In order to improve the reliability of power supply, it is necessary to study the intelligent transformer of the key equipment in the smart substation. Firstly, the transformer model based on the magnetic coupling mechanism is given according to the magnetic coupling characteristics of the transformer. Then, considering the static coupling characteristics of the transformer under high frequency conditions, an improved transformer model based on wide frequency mechanism is obtained. Finally, the effectiveness of the proposed model is verified by comparing the simulation data with the actual measured data for an actual object.
