摘　　要：针对远距离大容量输电的需要和输电线路走廊占地及电磁环境的压力,提出了将紧凑型架空输电线路技术和柔性交流输电技术有机结合的柔性紧凑型输电系统。在介绍3种输电模式技术并初步仿真计算和比较其输送能力后,分析了实现这种输电模式将面对的综合性问题。研究结果表明,这种输电模式将有较强的远距离输送能力,同时具有紧凑型输电线路节约土地资源和改善电磁环境的特点,在我国"西电东送"的发展背景下,值得在超高压和特高压的输电等级上进一步研究实施。The stress from the right-of-way of lines and electromagnetic environment, the long-distance, large-capacity, saving-corridor and well-electromagnetic-environment power transmission mode is actually required in China. This paper proposes the concept of flexible compact transmission system, which would combine technical advantages of compact transmission line and flexible AC transmission system. It is promising to solve these problems synthetically with flexible compact transmission system mode. Its technical contents are introduced, and preliminary simulations and calculations in transmission capacity of flexible compact transmission system are performed, and the complex problems are discussed. The preliminary research shows that flexible compact transmission system will have large transmission capacity for long-distance power transmission, and obvious efficiency of saving corridor and meliorating electromagnetic environment because of characteristics of compact transmission lines. On the background of electric power system development strategy ＂transmission of electric power from the western to the eastern region＂ in China, the flexible compact power transmission systems are worthy of being researched and performed in EHV AC and UHV AC power transmission system.
