Application Research of Pose Sensors in Monitoring De-Lcing Oscillation in Frozen Rain Areas
摘要
Abstract
Freezing rain is recognized as a common hazardous weather condition that often results in ice accumula-tion on high-voltage transmission lines.When the ice reaches a certain thickness,the shedding of ice cover can trigger flash-over between grounded wires,leading to widespread interruptions in urban power supply.In regions prone to frequent freez-ing rain,power lines experiencing ice shedding oscillations exhibit significant characteristics of wire displacement and ten-sion variation compared to normal lines.These new features impose higher demands on existing monitoring schemes.There-fore,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 ten-sion 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 tech-nical support for the safe and stable operation of power systems.关键词
