摘要
A calculation method for the electric field over the ground surface under double-circuit HVDC transmission lines is proposed to satisfy the engineering design requirement. A comparison of the calculation results with the experimental measurement results finds that the maximal values and lateral distributions of the electric field over the ground surface under this type of line are obviously affected by different pole arrangement schemes and unequal corona onset electric fields of the positive and negative poles, and the maximal values and lateral distributions of the electric field over the ground surface under this type of line with diversified pole arrangement schemes can be predicted by using this method.
