摘要：

This paper presents a model of the power transformer for electromagnetic transient studies, which employs a wavelet filter bank. In this model both the primary and the secondary windings are represented by stages of a wavelet filter bank where the dimensions of such a filter bank depend on the number of turns of primary windings and secondary windings. The basic building block consists of stages of the wavelet filter bank. Transformer total response is composed of the sum of responses of all stages, which depends on the nature of the primary current. Using the wavelet filter model, the losses due to eddy currents, leakage flux, and inrush currents have been studied. The proposed wavelet filter model has been found to be suitable for power transformer inrush currents including high frequency transient effects.
