Title:
TRANSFORMER HEALTH INDEX EVALUATION METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/082298
Kind Code:
A1
Abstract:
The present application relates to a transformer health index evaluation method and apparatus, a computer device, a storage medium and a computer program product. The method comprises: constructing a transformer two-level evaluation and determination system, the transformer two-level evaluation and determination system comprising a target layer, an object layer and a feature layer; constructing a transformer health index evaluation model on the basis of the transformer two-level evaluation and determination system and an object element extension principle, and obtaining the degree of correlation of an object element to be evaluated regarding each index evaluation level; obtaining an initial transformer health index and a transformer health correction factor on the basis of the degree of correlation of the object element regarding each index evaluation level; and correcting the initial transformer health index according to the transformer health correction factor to obtain a corrected health index of a transformer. Using the present method, the accuracy of transformer health condition evaluation may be improved.
