摘要
为降低直流特高压(UHV)输电线路的工程投资,结合±500 kV和国外已建UHV的经验,分析了现有杆塔荷载和经济档距。根据工程实际情况,计算了塔型方案中各塔的摇摆角系数、水平档距、垂直档距、摇摆角角度及塔头间隙等。计算确定,在理想平地情况下的经济塔高为51 m、经济档距为510 m。研究结果已被应用于云广±800kV线路。
In accordance with ± 500 kV DC overhead transmission line in China, and to research whether existing tower load plan is the same as UHV DC overhead transmission line, this paper discusses and researches tower load plan and economic span length of UHV DC overhead transmission line, On the basis of characteristics of project, the rational economy tower height and economy span length of UHV DC overhead transmission line are determined to reduce investment of project of UHV DC overhead transmission line.
