Abstract

The invention discloses a fault diagnosis and early warning method based on multi-source data fusion and a convolutional twin neural network, and the method comprises the steps: constructing a data dictionary for various types of data in the collected vibration information of a power transformer, the concentration information of gas dissolved in oil, the infrared information of the power transformer, the voltage information and the current information; standardized integration is carried out on the collected data, data information is extracted through double-space features, fault identification and classification of the power transformer are realized by using the convolutional twin neural network, and the fault diagnosis efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of power transformer fault diagnosis, in particular to a fault diagnosis and early warning method based on multi-source data fusion and convolution twin neural network. Background technique [0002] For a long time, my country's maintenance strategy for transformers has mainly adopted time-based regular maintenance, which has the defects of "over-maintenance" and "insufficient maintenance", which is blind and mandatory, resulting in a lot of waste of manpower and material resources. And it increases the probability of new hidden dangers. Considering the big data characteristics of transformer operation information and the diversity and complexity of fault types, the new round of technological revolution and industrial transformation requires power equipment to transform to intelligent and high-end. The artificial intelligence algorithm can establish a simulated nervous system for information processi...
