摘要

冻雨作为一种常见的灾害性天气，常导致高压输电线路积冰，当积冰达到一定的厚度后，覆冰的脱落会引发导地线间的闪络，进而导致城市电力供应大面积中断.在冻雨频发区域，故障线路相较于正常线路而言，呈现出导线位移和张力变化较大的显著特征.这些新的特征对现有监测方案提出了更高的要求，为此，本文提出一种基于无线位姿传感器的冻雨区输电线路监测方法.首先分析了无线位姿传感器的优势，开发对应的上位机，设计了一种将传感器安装在直线塔悬垂绝缘子串上，利用测量的倾角结合串长计算实时档距的方案；其次，算法解决实时线长难以测量的问题，并结合实时档距和实时线长得到导线动态张力提出一种基于导线弹性变形的输电线路监测算法，依据相似准则搭建四塔三线输电线路缩比实验平台，验证模型的有效性.结果表明：该方法可以有效利用位姿传感器的实时数据实现对线路张力和位移进行实时精准监测，为电力系统的安全稳定运行提供了有力的技术支撑.

Abstract

Freezing rain is recognized as a common hazardous weather condition that often results in ice accumulation on high-voltage transmission lines. When the ice reaches a certain thickness

the shedding of ice cover can trigger flashover between grounded wires

leading to widespread interruptions in urban power supply. In regions prone to frequent freezing rain

power lines experiencing ice shedding oscillations exhibit significant characteristics of wire displacement and tension variation compared to normal lines. These new features impose higher demands on existing monitoring schemes. Therefore

this study proposed a method for monitoring ice shedding oscillations on transmission lines based on wireless attitude sensors. Firstly

the advantages of wireless pose sensors were analyzed

and a scheme was designed to install the sensor on the suspension insulator string of a straight tower

using the measured inclination angle combined with the string length to calculate the real-time span. Secondly

an algorithm was designed to solve the problem of difficult measurement of wire stiffness and real-time wire length

and combined with real-time span and real-time wire length to obtain the dynamic tension of the wire. Then

a transmission line monitoring algorithm based on the wire elastic deformation model is proposed

and a four towers three lines transmission line scaling experimental platform is built based on similarity criteria to verify the effectiveness of the model. The results show that this method effectively utilizes real-time data from attitude sensors to achieve precise real-time monitoring of tension and displacement on ice-shedding transmission lines

providing robust technical support for the safe and stable operation of power systems.
