Problems solved by technology

[0008] 5. In view of the obvious differences in the network requirements of SMV, GOOSE and IEC61588 messages, under the dual-network architecture, the cost of communication equipment and optical cables increases greatly, and there are many network interfaces for power equipment
However, with the deepening of the research on IEC61588, such messages require the participation of the CPU, so that the IEC61588 messages may pass through the VLAN, resulting in isolation failure. How to ensure the safe isolation of data transmission and network security issues are still not well resolved solve

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,...

Abstract

The present invention relates to power intelligent transformer station process level communication network technology, and specifically relates to an intelligent transformer station process level optical fiber multi-wavelength isolated communication networking method. The method adopts wavelength division multiplexing with single fiber bi-directional transmission; a low loss window of the optical fiber is divided into three or more bi-directional transmission channels according to different frequencies or wavelengths of optical carrier signals of different channels; the GOOSE network, SMV network, and IEC61588 network of the process level are separately supported by carriers of different wavelengths via a process level major multi-wavelength switch, and are multiplexed and decomposed by a wavelength division multiplexer to form one physical network. The method enables the GOOSE network, SMV network, and IEC61588 network in the process level to share the same network and perform transmission in an isolated manner, thereby lowering the construction cost of the intelligent transformer station, and lowering the maintenance cost and construction difficulties.

Description

technical field [0001] The invention relates to a process layer communication network technology of an electric power intelligent substation, in particular to a process layer optical fiber multi-wavelength isolation communication networking method of an intelligent substation. Background technique [0002] At present, the process layer of smart substation proposes the requirement of "three-network integration", also known as "three-network integration" (that is, GOOSE network, SMV network, and IEC61588 network), that is, to integrate the three networks of the process layer in a logical or physical form. A smart substation network architecture that synthesizes a network. The smart substation process layer networking scheme and its security are currently the "hot spots" in the research of smart substation communication networks. [0003] In the existing substations, most of the networking methods of the process layer are A and B dual-network networking methods and hybrid netw...
