中文摘要	In China there are still not experiences in the design and operation of double-circuit HVDC transmission lines. For this reason, the authors calculate the total electric field and ionic current density caused by corona effect of double-circuit HVDC transmission lines, and analyze the impacts of different conductor configurations and structural parameters such as conductor inter-spacing, line height to ground, number of sub-conductors and conductor radius, on ground ionic current density and field strength. Calculation results show that the ground total electric field strength and the ionic current density is smaller while the two transmission lines are configured vertically; under the same conductor dimension and line height, the ground field strength of rationally configured double-circuit transmission lines is far less than that of single-circuit transmission line; the smaller is the double-circuit lines' vertical inter-spacing, the less are the ground field strength and ionic current; in addition, the electromagnetic environment of double-circuit HVDC transmission lines is superior to that of single-circuit transmission line.
