The invention discloses a mechanical fault monitoring method for a photoelectric composite submarine cable, and the method comprises the steps: obtaining the voltage and current of the photoelectric composite submarine cable, and calculating a loss value according to the voltage and current; acquiring temperature data of the photoelectric composite submarine cable; determining a fault evaluation index of the photoelectric composite submarine cable based on the BP neural network; and adjusting the monitoring frequency according to the fault evaluation index, and pre-judging the safety state of the submarine cable. Through real-time detection and state pre-judgment of the photoelectric composite submarine cable, pre-judgment and timely early warning of potential safety hazards are realized, and safe and stable operation of the submarine cable is effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of submarine cable monitoring, in particular to a mechanical fault monitoring method of a photoelectric composite submarine cable. Background technique [0002] With the development and utilization of marine resources, people pay more and more attention to marine rights and interests, and submarine power cables have been widely used. Submarine cables are an important part of the construction of cross-sea networking projects, and play an important role in realizing the internationalization of power grids and the interconnection of regional power grids. With the development of the marine economy, the application of submarine cables in our country is also increasing. Submarine cable communication is widely used because of its long transmission distance, large capacity, low loss, high reliability, and good anti-interference and confidentiality. Submarine scientific observation, military, coastal defense communi...
