Summary: | The embodiment of the invention discloses a signal noise reduction method and device, equipment and a storage medium. The method comprises the following steps: acquiring an original partial discharge ultrahigh frequency signal; performing iterative decomposition on the original partial discharge ultrahigh frequency signal based on a set fitness function to obtain a plurality of first target intrinsic mode function (IMF) components; dividing the plurality of first target IMF components into a plurality of second target IMF components and a plurality of third target IMF components based on the kurtosis values of the first target IMF components; de-noising the plurality of second target IMF components based on a target wavelet coefficient and a target wavelet threshold to obtain a plurality of de-noised second target IMF components; and determining a target partial discharge ultrahigh frequency signal based on the plurality of denoised second target IMF components and the plurality of third target IMF components |
