Abstract

The high-frequency power transformer modeling is of significant importance for most power systems applications. This paper presents a simple black-box modeling methodology for power transformers using transfer functions, defined by the recorded voltage ratios at the transformer open-circuited terminals. The model parameters are estimated using an optimization method, minimizing the error between the measured and the calculated data. The proposed model is implemented in the ATP/EMTP software, using the ATP/MODELS language in order to simulate the transmission of power-line communication signals through the transformer.
