Embodiment
[0037]like figure 2 As shown, the equipment of the existing smart substation is basically divided into station control layer equipment, bay layer equipment and process layer equipment. The station control layer device and the bay layer device are connected through the station control layer network, and the bay layer device and the process layer device are connected through the process layer network. Substation monitoring equipment, dispatch centers at all levels, information integration platforms, GPS hosts, etc. all belong to the station control layer equipment; bay layer equipment includes protection measurement and control devices, network analyzers and wave recorders, etc.; process layer equipment is the merged unit intelligent terminal Integrated devices, etc.
[0038] The method of the present invention uses the wavelength division multiplexing form of single-fiber bidirectional transmission, through the process layer multi-wavelength optical switch, the GOOSE network,...
