摘要
Abstract
There is no experience in design and construction of±800 kV and±500 kV double-circuit DC transmission lines on the same tower, which improves utilization rate of the power transmission corridor effectively. For electromagnetic environmental problem, the total electric field, ion current density, radio interference and audible noise under different types of towers and conductor arrangements are calculated based on Deutsch assumption and empirical formulas. The results show that the required line-to-ground height is smaller while±500 kV line are arranged on the lower arm, the required width of corridor is narrower but the audible noise is higher when the same polarity are arranged on different side. The electromagnetic environment is also analyzed under different conductor types, conductor distances and height to ground, and the results provide reference for project design.关键词
