2011年7月26日江陵换流站极II直流线路遭遇正雷击,在直流系统再起动过程中站内功率反转保护突然动作闭锁直流极。本文通过现场录播图对直流系统遭遇雷击故障后的再起动过程进行了描述,在此基础上结合功率反转保护的动作逻辑对此次故障的整个过程进行了理论分析和仿真试验,最终提出了保护动作的合理原因。

The DC pole Ⅱ was blocked by the reverse power direction protection, when the DC transmission line of the pole Ⅱ was stuck by lighting on July 26, 2011. This paper introduces the restarting process after the lighting stoke fault by fault recorded data. On this condition, the paper analyses the whole process of the fault by combining the logic diagram of reverse power direction protection and it ~ives some reasonable cause~ at last
