摘要:

导线选型在特高压直流输电工程中占有重要地位,导线选型既要满足输电线路的电气性能、机械性能的要求,又要具有一定的经济性。采用全寿命周期的经济性计算方法,对1 000 mm2和1 250 mm2不同截面及分裂数的导线在±800 kV和±1 100 kV直流输电线路中应用的技术经济性进行了比较和分析。分析结果表明,损耗小时数、上网电价对导线选型具有直接影响,导线选型应综合考虑各影响因素,确定合理的导线方案。

Abstract:

Conductor selection is critical in the design of UHVDC power transmission project, which should not only meet the requirements of electrical and mechanical performance of transmission lines, also should be economic. The technical economy of conductors with different cross-section (1 000 mm2 and 1 250 mm2) and multiple bundled in ±800 kV and ±1 100 kV DC transmission lines were compared and analyzed, based on the economic calculation method of total life cycle. The analysis results show that the conductor selection is strongly influenced by power loss hour and feed-in-tariff price, so the conductor selection should comprehensively consider all the factors to determine a reasonable conductor scheme.

Key words: ultra high voltage (UHV), DC power transmission lines, large cross-section conductor, total life cycle, economic analysis, conductor selection
