Abstract：The technology of digital substation replaces the traditional electrical cables with fiber to transfer the analog and switching value. The decoupling and concrete cable is substituted with coupling and abstract information flow，which greatly challenges the running，maintaining and dispatching of the digital substation. To overcome this problem， a brand new architecture of information flow intelligent analyzing and visualizing system in the digital substation was proposed. Basing on the distributed information gathering system，the intelligent analyzing and visualizing system supplies the maintainers and dispatchers with all abstracted and analyzed flow information running in the fiber in the form of direct graph. Results show that the system can  decrease the human error on operation and increase the reliability of the digital substation.
