中文摘要: 结合远距离大容量输电方式的研究成果,采用最小年费用法对特高压交流输电、特高压直流±800 kV输电、特高压直流±1000 kV输电和半波长交流输电4种输电方式的经济性进行了定量计算,对比了不同输送距离下输电方式的经济性,认为在超远距离输电方式中,半波长交流输电具有明显的优势.
Abstract:Combined with the latest research finding in the long-distance transmission, using minimum annual cost method, the economy of four kinds of power transmission systems, i. e., UHV AC transmission system, ±800 kV DC transmission system, ±1 000 kV DC transmission system and Half-wavelength AC transmission system, are studied by quantitative calculation. The economy of different transport distances is compared, and a qualitative conclusion of economic ultra-long-distance transmission mode selection is drawn.
