摘要：

Digital twin is the key technology to realize the digital transformation of power equipment industry and promote the construction of new power system. As important power transmission and transformation equipment, how to build a transformer digital twin and promote the digital and intelligent development of transformers has become a key issue. This paper firstly summarizes the connotation of digital twin and its current research progress in power system, and then it proposes the framework of transformer digital twin system based on the demand of transformer operation and maintenance service as well as gives the realization conception of digital twin for transformer intelligent operation and maintenance by combining the maturity evolution process of digital twin, including five stages which are virtual body characterization, perception interaction, model-driven multi-field calculation, data-driven state analysis and intelligent sharing. For each stage the key technologies and methods of its implementation are analyzed. Finally, the practical application of digital twin of transformer intelligent operation and maintenance is prospected, and the challenges faced in its implementation are summarized. ©2023 Chin.Soc.for Elec.Eng.
