Shared-network scheme of SMV and GOOSE in smart substation

The network structure of the smart substation in common use was introduced, and the technical problems of the shared-network of sampled measured value (SMV) and generic object oriented substation event (GOOSE) were analyzed, such as the processing ability of network device and the intelligent device, the data real-time property and the network reliability, the effects to the substation in the condition of network fault, etc. On this basis, the feasibility of the shared-network of SMV and GOOSE was discussed, the implement scheme was presented, and eventually the solution of the shared-network of SMV and GOOSE was put forward, which based on the applications of the message priority control, restricting the switch number, virtual local area network (VLAN) and GARP multicast registration protocol (GMRP) classification flow control, flow rate limiting, etc. In the test-bed, the cases of shared-network and separate-network of SMV and GOOSE were compared and analyzed, and the result was valuable for reference.
