To ensure the stability and reliability of the process level network in smart substation, the network flow must be managed. The characteristic of the smart substation process level network is presented, and kinds of multicast management modes are introduced. The differences among all modes are analyzed, and then it is put forward that static multicast management is the suitable way for process level network at present. In addition, the network storm which may cause catastrophic fault can be prevented by the port input rate limiting. So the combined use of static multicast management and port input rate limiting to manage the network flow conforms to the smart substation development level and the application requirements at present, and its feasibility and validity are proved using practical application instance.
