Embodiment 1

[0098] Embodiment 1, the user's residential building to be planned is a tower.

[0099] Specifically, the power distribution structure of the above-mentioned towers is usually: single (double) strong electric well, multi-stage power supply mode, and generally there is one (or two double strong electric wells) low-voltage building power distribution room in the basement of the building, and the building power distribution room Through the strong electric shaft, the multi-section T-connection power supply method is used to supply power to the building. The main electrical nodes and equipment include: community power distribution room, building power distribution cabinet, floor distribution box and household distribution box, etc.

Embodiment 2

[0100] Embodiment 2, the user's residential building to be planned is a villa.

[0101] Specifically, due to the large area of ​​the villa area and many and scattered load points, its power distribution structure usually centers on the power distribution room of the community, and adopts a radial power distribution method to the surrounding user residences. Its main electrical nodes and equipment include: community power distribution room, household power distribution box.

Embodiment 3

[0102] Embodiment 3, the user's residential building to be planned is a rural area.

[0103] Specifically, the residential buildings in rural areas are usually connected to the concentrated residential areas in various villages by means of overhead cables. The main electrical nodes and electrical equipment include: distribution boxes in villages and distribution boxes in concentrated residential areas.

[0104] S202. Obtain a path planning scheme from the central office OLT to each optical splitter OBD in the power fiber-to-the-home network generated according to the power distribution structure information; the path planning scheme includes: the number and location of OBDs;

[0105] It should be noted that, for the three different embodiments listed in S201, the following describes how to generate a path planning scheme from the central office OLT to each optical splitter OBD in the power fiber-to-the-home network according to the above-mentioned embodiments according to the ...

Abstract

Embodiments of the present invention provide a method for determining a power fiber-to-home network planning scheme based on a plurality of scenarios. The method comprises the following steps of: by combining the power distribution structure information of different buildings under various scenes, targeted optical distribution network ODN line path design is carried out; genetic algorithm is usedto solve the cost objective function of ONU packet-connected beam splitter OBD according to the constraint parameters;by analyzing the optical channel link attenuation value of the planning network, the power fiber-to-home network planning of different buildings can be obtained, which is in accordance with the practical application requirements. It can be seen that the electric power fiber-to-homenetwork planning scheme designed for various scenes not only meets the planning requirements of different regions and environments, but also ensures the reliability of user services and reduces the laying cost of network lines as much as possible by applying the embodiment of the invention.

Description

technical field [0001] The invention relates to the technical fields of power grid and communication, in particular to a method for determining a planning scheme of an electric fiber-to-the-home network based on various scenarios. Background technique [0002] PFTTH (Power Fiber to the Home) refers to the use of cables such as OPLC (Optical Fiber Composite Low-voltage Cable, optical fiber composite low-voltage cable) in the low-voltage communication access network, and the optical fiber is laid along with the low-voltage cable. , realize meter-to-home distribution with passive optical network technology, and carry smart grid power distribution and consumption links and triple play related services. [0003] PFTTH network structure such as figure 1 As shown, the network structure consists of three parts: OLT (Optical Line Terminal, Optical Line Terminal), ONU (Optical Network Unit, Optical Network Unit) and ODN (Optical distribution node, Optical Distribution Network), where...
