Embodiment 1

[0014] Such as figure 1 As shown, this embodiment includes: SCD import module, model analysis module, graph-to-model mapping module, network communication module, and visual display module. Among them: SCD import module imports substation SCD model via HMI, supplementing process layer switches, optical cables, and connection plates After the model is waited for, it is output to the model analysis module; the model analysis module parses the static model of the SCD file to obtain the association relationship between the secondary virtual circuit and the physical connection medium and the association relationship between the logical link and the functional circuit based on the SCL tag search technology, and Output to graphic-model mapping module; the graphic-model mapping module adopts graphic-model integration technology to generate basic graphic elements according to the correspondence between the physical connection optical cable and the communication link and between the commun...

Abstract

The invention discloses an online monitoring system for a modeling based on a physical communication medium of a process level. The online monitoring system comprises an SCD (Security Coding Device) import module, a model analysis module, a graphics and model mapping module, a network communication module and a graph display module, wherein the defects of an IEC 61850 standard model can be supplemented by modeling the physical communication medium (a switchboard, an optical cable, a connecting pressing plate, etc.) of the process level, and a process level switchboard, a connecting optical cable, a pressing plate and other models can be improved. By adopting a graphics and model mapping technology on this basis, the visual online monitoring of a second system can be realized, the application of 'graphics are fit well with the actual situation' of the secondary system based on the model can be realized, the operation and maintenance object can be ensured to have model characteristics, the observability and controllability of the secondary system of an intelligent substation can be improved, and a good foundation can be laid for the expansion of all high application of the intelligent power grid.

Description

Technical field [0001] The invention relates to a power grid secondary system control technology in the field of power systems, in particular to an online monitoring system based on process layer physical communication medium modeling. Background technique [0002] At present, the intelligent substation information communication mechanism that is vigorously promoted in China is based on the IEC61850 standard. The IEC61850 standard proposes a "three-layer two-network" architecture system, in which the process layer uses SV and GOOSE messages, optical cables are used instead of cables, and SV and GOOSE "data packets" "To realize the information association between IEDs, the IEC61850 standard only emphasizes the connection relationship of the communication link, which weakens the communication medium of the network equipment and the process layer. In the IEC61850 standard, there is no description of models such as process layer switches, connecting optical cables, connecting pressur...
