摘要

以兴安直流宝安换流站一起双极跳闸事故为例，介绍了兴安直流保护系统中直流过电压保护原理，以及接地极电流不平衡保护原理，重点分析了这次事故发生的原因，指出了兴安直流工程中直流保护系统存在的不足，并提出了相应的改进措施。

Abstract

Take a bipolar trip in Xing'an HVDC project at Baoan converter station as an example， the direct current（DC）overvoltage protection principle， and the electrode current unbalance protection principle in DC protection system are introduced， and the reason for this fault is analyzed. The problems existed in the DC protection system are pointed out， and some improved measures are brought forward.
