초록
Many unbalanced factors of underground transmission power cable, such as burying types and the length difference of the cable between each minor section, etc will cause the impedance unbalance and excessive circulating current between cables. So this paper presents the analysis of sheath circulating current in accordance with the distance between the center conductors and phase arrangement. ground resistance value changes on 154kV transmission system. Based on these simulation results, this paper will contribute to the reduction method of sheath circulation current.
