Abstract :
The winding hot-spot temperature is an important parameter that determines the transformer overloading capability and the aging rate of the oil paper insulation. In this paper, three simulation models based on modified IEEE model, Swift model, and Susa model are established in Matlab/Simulink. The top-oil temperature and hot-spot temperature in the models are calculated using Runge-Kutta method. Simulation results showed that Susa model and modified IEEE model are in good consistency while there is quite a difference between Swift model and modified IEEE model.
