同塔双回紧凑型特高压输电线路的研究现状与发展

Research Status and Development of Double Circuit Compact UHV Transmission Lines on the Same Tower

为了满足社会用电不断增长的需求,进一步降低电能输送成本,缓解线路走廊等土地资源日益紧张的局面,近些年来,人们对紧凑型特高压输电技术进行了大量的研究。相导线倒三角布置的同塔双回紧凑型输电线路作为一种新型输电技术,得到了越来越多的关注。本文介绍了该新型输电线路的概念、电磁特性、当前研究的热点问题,并对其应用前景作了简要展望。最后对我国当前特高压电网建设提出了采用同塔双回紧凑型输电线路的建议。

In order to meet the growing demand for social power consumption, further reduce the cost of power transmission, and alleviate the increasingly tense situation of land resources such as corridors and corridors, in recent years, people have done a lot of research on compact UHV transmission technology. As a new type of transmission technology, the same tower double-circuit compact transmission line with reversed-phase triangle arrangement has received more and more attention. This paper introduces the concept, electromagnetic characteristics and hot issues of the new transmission line, and gives a brief outlook on its application prospects. Finally, the proposal of using the same tower double-circuit compact transmission line is proposed for the construction of the UHV power grid in China.
