Problems solved by technology

At present, most of the business paths of the power optical communication network are divided into domains and managed autonomously, and the influence of the power grid control system on the communication system is not considered. There is often a lack of effective monitoring and real-time communication faults for the real-time operation status of cross-layer and cross-domain communication business paths. Early warning, especially for cross-layer and cross-domain communication service paths under multiple fault conditions, there may be incomplete collection of fault information, network bandwidth resources cannot be uniformly scheduled, and important services cannot be effectively restored and protected

Abstract

The invention discloses a communication safety guard model for an electric power optical transmission network and a control method for said model. The communication safety guard model includes a wide area information collecting model, a communication network reliability evaluation model, a communication fault analysis specialist knowledge base, a communication risk monitoring and pre-warning model and a plurality of communication safety guard lines. By adopting the wide area information collecting model for collecting topological information, link information and alarm information of the electric power optical transmission network in real time, by adopting the communication risk monitoring and pre-warning model and a decision control model for performing communication network reliability and fault positioning analysis and generating intelligent coordination processing strategy and by employing overall resource scheduling and the communication safety guard lines for cooperatively processing and timely eliminating communication faults, service restoration is realized. The invention can solve problems of coordination processing of multiple faults of a complicated transmission network and quick restoration of service paths in a trans-region large power grid interconnection background.

Description

technical field [0001] The invention relates to a defense model and a control method thereof in the technical field of power system communication, in particular to a communication security defense model oriented to an electric power optical transmission network and a control method thereof. Background technique [0002] The characteristics of power control service transmission are mainly low bandwidth requirements and high real-time requirements. At present, power control services are mainly carried on SDH optical fiber networks, and the protection methods are mainly dual-fiber protection and SDH ring network protection. Due to the bandwidth requirements of real-time power control services Not high, mainly through 2M channels to transmit information. Power control services mainly include protection, stability, telecontrol and other control services. Different power control services have different transmission methods and real-time requirements. For the protection business, ...
