A Correlation Analysis Method for Power Communication Network Fault Incentives and Service Impacts

Abstract

The invention discloses a correlation analysis method for the cause of a power communication network failure and service impact, and belongs to the field of power communication. The method includes the following steps: Aiming at the lack of quantification of the probability of occurrence of the cause of the power communication network before, based on historical data and the current state, an effective method for quantifying the probability of failure caused by the cause of different factors is proposed; based on the quantification method of the failure probability, from the business From the perspective of active and standby routing, a quantification method of business impact is proposed to complete the mapping from the quantification method of the failure probability caused by the cause to the business impact degree; in order to make the model conform to the engineering application, a business impact-oriented business routing is proposed for the change of the business impact degree Switch method. The present invention quantifies the failure probability caused by the incentives that may cause the failure of the power communication network. Based on the quantification method, a dynamic service routing switching method is proposed according to the failure process to effectively guide actual engineering operation and maintenance 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...

Problems solved by technology

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
