Transformation Ratio Impact-considered Transformer Power Loss Model
Most of the published works on transformer power loss did not consider the influence of transformation ratio.In view of this the present work made an attempt to preliminarily analyze the impact of transformation ratio to transformer loss parameters and to incorporate this impact in modeling.According to the transformer's electromagnetic characteristics,working principle,and loss characteristics,the relationship between main flux and transformer winding,and that between main flux and the given power supply voltage,as well as the connection between winding resistance and transformation ra-tio,were analyzed.Then the transformer power loss model was deduced by combining the aforementioned relationships and equipment technological parameters.The proposed model was indicated by case analysis to facilitate power loss reduc-tion and economic operation of transformers,compared with currently prevailing models,by reasonable allocation of transformer taps.
