Abstract

The invention provides an electrical communication system fault diagnosis method and device. The method comprises the steps of obtaining basic fault information of a target fault; obtaining a prestored electrical communication system fault case library, wherein the electrical communication system fault case library stores basic fault information, fault phenomenon description, fault reason deduction and diagnosis strategies of a plurality of fault cases; comparing the basic fault information of the target fault with basic fault information of each fault case in the electrical communication system fault case library, and determining the fault case with the target fault similarity exceeding the first preset similarity threshold value as a typical fault case from the electrical communication system fault case library; according to actual information of on-site faults, optimizing the typical fault case, and determining the optimized fault diagnosis case of the target fault; according to theoptimized fault diagnosis case, performing fault diagnosis on the electrical communication system, and the faults of the electrical communication system can be accurately diagnosed in real time.

Description

technical field [0001] The invention belongs to the technical field of electric power information, and in particular relates to a fault diagnosis method and device for a power communication system. Background technique [0002] The power communication system is an important part of the smart grid and an important basis for ensuring the production, operation, management and power supply services of the power grid. The power communication system is an important support network of the power system. With the rapid development of UHV and smart grid, in order to ensure the safe operation of power production business, higher requirements are put forward for the reliability and stability of the power communication system. Timely diagnosis The key content of power communication dispatching and operation work for power communication system faults. [0003] At present, the traditional fault diagnosis methods for power communication systems mainly rely on the dispatcher’s experience an...
