Failure analysis method and device based on power communication network

Abstract

The invention provides a failure analysis method and device based on a power communication network. The method comprises the following steps: acquiring history data of failures to be analyzed in the power communication network, and acquiring a failure cause type set corresponding to generated failures, wherein each cause type comprises at least one cause factor; calculating cause probabilities corresponding to the cause factors in the cause types, acquiring weights corresponding to the cause factors according to the probabilities, and acquiring failure probabilities corresponding to the cause types according to the acquired weights corresponding to the cause factors; calculating the probabilities of the failures to be analyzed according to the failure probabilities corresponding to the cause types; and if the probabilities of the failures to be analyzed are greater than a first preset threshold, performing troubleshooting in sequence from large to small according to the failure probabilities corresponding to the cause types and the weights corresponding the cause factors in the cause types.

Description

technical field [0001] The invention relates to electric power communication network technology, in particular to a fault analysis method and device based on electric power communication network. Background technique [0002] At present, the power communication network is directly related to the security of the power grid and the reliability of power supply. Therefore, it is particularly important to ensure the safety of the power communication network. With the vigorous development of the power communication network, the structure of the power communication network is becoming more and more complex, and the environment in which it is located is also becoming more and more diverse. Therefore, there are more and more possible faults in the power communication network. [0003] Specifically, in the power communication network, its main components, such as synchronous digital hierarchy (Synchronous Digital Hierarchy, referred to as SDH) equipment, optical fibers, interfaces, e...

[0004] However, in the prior art, the probabilities of failures under different inducements are generally directly given manually, which is highly subjective. Therefore, manual methods cannot effectively guide the operation and maintenance of the power communication network and avoid failures in advance. occur
