Detailed Description
The invention is further described with reference to the following figures and examples.
It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the invention.

Example one
Referring to fig. 1, the method for optimizing the double uplink optical path for adjusting the ground power OTN optical transmission system in the embodiment includes:
step 1: acquiring a provincial region communication network optical cable system diagram, and searching a transformer substation C with the A-site distance not exceeding a preset distance; and the A ground-tone double light path is connected with a transformer substation B with the same voltage as the transformer substation C in a single-point mode.
In the specific implementation process, as shown in fig. 2, a 500kV substation is taken as an example:
and finding out a city company with the double-upper-link physical condition of the OTN optical transmission system, recording the city company as an A local tone, so that the A local tone has the condition of double-point access transformation, and recording a 500kV transformer substation connected with the A local tone in a single-point mode as a B transformer substation. According to the provincial region communication network optical cable system diagram, finding another 500kV transformer substation station with a preset distance (for example, less than 100km) adjusted to the A region, and recording as a C transformer substation. The provincial region communication network optical cable system map refers to a map matched with the provincial region communication network optical cable system.
For example:
the 26-local tone of a city company with the double-upper-link physical condition of the OTN optical transmission system is found out, the 26-local tone has the condition of double-point access transformation along with the commissioning of a new 500kV transformer substation and the optimization of an optical cable net rack, and the 500kV transformer substation connected with the double optical paths and the single point is marked as a 7-transformer substation. And finding another 500kV transformer substation station close to 26-ground from the latest 'provincial region communication network optical cable system diagram', and recording the station as a 70-transformer substation.
Step 2: and obtaining a city-level regional communication network optical cable system diagram, searching physical routing nodes of optical paths from A local tone to the transformer substation C and the transformer substation B and vacant optical cable fiber core resources of the city lines, and determining the activeness of the optical paths.
In specific implementation, a physical routing node of a local tone reaching a C transformer substation and a vacant optical cable fiber core resource of a local line are found from a city level regional communication network optical cable system diagram of a corresponding local company. And synthesizing the existing network management optical path service routing mode, if the original A-site-to-province (standby) modulation service main optical path route passes through the C transformer substation, adjusting the A-site-to-B transformer substation main optical path to be the A-site-to-C transformer substation optical path, and the A-site-to-B transformer substation standby optical path is reserved.
The optimal physical routing mode of the A-site to C-site substation is determined according to the following four principles, 1, uniformly selecting the station distance; 2. selecting a light path with good optical cable performance and sufficient fiber core resources; 3. using an OPGW optical cable to bear an optical path as much as possible; 4. the topological structure is optimized, and the light path jump points are reduced.
For example:
from the city level regional communication network optical cable system diagram of the corresponding city company, physical routing nodes of which the 26-local tone reaches 70-transformer substation and vacant optical cable fiber core resources of the city line are found. And determining the optimal physical routing mode for adjusting 26-ground to 7-transformer substation primary or standby optical path and 26-ground to 70-transformer substation by integrating the existing network management optical path service routing mode.
If the route of the adjusted light path from the place A to the substation B is the same as that of the existing light path service, because the services are protected by the SNCP, the double-up optimized maintenance of the city company can be completed without influencing the services. If the mode of adjusting the light path from the A place to the B substation is opposite to the existing light path service routing mode, the Och light path needs to be made again, and the service carried on the OTN light path is interrupted in a short time. During maintenance, light paths with different wavelengths are interrupted in turn, and the influence on the service is reduced to the minimum.
For example:
and compiling a maintenance ticket and formulating a service cutting and connecting scheme. If the route of the adjusted 26-ground to 7-transformer substation optical path is the same as that of the existing optical path service, because the services are protected by the optical path SNCP, the double-up optimized maintenance of the local company can be completed without influencing the services. If the mode of the adjusted 26-ground to 7-substation optical path is opposite to the existing optical path service routing mode, the Och optical path needs to be made again, so that the service carried on the OTN optical path is interrupted in a short time. During maintenance, light paths with different wavelengths are interrupted in turn, and the influence on the service is reduced to the minimum.
And step 3: and receiving a maintenance ticket and a service cutting scheme, and issuing instructions for maintaining and cutting the light path from the A-site to the transformer substation C and the transformer substation B, so that the light path is opened to have physical routing and network routing conditions.
And (3) enabling a light path constructor to reach a C substation, installing and debugging a corresponding optical layer subframe of the OTN system and a required dispersion module, and accessing equipment into the optical fiber distribution cabinet. And completing optical distribution fiber jumping at a routing site needing to adjust tail fiber connection. So that the optical path is opened and has physical routing conditions.
