| 摘 要： | 线路舞动是输电线路覆冰后常见的事故类型,对电力系统的安全稳定运行产生严重的影响;因此输电线路舞动的研究一直以来是研究的热点。舞动是覆冰导线在风激励下产生的一种自激振动,会引起输电线路跳闸,严重时引起断线、金具破坏甚至倒塔等严重设备故障,造成长时间停运。对输电线路舞动的影响因素、机理研究及防治方法等方面进行介绍和综述;并对现有研究进行总结,指出今后可能的研究方向。 |
| 关 键 词： | 输电线路 覆冰 舞动 防舞装置 舞动监测 |

| Abstract: | s: Galloping is a kind of common accidents after icing and affects the normal operation of power system, galloping of transmission lines is a research focus for long time. Galloping is a kind of self-excited vibration with the help of wind, and it can give rise to the trip of transmission lines, disconnection and damage of fittings or towers, which cause a-long-time outage. This paper will introduce and analyze the influence factors of galloping, mechanism and prevention measures; meanwhile, summarize the existed researches and put forward some possible research directions. |
| Keywords: | transmission lines icing galloping prevention equipment galloping monitoring |
