特高压交流输电线路采用同塔双回路技术研讨

随着电力需求的增加,规划中的许多特高压交流输电线路工程处于华东经济发达地区,针对日益紧张的路径状况,为缓解华东土地资源稀缺矛盾,提高线路走廊利用效率,提高华东电网输送能力,合理利用土地资源,特高压交流输电线路工程采用同杆架设将极大缓解经济发达地区没有路径走廊的矛盾.通过对国内外500 kV及1 000 kV同塔双回输电现状、特高压交流采用同塔双回路的优势、技术上的可行性、线路设备的国产化能力以及检修和维护等方面进行分析论述,论证了特高压交流采用同塔双回架设技术上是完全可行、合理的.

Discussion to Double Circuit Same Tower Technique On U.H.V.A.C.Transmission Line

Locating in the developed regions of East China,many planned Ultra High Voltage Alternative Current Transmission Lines now face conflicts between increment of power requirements and lack of land resources.Adopting Double Circuit Same Tower Technique On U.H.V.A.C.can ease up those conflicts,raise efficiency of channel using and extend transmission capacity of East China Power Grid.This paper describes status quo of Double Circuit Same Tower Technique on 500 kV and 1 000 kV lines,the advantages and feasibilit...
