AI Technical Summary

Technical Problem

Existing substation diagnostic methods are unable to provide a comprehensive and accurate diagnosis of the complete operating status of equipment in complex scenarios, especially due to insufficient analytical capabilities during transient operating conditions such as equipment start-up and shutdown, resulting in insufficient reliability and accuracy of diagnostic results.

Method used

By receiving high-frequency waveform data and remote signaling data from the substation auxiliary power system, a two-dimensional time-frequency spectrum is generated and compared with a preset template for structural similarity. Combined with the polarity information of the reflected waveform data, the degradation index and defect nature information of the load are determined, and finally the fault diagnosis information is displayed on the interactive interface.

Benefits of technology

It enables accurate tracing of the root cause of faults in complex scenarios, improves the reliability and precision of diagnostic conclusions, distinguishes the root causes of electrical and mechanical faults, and provides deeper diagnostic information.

Abstract

The application discloses a kind of intelligent interactive diagnosis methods based on transformer substation multidimensional information cloud computing power fusion, belong to fault diagnosis field.This application is applied to cloud computing power platform, first receive the high-frequency waveform data of transformer substation auxiliary power supply system and operating remote signaling data, according to load start-stop event mark positioning start-stop event window, and the waveform data in window is carried out multi-scale time-frequency decomposition to generate two-dimensional time-frequency spectrum;After that, the atlas is compared with the template by structure similarity, and the degradation index of each load is generated and displayed.Then receive the detection instruction of selected target load by user, trigger to the branch cable of this load and inject preset square wave pulse and collect reflected waveform data.Finally, the cloud computing power platform determines the polarity information of the reflected waveform data to obtain the defect property information, and according to the defect property information and the degradation index, the final fault diagnosis information is determined and displayed in the diagnosis rule knowledge base, which can improve the reliability and accuracy of diagnosis.
