输电线路导线舞动在线监测技术研究现状

Research Status of On-line Monitoring Technique of Conductor Galloping of Transmission Lines

介绍了输电线路舞动在线监测系统的结构和功能,综述了国内外舞动在线监测方法及其存在的问题。开发了基于惯性传感器的导线舞动监测系统,经现场运行,可提高现行导线舞动监测系统的位移精度。进一步的研究方向是优化各种监测技术,完善舞动机制、光纤传感网络和复用技术在输电线路在线监测的应用。

The structure and functions of an online monitoring system for transmission line galloping are presen- ted, and the methods to monitor galloping on transmission line home and abroad are summarized and defects in these methods are pointed out. The transmission line conductor galloping monitoring system based on inertial sensor is de- signed and the displacement error precision of the current galloping monitoring system is improved. It is pointed out that the further direction in the research of on-line monitoring of galloping is optimizing on-line monitoring methods, perfecting the principle of galloping and applying optical fiber sensing net and multiplexing technologies to transmis- sion lines.
