dc.description.abstract | Calculation of power system transients involving transformers require models that incorporate capacitive
behavior. The paper outlines how classical low-frequency transformer models can be extended with capacitances
and how to fit the parameters based on typical values, test report and frequency response measurements.
Justified tuning factors are proposed. The responses of the models are compared to measurements in frequency
domain, and with detailed black-box models in studies of transient recovery voltage and lightning. The models
show reasonable agreement including the first resonance point, but with too low damping without proper
adjustments. | en_US |
