Abstract: This paper designed a kind of export power transformer at the end of long transmission line. Analysis was made to the calculation method of transformer power supply voltage change caused by impedance voltage drop of superior bus and transmission lines, as well as the relationship of the voltage regulating mode, power supply fluctuation range and frequency at the primary side of transformers. It is pointed out that in the process of transformers design, the comprehensive analysis should be carried out for the concrete project, the reasonable selection should be made for transformer parameters and the transformer structure should be improved.
Key words: transformer; voltage regulation; structure design
