Margin checking system for power communication network

Abstract

The invention, which relates to the operation maintenance field of the communication network, discloses a margin checking system for a power communication network. On the basis of a topological structure of a power optical communication system, an importance weight of a carrier power business is used as an analysis factor and main factors affecting reliability of optical transmission equipment and an optical fiber link are taken into consideration comprehensively; and the communication risk probability existing in the power business is analyzed to realize advanced early warning, automatic route optimization selection is carried out on a business channel with a communication risk, and prevention measures are taken to reduce the risk of interruption of the power business. The system mainly comprises a reliability evaluation model of a communication network and a risk evaluation algorithm of a business path. According to the invention, the scientific and effective analysis means is provided for network usability, so that the communication operation maintenance staff can find the communication network margin accurately; and the practicability is high.

Description

technical field [0001] The invention relates to the field of communication network operation and maintenance, in particular to a power communication network margin checking system. Background technique [0002] With the construction of smart grid and the continuous development of power grid informatization, modern advanced information communication technology is highly integrated with power grid system, and the combination of communication system and power grid system is becoming increasingly close. The high stability of the power system requires a high level of informatization and automation in power generation, transmission, and transformation, all of which are inseparable from the support of advanced power communication systems. Therefore, the reliable operation of the grid system is inseparable from the high reliability of the power communication system. At present, the research on the reliability of power communication networks mainly focuses on the preliminary network...

Problems solved by technology

[0004] 1) The power system lacks a clear definition and quantitative analysis methods for the reliability and failure of the power communication network. It is difficult to solve practical problems in power communication mainly relying on the reliability research methods of the public network; Concentrate on theoretical models and analysis methods, and lack corresponding technical means for quantitative analysis;

[0005] 2) The reliability technical indicators of the power optical communication network are mainly from the perspective of telecommunication services, and the requirements for indicators carried by the communication channels of power services are not fully considered, so that real-time control service systems such as power grid protection and stability require a large number of redundant equipment configurations and communication channels, resulting in a waste of resources and an increase in maintenance costs;

[0006] 3) At present, the reliability of the electric power optical communication network mainly considers the protection and recovery measures to be taken to restore the business in a timely manner after the failure of the communication channel, but there is a lack of effective methods and means for risk monitoring and early warning of communication business path failures
