Problems solved by technology

The traditional secondary equipment defect data analysis method currently used is only simple comparison, statistics, abnormal identification, etc. for traditional secondary equipment. On the one hand, important characteristics such as coupling and correlation between data are ignored in simple analysis. On the other hand, the degree of automation and intelligence is not high, and the analysis technology and tools are lacking, which restricts the application effect

Abstract

The invention discloses an electric power secondary equipment defect data mining method and system in the technical field of electric power secondary equipment. The power secondary equipment defect data mining method comprises the following steps: acquiring operation data of power secondary equipment; performing fault information identification on the collected operation data of the electric power secondary equipment according to a preset rule to obtain a fault information identification result; and a fault information identification result is sent to an expert database for verification, and mining of defect data is completed. According to the method, the weak links of the secondary equipment are effectively analyzed, the reasons for inducing the weak links are found in a tracing manner, the coupling and incidence relation between data can be mined, and reliable reference basis is provided for operation, maintenance and management and control of the power secondary equipment.

Description

technical field [0001] The invention belongs to the technical field of electric power secondary equipment, and in particular relates to a method and system for mining defect data of electric power secondary equipment. Background technique [0002] The reliable operation of power secondary equipment is an important guarantee for the safety and stability of the power system. In recent years, with the rapid development of the economy, the scale of the power grid has continued to expand, and the number of secondary equipment in the power grid has also grown by leaps and bounds. The contradiction of "more equipment and fewer equipment" has brought considerable The large workload also brings risks to the operation of the power grid, and the level of operation, maintenance and control of secondary equipment needs to be improved urgently. The traditional secondary equipment defect data analysis method currently used is only simple comparison, statistics, abnormal identification, et...
