Title:
SEPARATION AND IDENTIFICATION METHOD FOR MULTI-SOURCE HYBRID ULTRA-HIGH FREQUENCY PARTIAL DISCHARGE DIAGRAM
Document Type and Number:
WIPO Patent Application WO/2023/213332
Kind Code:
A1
Abstract:
The present invention discloses a separation and identification method for multi-source hybrid ultra-high frequency partial discharge diagram, which comprises: obtaining a PRPD diagram for ultra-high frequency partial discharge signals, carrying out standardization processing, and constructing and labeling a partial discharge sample database; constructing a PRPD diagram dataset of partial discharge signals and noise signals; determining a deep learning network to serve as a detection model, and inputting detection model parameters; dividing up the PRPD diagram dataset, and inputting same into deep learning network detection models for training; adjusting the detection models and training parameters; retaining and evaluating the trained models, and selecting the model with the optimal effect as a PRPD diagram detection model; and using the selected detection model on a diagram to undergo identification to analyze and confirm detection targets one-by-one, and retaining a final detection result and a multi-source separation result. The present invention solves the problem where when a plurality of partial discharge signals are actually present when using an image recognition algorithm to perform discharge type identification on a GIS ultra-high frequency PRPD diagram, there is no way to individually detect each signal.
