| Abstract: | A new, more effective and exact three-phase core-type transformer model based on saturation nonlinearity of its cores and yokes is proposed in this paper. The parameters of which can easily be found from its open-circuit and short-circuit test data together with its positive-sequence and zero-sequence saturation curves. This model can be used extensively in studying the steady-state as well as the transient state of the transformer itself. The corresponding interface of the transformer with the network provides a measure for simulating complicated power system performances as well.The results obtained by computation tally fairly well with the data measured from experiments. Thus the validity of the proposed model is verified. |
