Problems solved by technology

However, after a large-scale failure of the power communication network in a natural disaster or other event, it is often accompanied by the destruction of a large area of ​​communication lines and infrastructure, which can easily lead to the loss of contact between the substations and the dispatching center. At this time, it is necessary to rely on the dispatching center to restore Compromised networks are often not viable

Embodiment Construction

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0080] The purpose of the present invention is to provide a recovery method and system for a faulty link of a power communication network. When a large-scale fault occurs in a power communication network and recovery resources are limited, an optimal link is selected by calculating the cost-effectiveness value of the distance resources of each faulty link. The combination of faulty links restores the power communication network, so that the number of businesses...

Abstract

The invention discloses a recovery method and system of electric power communication network fault link. The recovery method and system are advantageous in that when the electric power communication network has large-scale fault and the recovery resource is limited, the fault link of the electric power communication network can be recovered based on the fault link distance resource, and thereby itcan be guaranteed that the fault link with high cost performance can be recovered at first, and the electric power communication network after the fault can bear more electric power business, and thewhole electric power communication network recovery process can be conducted in a targeted manner, and the safe and stable operation of the electric power communication network can be ensured.

Description

technical field [0001] The invention relates to the technical field of power system communication, in particular to a method and system for recovering a faulty link of a power communication network. Background technique [0002] As the size and complexity of power communication networks continue to increase, so does the likelihood of large-scale network disruptions. The recovery work after a large-scale network destruction requires a lot of manpower, material and financial resources, and the recovery resources are often not fully provided at one time, resulting in the failure of the network recovery work to be carried out in an all-round way, so that the recovery work cannot be carried out in a targeted manner. [0003] The current power communication network has achieved certain results in the repair of large-scale failures, but there are still some problems. For example, in natural disasters, the protection of the power dispatch automation communication network is mainly ...
