Abstract

Abstract: A healthy process-level network is a necessary precondition to ensure the normal operation and function of a smart substation. Network storm has negative impacts on the information transmission and equipment in the station, consequently harming the normal operation of substation. In this paper, the transmission speeds of GOOSE packets and SV packets in smart substation network are calculated based on their different structures. The mechanism of the network storm is analyzed and the corresponding impact is also estimated. By taking a network storm in a real substation for case study, the network storm was detected by analyzing the packets in the network recorder and checking connections between switches.The solution to network storm is to disconnect the redundant connections and the failed devices. Finally, it is proposed that packages check, VLAN technology and STP protocol are measures against network storm.

Key words: smart substation, process-level network, VLAN, network storm, GOOSE packets, SV packets
