Abstract

This paper presents a digital-twin-based approach to developing a new protective relay for power transformers. The proposed approach receives the real-time electrical measurements from each side of a transformer and calculates the other side parameters through an accurate transformer model. It then compares the measured and calculated ones and finds out whether the differences are caused by noises and inaccuracies or internal faults.The performance of the proposed method was evaluated through time-domain modeling of non-linear power transformers with hysteresis using Matlab/Simulink/Simscape. The results demonstrate that the proposed method is able to detect internal faults sensitively and selectively. However, the effects of different derating parameters will be added to the model for the betterment of its performance.
