Abstract

The invention provides a method and system for detecting reliability of a submarine power cable. The method for detecting reliability of the submarine power cable comprises the steps of obtain specific fault characteristics of the submarine power cable through analysis of historical fault data of the submarine power cable, carrying out analysis to obtain fault factors of the submarine power cable according to the specific fault characteristics, building a submarine power cable fault tree model, obtaining the corresponding relation between a top event and bottom events in the submarine power cable fault tree model, and carrying out reliability detection according to operation condition parameters of the submarine power cable and the corresponding relation between the top event and the bottom events in the submarine power cable fault tree model. In the whole process of reliability detection, the specific fault characteristics of the submarine power cable are fully taken into consideration, a fault tree analysis method is adopted, it is ensured that the built submarine power cable fault tree model is accurate, and accuracy of reliability detection is ensured.

Description

technical field [0001] The invention relates to the technical field of submarine power cables, in particular to a reliability detection method and system for submarine power cables. Background technique [0002] Submarine power cables are mainly used between land and islands, crossing rivers or harbors, connecting offshore wind farms on land, connecting drilling platforms from land or interconnecting drilling platforms. Under normal circumstances, the use of submarine cables to transmit electric energy is undoubtedly more expensive than overhead cables of the same length, but it is often more economical than using small and isolated power stations for regional power generation, and the application in offshore areas has more benefits. [0003] In order to ensure the normal operation of the power cable, it is usually necessary to periodically check the reliability of the power cable to determine whether the power cable is in good working condition and whether it needs to be re...
