Abstract: The paper studies the induced voltage on the DC transmission lines induced by the AC in different power transmission modes, when they are erected parallel in the same corridor or on one tower, and analyze the effect of electromagnetic shielding methods. In the paper an EMI model to calculate the induced voltage, is constituted by the distributed capacitances based on the theory of conduction coupling. Results indicate that the induced voltages of different power transmission modes distinctly different. In the same corridor, the induced voltage of the large cross-section conductor is rough similarity with the normal conductor under otherwise equal conditions, but power transmission capability of these AC transmission lines is far. And the results indicate that the more additional ground wire and the bigger difference height, the smaller the induced voltage. On one tower, the induced voltage of the single-circuit compact arrangement (ob-triangular) is the smallest i!
n the same vertical distance, and the single-circuit compact arrangement (ob-triangular) in structure has the advantages. Adding ground wires and changing the vertical distance can restrain the induced voltage.
