Research on Key Technology of Digital Twin of Transformer Equipment for Technology Compliance Assessment

With the rapid development of China's national economy and the sharp increase in power demand, the rapid growth of the number of transformers makes the requirements for equipment quality control and equipment evaluation methods urgently need to be further improved. This paper carries out research on transformer technical conformity assessment, which can realize data storage, data mining and correlation analysis. The digital twin constructed can convert data into assets, and then establish a complete set of digital management service system of transformer equipment, which is conducive to improving the intelligent level of technical conformity assessment of main equipment. The technical conformity evaluation database was established and the data differentiation analysis was completed. An early warning mechanism for key data of transformer technical conformity assessment is proposed, a digital platform for data management and analysis of conformity assessment is established to further improve the efficiency of technical conformity assessment, fully mine and analyze technical conformity assessment data, and improve equipment quality.
