A generalized model research for transfomer based on magnatic circuit

In this paper a new generalized transformer model is developed., based on the magnetic circuit. The model can be used in the general and special transformer´s simulation. The model is relative to the transformer structure and parameters of model can be gotten from the structure characteristic of transformer. The established process of the transformer model is given particularly. The simulating calculation of three-phase and three-leg transformer is made and the result is satisfaction. Thereby the application of the proposed model to a test system shows its correctness and validity.