For example: and (4) enabling construction personnel to reach a 70-transformer substation, installing and debugging a corresponding optical layer subframe of the OTN system and a required dispersion module, and accessing equipment into the optical fiber distribution cabinet. And completing optical distribution fiber jumping at a routing site needing to adjust tail fiber connection. So that the optical path is opened and has physical routing conditions.
The network management side finishes network element uploading, signal flow graph connection between the board cards in the subframe and logical fiber connection between two optical network elements. The optical power performance is monitored through the SC2 board, and if the optical power is too high, the optical attenuation needs to be increased. If the optical power is too low, a point with large attenuation needs to be found out, and the tail fiber or the optical core needs to be adjusted. And completing debugging of the new upper subframe equipment, so that the optical path is opened to have network routing conditions.
And 4, step 4: and adjusting the double-uplink light path through service according to the similarity and difference between the light path service routing mode of the local dispatching A and the substation B and the existing light path service routing mode, and realizing the optimization of the double-uplink light path after the adjustment of the rest light paths.
If the route of the adjusted A place to the B substation is the same as the route of the existing light path service, only the light path in one route direction needs to be adjusted, and the other light path is protected from being influenced. The network management needs to cut and connect the light paths one by one in sequence according to the maintenance scheme. And deleting the through service of the transformer substation from the transformer substation B to the transformer substation A of the light path, deleting the original through service of the transformer substation C, and newly building the through service from the transformer substation C to the transformer substation A.
For example:
if the route of the adjusted 26-ground to 7-substation optical path is the same as that of the existing optical path service, only the optical path in one route direction needs to be adjusted, and the other optical path is protected from being influenced. The network management needs to cut and connect the light paths one by one in sequence according to the maintenance scheme. Firstly, deleting the through service of the light path 7-transformer substation to 26-ground adjustment 70-transformer substation, deleting the original through service of the 70-transformer substation, and newly building the through service of the 70-transformer substation to 26-ground adjustment.
If the route of the adjusted optical path from the A place to the B substation is opposite to that of the existing optical path service, the through-service from the B substation to the main and standby optical paths of the A place is required to be deleted first, and then the through-service is made again, which can cause short-time interruption of the service carried on the optical path. The network management needs to cut and connect the light paths one by one in sequence according to the maintenance scheme. The method comprises the steps of deleting a main and standby light path through service from a substation B to a local A with the same wavelength, deleting an original wavelength light path through service from a substation C, newly building a light path through service from the substation B to the local A, and newly building a light path through service from the substation C to the local A.
For example:
if the route of the adjusted 26-ground to 7-substation optical path is opposite to the route of the existing optical path service, the through-service of the main and standby optical paths from the 7-substation to the 26-ground is required to be deleted first, and then the through-service is performed again, which may cause short-time interruption of the service carried on the optical path. The network management needs to cut and connect the light paths one by one in sequence according to the maintenance scheme. The method comprises the steps of deleting a main and standby light path through service from a 7-transformer substation to a 26-ground switch with the same wavelength, deleting a 70-transformer substation original wavelength light path through service, newly building a 7-transformer substation to 26-ground switch light path through service, and newly building a 70-transformer substation to 26-ground switch light path through service.
In specific implementation, the optical power of the optical path of the wavelength channel is adjusted by inquiring the optical power condition of the optical path section by section through the spectral analysis single plate to adjust the adjustable attenuation of the M0V and the WSM9 plate card to adjust the optical power, so that the optical power of each section of the optical path is flat. Finally, the performance condition of the service landing ND2 board card is inquired, the error rate before error correction and the error rate before average error correction of the optical path performance are more than 6, and the error rate after error correction and the error rate after average error correction are 0. The final optical power of the ND2 board is required to satisfy that the absolute value of the difference between the upper threshold value and the optical power is less than 5dB, and the absolute value of the difference between the upper threshold value and the lower threshold value is less than 3 dB. And after one optical path is finished, repeating the sixth step or the seventh step to finish the adjustment of the residual optical path. And observing the performance condition of the adjusted wavelength optical path ND2 board card for 15-30 min. If the performance is stable, the light path adjustment is completed, and constructors can be informed to leave the site.
In the embodiment, by adjusting the physical route of the local company accessing the preset voltage transformer substation, the mode that the original double-light-path single point of the local company is accessed to a transformer substation with the same voltage level to connect the core ring network is changed into the mode that the double-light-path single point is accessed to two transformer substations with the same voltage level, so that the hidden danger of the original single-point access can be effectively solved, the service performance robustness of the provincial electric power OTN optical transmission system is further enhanced, and the normal and stable operation of the power grid service is ensured.
