摘要
直流滤波器保护是决定特高压可靠运行的关键环节,但常出现误动的情况,其中C1不平衡保护误动比率大,且原因难以查找,因此通过对C1不平衡保护动作特性进行分析,进一步探讨C1不平衡保护参数配置的合理性,以确保保护正确、可靠动作。
DC filter protection is the key link affecting the reliable operation of UHV,but misoperation often occurs.Among them,C1 unbalanced protection has a high misoperation rate and the reason is difficult to find.By analyzing the operation characteristics of C1 unbalanced protection,the rationality of parameter configuration of C1 unbalanced protection was further discussed to ensure correct and reliable operation of protection.
