| 摘要: |
| 母线保护的隔离刀闸位置是影响保护动作行为的关键因素，微机母线保护能自适应隔离刀闸位置：但如何在隔离刀闸辅助接点出错的情况下保证母差保护的正确动作是微机母线保护的难题。提出一种基于第三差动的双母线运行方式的纠错方法，可以保证母线保护在隔离刀闸出错的情况下正确地切除故障母线。 |

| Abstract: |
| The state of isolator is the key factor infecting the behavior of busbar protection. Digital busbar protection adapts automatically the isolator conditions;however,it is still a difficult matter to ensure the proper function of busbar protection when the isolator auxiliary contact is wrong. Error rectification schemes based on third differential current for dual-busbar operation mode are proposed,which may ensure the proper functioning of busbar protection under such situation. |
