弧长约束下基于分布式倾角信息的输电线舞动曲线重建
Transmission Line Galloping Curve Reconstruction Based on Distributed Inclination Information and Arc-length Constraint
摘要
Abstract
Due to the effects of ice and wind, overhead transmission lines can dance. Therefore, for realizing the real-time monitoring of galloping of overhead transmission line, we propose a method based on distributed angle information and arc-length constraint of the galloping curve reconstruction. Through the arrangement of a series of angle sensor along the transmission line, we can get information on different arc length along the dip. According to the constraint relation between angle and arc length, we set up a function relation between the angle and the arc length, which can reconstruct the original wave curve. The simulation results prove the theory's correctness, which is based on the angle information and arc-length, and achieve that the error rate of the arc reconstruction is less than 0.3%. The experimental results show that this method is easier to measure and more precise to convert relative information to the absolute position information of the curve along the line. Meanwhile, this method, which verifies the low-error 1.357% reconstruction and realizes the real-time monitoring the galloping with practical engineering, makes the whole route condition to be intuitive.关键词
