摘要
通过对直流输电系统换相失败产生的机理分析,介绍了各种影响因素及其灵敏度.影响多馈入直流输电系统换相失败的因素更为复杂,大量的仿真结果表明:提高其中非故障子系统的短路比可以用来改善系统的换相过程,并介绍了抑制换相失败发生的一些具体措施.
In this paper, the cause of HVDC commutation failure is analyzed, and the influence factors and sensitivity are introduced. For multi-infeed HVDC system, the reason of HVDC commutation failure is more complicated. With lots of simulation,the results show that increasing SCR of non-fault subsystem can improve HVDC commutation procedure, so some methods of decreasing commutation failure are presented.
