输电线路舞动现场监测技术研究

Study on the Scene Monitoring Technology of Transmission Line Galloping

输电线路舞动对电力系统产生严重的破坏作用。舞动监测对于舞动机理研究、防舞装置开发和防舞方案制定都具有重要的意义。本文介绍了目前常用的舞动监测技术和各自的优缺点,阐述了基于单目视觉分析舞动监测技术的系统构成和关键技术,提出了基于线路特征的单目视觉标定方法。通过在尖山真型输电线路试验基地的实际应用,验证了基于单目视觉分析的输电线路舞动监测技术的实用性。

The transmission line galloping causes serious damages on power system. The monitoring of galloping isvery significant on studying galloping mechanism, developing anti-galloping device, and making anti-galloping solu-tion. This paper introduces some galloping monitoring technologies which are commonly used now, analyzes their ad-vantages and disadvantages, expounds the system structure and key technology of galloping monitoring technologybased on monocular vision analysis, comes up with the monocular vision calibration method based on transmissionline features.Through the practical application in jianshan transmission line test base, the practicability of transmis-sion line galloping monitoring technology based on monocular vision has been verified.
