Abstract: Without additional cost on new smart substation switches and interference in data service communication, a management technology GMT (GOOSE Management Technology) is proposed for solving generic object oriented substation events(GOOSE) of smart intelligent substation switches，which can realize the centralized (batch) configuration of switches, reduce the number of IP addresses, save the effort in deployment, operation and inspection, collect diagnostic information with one click, replace switch without reconfiguration, upgrade software in batch, and improve management automation for communication equipment. After the introduction of the GMT overall design on a switch, the data channels， the generation of configuration files, and the system architecture of the switch software are analyzed. The system can support the security command line, HTTPS, SNMPv3， IEC 61850 and other syntax formats. The communication protocol of smart substation switch clustering management should be stable, reliable, simple, efficient, and easily extensible. The state machine transition of the main switch and the member switches is introduced. The application of GOOSE management technology on switches is versified on star topology in the laboratory. Comprehensive and quick fault positioning and clearance is supported by efficient management and maintenance on communication equipment with GMT technology. GMT can greatly reduce the workload of related operators and improve the efficiency of communication equipment management.
