Transformer partial discharge map generation method based on generated adversarial network

Abstract

The invention discloses a transformer partial discharge map generation method based on a generated adversarial network. The method comprises the following steps of S1, taking a collected transformer partial discharge map with a label as an input sample set; S2, carrying out grayscale processing on the transformer partial discharge map with the label; S3, setting a random noise, and taking a Gaussian noise as the random noise which is about to be input; setting a loss function of a generator, getting the generator, taking the partial discharge map after grayscale processing and the random noiseas input of the generator, and passing the generator and generating a pseudo sample; S4, setting the loss function of a discriminator, generating the discriminator, taking the pseudo sample generatedin the S3 and an original partial discharge map as the input of the discriminator and determining, and carrying out parameter determination; and S5, after the parameter is determined, outputting theacquired transformer partial discharge map of the generated adversarial network if a device outputs 1, and abandoning if the device outputs 0. By using the method, the partial discharge map required by a researcher can be accurately generated.

Description

technical field [0001] The invention belongs to the technical field of online monitoring methods for transformers, and in particular relates to a method for generating partial discharge graphs of transformers based on generative confrontation networks. Background technique [0002] Transformer is one of the important equipments in the substation link of power system, if it breaks down, it will cause huge economic loss. Therefore, it is very necessary to carry out online monitoring and fault diagnosis of transformers. The common faults of transformers can be roughly divided into two categories: discharge faults and overheating faults. Discharge faults include: partial discharge, high-energy discharge and low-energy discharge. Among them, partial discharge is a kind of discharge in which only a part of the insulation system discharges without forming a penetrating discharge channel under the action of an electric field. The detection and evaluation of partial discharge is an ...
