摘要
全面介绍高压直流输电技术在世界范围内的应用情况,并简述光直接触发晶闸管阀、绝缘门极双极晶体管电压源换流器、接地极引线故障测量装置等新技术在直流输电工程中的应用。对我国直流输电系统的发展重点工程及其采用的主要新技术也分别做了介绍。
This paper summarizes HVDC transmission systems which are operating or underbuilding all over the world and gives a brief description of newest modern techniques applied in HVDC systems, such as direct light-triggered thyristors, insulated gate bipolar transistors and earthing pole failure detectors etc.HVDC systems in China are introduced in this paper.
