| 摘 要： | 天广、兴安直流在运行中已多次出现接地极线路电流不平衡保护动作，而且接地极线路故障监视装置没有启动。从接地极线路不平衡保护的原理以及整定原则角度分析了保护的动作情况，及接地极线路故障监视装置在运行中存在的不足之处，提出了改进接地极线路不平衡保护的原理、加强接地极线路保护与接地极线路故障监视装置之间的参数配合等方案以改善目前的运行状况。

| Abstract: | Electrodes Line Unbalance Protection (60EL) has releases several times in TSQ and GG2 HVDC projects, and electrode line monitoring system (PEMO2000) did not work. The operation of 60EL in those cases is analyzed. Shortcoming exists in co-ordination between 60EL and PEMO 2000. And suggestion on improving 60EL and co-ordination between 60EL and PEMO 2000 are also submitted. |
