Analysis and Evaluation of the DC Magnetic Bias for 1000kV Ultra-High Voltage Transformer Caused by Changsha Rail Transit

In this paper, the stray current distribution network model of Changsha rail transit system is constructed from the perspective of the stray current induced by rail transit in the adjacent substation. We evaluated the degree of influence of the stray current of urban rail transit lines after the com...

Summary:In this paper, the stray current distribution network model of Changsha rail transit system is constructed from the perspective of the stray current induced by rail transit in the adjacent substation. We evaluated the degree of influence of the stray current of urban rail transit lines after the completion of the Changsha 1000 kV UHV substation, which provided a reference for the UHV transformer DC bias prevention experience.
