摘要
目前中国正在为各大水电站规划输电距离达2000km的大容量高压直流输电方案,800kV特高压直流是当前首选的方案。全球现有的高压直流输电系统的最高电压水平限制在500￣600 kV。因此,必须深入研究提高的稳态和暂态电压应力对特高压直流换流站主设备设计产生的影响。必须对现有技术水平和制造能力进行评估。将集中讨论特高压直流输电关键设备的特殊设计要求。
Bulk power HVDC transmission schemes over distances of up to 2 000 km are currently under planning for various large hydropower stations in China. Ultra high DC voltage （UHVDC） in the range of up to 800 kV is the preferred DC voltage level for these applications. Currently world-wide existing HVDC schemes are limited to maximum voltage levels of 500 kV to 600 kV. Therefore the impact of increased steady state and transient voltage stresses on the design of the main equipment for UHVDC stations has to be carefully investigated. Adequacy of existing technologies has to be evaluated taking manufacturing capabilities into account. Focuses on specific design aspects for key UHVDC equipment to be taken into consideration.
