Abstract

The invention discloses a transformer substation equipment sound fault detection and positioning method based on deep learning, and the method comprises the steps: obtaining the sound data of transformer substation equipment, carrying out the data labeling of the sound data of the transformer substation equipment, and generating a sample data set; carrying out data enhancement on the sample data set by adopting an audio noise adding mode, and carrying out data preprocessing on substation equipment sound data in the enhanced sample data set to generate a multi-channel spectrogram sequence; forthe multi-channel spectrogram sequence, constructing a substation equipment sound fault detection model based on convolutional neural network coding and long-term and short-term memory network detection; and training the substation equipment sound fault detection model according to the sample data set to obtain a trained substation equipment sound fault detection model, and performing fault detection and positioning on the substation equipment sound. According to the technical scheme, the problems of low detection efficiency, poor algorithm robustness and the like in an existing substation equipment sound fault detection technology are solved.

Description

technical field [0001] The present application relates to the technical field of fault detection, in particular, to a method for detecting and locating sound faults of substation equipment based on deep learning. Background technique [0002] Substation is an important infrastructure of my country's power grid construction. There are many internal working equipment, and some power equipment will have breakdown and abnormal discharge. Abnormal sound is the most obvious sign of substation equipment failure, and the type and location of the fault can be quickly determined based on the sound. However, since each equipment in the substation has different sound pressure levels and frequency characteristics, the substation will form a reverberant sound field with multiple noise sources, which brings great difficulty to the fault detection and location of substation equipment based on sound. [0003] At present, the traditional sound fault detection methods of substation equipment ...
