摘　　要：高压直流输电线路故障后的快速清除和恢复对整个系统的稳定、可靠运行至关重要。文中分析总结了现有基于电网换相换流器的高压直流(LCC-HVDC)系统和基于电压源型换流器的高压直流(VSC-HVDC)系统中直流线路故障清除及恢复策略。指出现有策略中存在盲目恢复的不足,会对整个系统造成更大的冲击或者不必要的停运。提出了一种可能的解决方案:在不同直流输电系统中展开直流输电线路故障自适应恢复研究,实现直流输电系统的安全、快速恢复,完善直流线路故障综合处理方案。The fast fault clearing and recovery of high voltage direct current ( HVDC) transmission line are very important for the stable and reliable operation of the entire power system.This paper analyzes and summarizes the existing clearing and recovery strategies of DC line faults in both line commutated converter based HVDC (LCC-HVDC) system and voltage sourced converter based HVDC (VSC-HVDC) system.It is pointed out that the blind recovery in existing strategies will make greater impact on the entire system or unnecessary outage.A possible solution is proposed that the adaptive recovery of DC line faults in different HVDC transmission systems should be studied to achieve the safe and rapid recovery of HVDC transmission system and improve the comprehensive processing method of DC line faults.
