| 摘 要： | 列举了在非全相运行状态下线路保护设计和实现中应考虑的问题.使用零序、负序分量的继电保护方案应被闭锁或做一定改进.在非全相运行期间可能发生系统振荡,此时,距离元件和方向元件的特性会变坏.文中针对这种情况的一些具体实践措施进行了深入讨论. |
| 关 键 词： | 非全相 线路保护 振荡 |

| Abstract: | There are some problems in design and implementation of line protection schemes under open-pole operations listed in the paper. Schemes that employ zero or negative sequence relays should be blocked or modified. Power system swings can happen during the open-pole period. At this time,the operating characteristics of distance elements and directional elements may deteriorate. Some concrete measures used to solve the mal-operation are deeply discussed in this paper. |
| Keywords: | open-pole condition line protection power swing |
