摘要：
Due to shortage of land resources in China, there may be two or more transmission lines in sections of a transmission channel of ±1100 kV UHV DC project. Operation experience shows that due to polarity effect, lightning shielding characteristics of DC transmission lines have certain regularity comparing with AC transmission line. In order to study influence of adjacent lines on lightning shielding characteristics of ±1100 kV DC lines, this paper explores influence of different arrangement of polarity, height of adjacent lines and separation distance, et al to achieve the most cost-effective lightning protection scheme. In this paper, based on electrical geometric model, a lightning shielding simulation model witha ±1100kV line and other lines in parallel was built to calculate conductor striking frequency. Lighting shielding factor was introduced to quantitatively analyze effect of adjacent lines on ±1100 kV line shielding. It was found that there existed remarkable influence of polarity, tower structure (single-or double-circuit transmission lines), tower height and separation distance on lightning shielding characteristics. In construction of ±1100kV DC project, it is recommended that the positive polarity conductor should be arranged near the adjacent line side, thus reducinglightning shielding failure rate of ± 1100kV line. When the distance to adjacent lines is close, thelightning shielding failure rate of ±1100kV line is greatly reduced, anditcan be considered to simplify measures against shielding failure to cut costs. © 2017, Power System Technology Press.
