Optical fiber composite connecting system for digital transformer substation

Abstract

The invention discloses an optical fiber composite connecting system for a digital transformer substation. The optical fiber composite connecting system includes that: a relay room which is at least installed with a switch is connected to a power distribution device site by an optical fiber, the optical fibers in the relay room are respectively aggregated into at least two optical fibers by a relay ODF aggregating device according to the dual-network principle, and the optical fibers are laid along cable channels locating in different fireproof areas through at least two different routes according to different paths or the same path; the optical fibers reach the power distribution device site and are connected to the ODF aggregating device arranged at the power distribution device site ina centralized manner after reaching the power distribution device site, and is then transferred to other on-site devices by the ODF aggregating device. In the system, a moderately-centralized scheme is considered, and the configuration of the in-station networking switch is optimized as well as integrated, so as to avoid the bottleneck effect caused by excessive centralization. In addition, the optical fiber connecting system also has the following characteristics: on the basis of centralization, a complete dual scheme is considered for the route laying of the optical fibers and the connecting manner of the optical fibers with an ODF, thereby greatly improving the reliability of network communication of the entire transformer substation.

Description

technical field [0001] The invention is a new optical cable composite connection system, which belongs to the network communication system of the digital substation, and provides an efficient solution for the network communication optical cable connection of the digital substation. technical background [0002] The digital substation takes the primary and secondary equipment of the substation as the digital object, and based on the high-speed network communication platform, realizes information sharing and interoperability through the standardization of digital information, and realizes relay protection and data management based on network data. It is a substation that meets the requirements of modern substation construction such as safety, stability, and construction economy. [0003] With the rapid and continuous development of power loads, the gradual formation of large-capacity and super-large system grids, and the increasing requirements for grid security, stability, re...

AI Technical Summary

Problems solved by technology

[0007] 1. Replace traditional cables with a large number of optical cables, and the advantages of digital substations cannot be reflected

[0008] 2. Due to the large number of optical cables, it is impossible to make overall arrangements for the laying routes of the optical cables, resulting in redundant network connection optical cables using the same route during laying, thereby reducing the reliability of network communication

[0009] 3. A large number of optical cables are scattered and laid, requiring a large number of cable trenches, and the amount of civil engineering and optical cable laying work is relatively large

[0010] 4. There are too many optical cables laid in the cable trench, which requires high safety measures such as fire prevention

[0011] 5. The physical structure of the network is complex, and the workload of operation and maintenance is huge, which is not conducive to rapid troubleshooting
