Embodiment Construction

[0037] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] Such as figure 1 As shown, the suspected familial defect analysis model of power transmission and transformation equipment of the present invention collects equipment defects and adopts text mining technology to perform text analysis on power transmission and transformation equipment defect information, and extracts characteristic words of power transmission and transformation equipment defect information, Carry out text similarity calculation and text cohesive hierarchical clustering, analyze the same defect of the same type, same model, and same defect part produced by the same manufacturer, and realize automatic identification of suspected familial defects of power transmission and transformation equipment.

[0039] In order to effectively use this method, it is necessary to ensure that the present invention ha...

Abstract

The invention relates to an automatic identification method and system for suspected familial defects of power transmission and transformation equipment, including: collecting data of power transmission and transformation equipment, performing text analysis on defect information of power transmission and transformation equipment, and obtaining a characteristic word frequency matrix of equipment defect information; Defect information characteristic word frequency matrix, calculate the correlation between word frequency vector matrices and the similarity between different power transmission and transformation equipment defect information; based on the similarity between different power transmission and transformation equipment defect information, the power transmission and transformation equipment defect information Clustering is performed to identify suspected familial defective devices. The invention clusters the defect information of power transmission and transformation equipment, and automatically identifies suspected familial defect equipment according to the grouping statistical results, greatly reducing costs such as manpower and time.

Description

technical field [0001] The invention relates to the technical field of text mining, in particular to an automatic identification method and system for suspected familial defects of power transmission and transformation equipment. Background technique [0002] The safe and reliable operation of power transmission and transformation equipment is the basis for the safe operation of the power grid. Therefore, if there are defects in power transmission and transformation equipment, there will be potential safety hazards in the operation of the power grid, especially if the same manufacturer has the same technology, the same material, and the same design concept. The equipment defect caused by the system and ideas will cause a greater hidden danger to the safe and stable operation of the power grid. [0003] At present, the sources of familial defects of power transmission and transformation equipment mainly include: family accident notification of related equipment, equipment cou...
