【 摘 要 】

Firstly, the limitations of the existing transformer harmonic models both at home and abroad are analyzed. Based on this, the influence of the skin effect and the proximity effect on the windings under harmonics conditions is considered. Based on the electromagnetic field principle, the paper analyses the distortion characteristics of winding resistance parameters, introduces the AC power group coefficient and establishes of winding harmonic loss model. Compared with the traditional engineering calculation method, we can see that the theoretical model proposed in this paper can improve the accuracy and make the transformer winding loss calculation more accurate, Therefore, the model has certain guiding value for engineering calculation.
