摘要

This paper starts from the regular phenomenon of transformer DC magnetic bias caused by ground - into stray DC. The distribution mechanism of stray current in the soil is analyzed and the multi-system coupling mathematical model for corrosion evaluation and seismic source prediction is constructed. Then, the data of power grid, oil pipeline and geomagnetic intensity in Hunan Province are input into the model for simulation. Effective prevention and prediction programs are obtained. Moreover, this paper provides reference for the application of the calculation and analysis of ground-into stray DC to other industries besides power system.
