高压直流输电的前沿技术

HVDC transmission technologies at the frontier

大容量、远距离输电已经成为我国电网发展的趋势,而直流输电技术在大容量、远距离输电中占有极其重要的地位。开展高压直流输电的前沿技术研究,对我国电网的建设和安全稳定运行均具有重要的意义。结合高压直流输电技术在南方电网中的应用,重点介绍中国南方电网公司在直流输电和交直流混合电网运行技术、直流输电工程技术自主化及特高压直流输电技术方面研究的最新进展,包括在高压直流输电前沿技术方面的研究成果及其在南方电网中的应用。

Long distance, bulk power transmissions are the developing trend for power grids in China. HVDC transmission technology will take the key role in long distance, bulk power transmissions. The studies on the top end technologies of HVDC transmission are very impor- tant for construction of key transmission projects as well as stable operation of power systems in China. Based on the applications and studies of HVDC transmission technologies in China Southern power system, the research work on HVDC transmission technology and operation technologies of hybrid AC/DC power systems, ongoing studies and corresponding results on key technologies of HVDC transmission project and UHVDC technologies were introduced. The applications of research results in China Southern power system are demonstrated.
