High-voltage power cable on-line monitoring system and method

The invention relates to a high-voltage power cable on-line monitoring system and method, and the system obtains cable monitoring parameters collected by each sensor through a data obtaining module, facilitates the obtaining of various monitoring data of a high-voltage cable, and guarantees the accuracy of each monitoring data. The data screening module performs validity analysis and redundant data filtering on the cable monitoring parameters to obtain to-be-identified data, the validity analysis comprises error data filtering processing, and the redundant data filtering comprises identified redundant data filtering processing, so that the redundant data can be reduced, and the data processing efficiency is further improved; the data identification module identifies the to-be-identified data through the set fault identification model so as to determine the high-voltage cable monitoring result, and the to-be-identified data comprises at least two types, thereby facilitating the improvement of the fault predict
