摘要: 目前国内±800 kV特高压直流输电线路采用的最大截面导线为6×900 mm2钢芯铝绞线。在分析6×JL/G2A-900/75、6×JL/G2A-1000/80、6×JL/G2A-1120/90导线方案工程初期投资、电能损耗的基础上,对3种导线方案进行全寿命周期内经济性比较,论证了年损耗小时数较高时,采用6×JL/G2A-1000/80、6×JL/G2A-1120/90导线方案在±800 kV特高压直流输电线路上的经济性更优越。

Abstract: At present, the largest conductor applied on ±800 kV UHVDC transmission line is 6×900 mm2 ACSR. Base on analysis of preliminary stage investment and power loss, a life cycle economic comparison on 6×JL/G2A-900/75, 6×JL/G2A-1000/80, 6×JL/G2A-1120/90 conductor types is performed. It is verified that application of 6×JL/G2A-1000/80 and 6×JL/G2A-1120/90 conductor types in 800 kV UHVDC transmission lines has economic advantages when the number of annual power loss hours is relatively high.

Key words: UHVDC, large cross-section conductor, economic comparison
