and execution process of the typical business chains are analyzed such as control business chain, relay action business chain, measurement business chain, and the analysis and display method of digital substation network based on business chains is proposed. Taking the control business chain as an example, the model mapping method of business chain and the key information points of the protocols are illustrated. The function of the analysis and display method of digital substation network based on business chains is realized via multi-protocols association analysis. The verification instance is presented, the beneficial effects and further improvement of the method are summarized.
