Method and apparatus for monitoring partial discharge based on digital twin, device and medium

Abstract

A method and apparatus for monitoring partial discharge based on Digital Twin, an electronic device and a storage medium are disclosed, which relate to the technical field of partial discharge monitoring. The method includes: establishing a three-dimensional display model of a transformer; performing spatial digitalization on the three-dimensional display model to form a three-dimensional digital model of the transformer; establishing a transformer Digital Twin model according to an arrival time difference fingerprint library and the three-dimensional digital model; when a high-frequency monitoring channel, an ultra-high-frequency monitoring channel and an ultrasonic monitoring channel detect presence of a partial discharge signal in a transformer, recognizing a partial discharge spectrum corresponding to the partial discharge signal; recognizing, by a multi-source fusion recognition model, a partial discharge type according to the partial discharge spectrum; and according to a time difference of arrival of the partial discharge signal at each sensor in a locating channel, locating a partial discharge position of the transformer through the arrival time difference fingerprint library. According to the method in the embodiment of the present disclosure, the partial discharge can be accurately recognized and accurately located.
