摘要

根据直流输电系统的运行特点，结合PSCAD/EMTDC仿真结果和天广直流输电系统运行中的实际案例，分析了空载投入换流变压器时产生的励磁涌流、和应涌流对直流输电系统的正常运行可能造成的各种不良影响，简介了天广和贵广直流输电系统对此所采取的针对性措施，对未来直流输电工程的实施及安全稳定运行有一定的参考价值。

Abstract

Based on the characteristic of high voltage direct current（HVDC） transmission system and combined the simulation results of PSCAD/EMTDC and the actual cases in Tian-Guang HVDC transmission practical project， this paper analyzes the negative impacts on HVDC transmission system caused by the inrush current and the sympathetic inrush when converter transformers of other pole are energized. The correlative techniques to avoid this problem used in Tian-Guang and Gui-Guang HVDC transmission project is introduced at the end of this paper. Research carried out in this paper is valuable for development of HVDC transmission projects in the future.
