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 a method and a system for automatically identifying suspected familial defects of power transmission and transformation equipment. The method comprises the following steps of:collecting data of power transmission and transformation equipment, performing text analysis on defect information of the power transmission and transformation equipment to obtain a characteristic word frequency matrix of equipment defect information; based on the characteristic word frequency matrix of equipment defect information, calculating the correlation between word frequency vector matrices and the similarity between the defect information of different pieces of power transmission and transformation equipment; and based on the similarity of defect information of different pieces of power transmission and transformation equipment, clustering the defect information of the power transmission and transformation equipment to identify equipment with the suspected familial defects. The invention clusters the defect information of the power transmission and transformation equipment and automatically identifies the equipment with the suspected family defects according to a grouping statistical result, thereby greatly reducing the cost of manpower, time and the like.

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...
