特高压直流培训基地±500 kV双回路塔导线布置方案探讨

Discussion on Conductor Arrangement Scheme of ±500 kV Double Circuits Tower in Ultra HVDC Training Base

随着南方电网特高压直流线路建设的发展,特高压直流培训基地的建设和学员技能培训意义重大。根据一拟建特高压直流培训基地的场地特点,结合已建线路的相关参数,对4种±500 kV双回直流铁塔的导线极性布置方案进行计算、分析和对比。最后综合考虑工程实际、各项培训需要及投资成本等因素,确定了优化设计方案。

With the development of uhra HVDC line in the southern power grid, it is of great significance for the construction of ultra HVDC training base and the skill training of students. According to the site characteristics of an ultra HVDC training base to be built and the technical parameters of transmission line built, four kinds of conductor polarity layout schemes of ±500 kV double circuit tower are calculated, analyzed and compared. Finally, the optimal design scheme is determined by comprehensively considering factors including the actual situation of the project, every training needs and investment cost and so on.
