Embodiment Construction
[0020] A transformer winding fault intelligent identification method, the invention is characterized in that:
[0021] 1) Actively inject pulse signals into transformer equipment to obtain transformer winding network curves;
[0022] 2) Obtain the transformer vibration frequency response curve based on the vibration frequency response method;
[0023] 3) performing feature extraction on the obtained winding network curve;
[0024] 4) performing feature extraction on the obtained vibration frequency response curve;
[0025] 5) Extract the winding network curve characteristics and vibration frequency response curve characteristics of the transformer winding fault library to train the support vector machine SVM;
[0026] 6) Input the newly detected winding network curve characteristics and vibration frequency response curve characteristics into the support vector machine SVM for winding fault identification, and determine whether there is a winding fault inside the transformer ...
