Transformer Digital Twin Development Framework and Functionality Demonstration

Industries are embracing the implementation of digital twin to improve reliability and efficiency of their systems. Even though the concept of digital twin is simple, its implementation is challenging due to various issues including the detailed framework which can vary depending on the type of industry. Power transformers are one of the greatest engineering inventions in the $19^{\text {th }}$ century that helped achieve today’s highly efficient electricity transport process. They are indispensable for the reliable operation of the power network, and managing these assets to their optimal lifetime without unexpected in-service failures is vital. While various modelling approaches have been utilized in design, operation and condition monitoring of power transformers, it is expected that implementation of digital twin will incorporate various physics/ knowledge based, data driven models into a single platform where data are of high fidelity, live and interchanged among models and support the best utilization of transformers with high reliability. This paper provides a demonstration of implementing a digital twin platform for power transformers through MATLAB software.
