摘要: 同塔四回输电技术是电网建设中解决输电走廊紧张、提高输电容量、实现“资源节约型”电网的有效手段。依托特高压交流输电技术研究成果,通过理论分析和数值计算对1 000 kV与500 kV同塔四回交流输电线路杆塔型式进行研究。借鉴超高压输电线路同塔四回输电技术的经验,基于2种典型杆塔结构,从电磁环境、防雷性能、覆冰校验和经济性等方面进行了比较和分析,选择出合理的杆塔型式,并推荐了塔头布置方案,为1 000 kV与500 kV同塔四回输电线路塔型设计提供借鉴和参考。

Abstract: Application of the four-circuit on one tower transmission technology is an effective way to solve the corridor shortage problems for transmission lines, and to improve transmission capacity and build the resource-saving power grids. Based on UHVAC-dedicated technological research results, a study was made through theoretical analysis and numerical calculation on the tower types of 1 000 kV and 500 kV four-circuit AC transmission lines on the same tower. Based on the experiences of EHV four-circuit AC transmission technology, two typical tower structures were analyzed in terms of electromagnetic environment, lighting performance, icing verification and economy. A reasonable tower type was selected, and the tower head layout scheme was proposed, which can provide a reference for tower design of 1 000 kV and 500 kV four-circuit AC transmission lines.

Key words: four-circuit transmission lines on one tower, electromagnetic environment, lightning performance, icing verification, tower head layout
