Method and device for condition evaluation of transmission equipment based on multi-source heterogeneous data

Abstract

The invention provides a method and device for condition evaluation of transmission equipment based on multi-source heterogeneous data, and relates to the technical field of power system, wherein, themethod comprises the following steps: according to a preset state evaluation guideline, extracting key data matching with the parameter set in the state evaluation guideline from the obtained multi-source heterogeneous data of transmission equipment, wherein the multi-source heterogeneous data comprises a parameter and a parameter value corresponding to the parameter; Inputting the key data to the pre-trained model of transmission equipment defect classification, and getting the result of transmission equipment defect classification; inputting The classification results of transmission equipment defects to the pre-trained evaluation model of transmission equipment defects; According to the output results of the evaluation model of transmission equipment defects, judging the operation status of the current transmission equipment. The embodiment of the invention adopts defect classification and defect evaluation for multi-source heterogeneous data, and utilizes the mode of multi-algorithm cooperation to improve the intelligent analysis level of the evaluation of transmission equipment, thereby improving the accuracy of the evaluation of the transmission equipment.

Description

technical field [0001] The present invention relates to the technical field of power systems, in particular to a method and device for evaluating the status of power transmission equipment. Background technique [0002] The safety of power transmission equipment is the basis for safe, reliable and stable operation of the power grid. Effective and accurate assessment, diagnosis and prediction of equipment status will not only directly affect subsequent risk assessment and maintenance decisions, but also improve power supply reliability and power grid An important way to run the level of intelligence. [0003] In order to ensure the stable operation of the power system to a greater extent and grasp the operating status of the power system in real time, my country has proposed the construction of a smart grid, which requires the use of new technical methods to realize online monitoring of the operating status of transmission lines and equipment. , On the transmission line, the ...

Problems solved by technology

[0004] In order to better evaluate the status of power transmission equipment, relevant data processing methods based on big data have gradually matured and have begun to be applied to power systems, such as neural networks, support vector machines, Bayesian networks, rough set theory, correlation analysis, Gray theory and other related algorithms have been applied to a certain extent in the engineering practice of power system data analysis, and have achieved corresponding results, but a single algorithm will expose the shortcomings of the algorithm itself when dealing with certain problems, and the application process will In the state evaluation of power transmission equipment, the information system is isolated, the judgment is highly subjective, and the intelligent analysis is insufficient.
