摘要: 把单目视觉分析方法应用于输电线路舞动测量中,通过在舞动试验机和小档距试验线路上的对比试验,表明该方法测量精度较高,频率测量误差优于1%,幅值优于3%,证明了单目视觉分析方法在输电线路舞动测量方面的适用性和有效性。同时,采用该方法对500 kV真型试验线路的2次舞动事件进行了分析,得出了500 kV真型试验线路2次舞动的舞动幅值、频率和阶次等主要特征参数及线路舞动动态轨迹、特征点二维断面图,可以为500 kV输电线路结构和防舞装置设计提供参考数据。所研究的方法和得出的结论为如何防治舞动提供了基础方法和数据支持。

Abstract: Monocular visual analysis method is applied in measuring parameters of transmission line galloping in this paper. The comparison experiments on gallop test machine and small test line demonstrate high measurement accuracy of proposed method. The mismatch of frequency and amplitude measurement is less than 1% and 3%, respectively. The experiment data shows applicability and effectiveness of proposed method. Detailed analysis of two 500 kV galloping events of real size test transmission line are performed. Some parameters are obtained including amplitude, frequency, order, dynamic trajectories and two-dimensional section of feature points. Those results provide reference for design of 500 kV transmission line structure and anti-galloping device. The method and conclusion in this paper provide basic method and data support for galloping prevention and galloping mechanism study.

Key words: galloping, monocular visual analysis, real overhead transmission line, characteristic parameters, measurement
