我国紧凑型与同塔双回输电现状与展望

Current Situation and Prospect of Compact Line and Double Circuit on Same Tower in China

分析了紧凑型线路的原理、带电作业、对系统的影响和同塔双回线路的塔型、电磁干扰、耐雷性能、带电作业方式,结果表明,两种输电技术均有良好的经济技术效益,能较大幅度提高单位走廊输送容量。

Power transmission is very important to utilize energy sources in reason and to promote progress of the society. One direction of the electric power development is increasing transmission capacity in a corridor. In this paper, compact line and double circuit on same tower is introduced, both of them can increase transmission capacity in a corridor greatly. For compact line, the authors analyzes the principle, live working, effect on the system and problems needed to be further researched; and for double circuit on same tower, the tower style, electromagnetic disturbance, lightning protection performance and live working style are researched. The results indicate that the two power transmission methods are feasible in technology and have superiority in economy and technology.
