Research on Digital Twin Model and Visualization of Power Transformer

With the introduction of national-level strategic concepts such as intelligent manufacturing and Industry 4.0, more and more people are beginning to pay attention to information, sensing, artificial intelligence and other technologies. Digital twins are the key to achieving digitalization in various fields. Compared with On-line monitoring or fault diagnosis technology, the obvious advantages of digital twins are timeliness, two-way prediction, and high visibility. The model is also the key to the application of digital twins. The creation of models is related to the accuracy and visualization of digital twins. This article summarizes the development of digital twins and establishes the physical model of the transformer. Three-dimensional model of crystal alloy transformer, no-load test and short-circuit test are performed on the model, and the real-time change graph of the magnetic flux density in the iron core during no-load simulation operation is given. Finally, the development of digital twins in the field of power systems is prospected.
