Application of Mechanical Calculation Model for Overhead Transmission Line on Suspension Tower

摘要

The on-line monitoring system for overhead transmission lines requires accurate monitoring of the icing status of transmission lines.Based on the ice model of the suspension tower overhead line of South China University of Technology,this paper puts forward the calculation method of on-line monitoring of the ice content range based on the historical monitoring data,and analyzes the parameters of obliquities and the equivalent wire length And other factors on the calculation model of icing,the use of the Southern Power Grid disaster(icing)monitoring and pre-warning system monitoring data and on-site acquisition of artificial ice data to verify the effectiveness and accuracy of the above method.
