An association analysis method for fault inducement and service influence of electric power communication network

Abstract

The invention discloses an association analysis method for fault inducement and service influence of an electric power communication network, belonging to the field of power communication. The methodcomprises the following steps: for the current situation that the inducing probability of electric power communication network is lack of quantification, according to the historical data and current state, the effective quantification method of inducing probability of failure is put forward according to different factors; based on the quantitative method of failure probability, the quantitative method of service impact is proposed from the perspective of primary and backup routing to complete the mapping from the quantitative method of inducement-induced failure probability to the degree of service impact. In order to make the model conform to the engineering application, a traffic routing handoff method based on traffic impact degree is proposed to deal with the change of traffic impact degree. The invention quantifies the failure probability caused by the inducement which may cause the failure of the electric power communication network, and based on the quantization method, puts forward a dynamic service route switching method according to the failure occurrence process, so as to effectively guide the actual engineering operation and risk prevention.

Description

technical field [0001] The invention relates to a correlation analysis method for power communication network fault inducement and service impact, belonging to the field of power communication. Background technique [0002] At present, various key services carried by the power communication network are directly related to the safe operation of the power grid and the reliability of power supply, so it is particularly important to ensure the security of the power communication network. With the vigorous development of the power communication network, especially the smart grid, the structure of the power communication network is becoming more and more complex, and the environment in which it is located is becoming more and more diverse. Therefore, there are more and more possible faults in the power communication network. In the power communication network, its components such as SDH equipment, optical fibers, interfaces, etc. may fail, and the causes of these failures often c...

Then, the relationship between the cause of the failure and the business impact has not been effectively summarized

In technical solution 2, the possible fault causes and impacts of different alarms are analyzed for the relay protection business, focusing on the correlation between alarms and faults, but there is also a lack of correlation analysis between business impacts and incentives

Technical solution 4 analyzes the network risk value that may be caused by different incentives, but the analysis is based on the number of incentives, the quantitative results are not detailed enough, and there is no effective research on the failures that may be directly caused by the incentives and their associated solutions.

Analysis of technical solution 5’s impact on failure causes and business is relatively lacking
