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。
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.The influence factors of galloping,mechanism and prevention measures will be introduced and analyzed; meanwhile,summarize the existed researches and put foryard some possible research directions.
