Dynamic Response Simulation Research on Ice and Snow Removal of Overhead Transmission Lines with UVA Line Collision
摘要
Abstract
Increased longitudinal bouncing and dynamic tension in conductors during the growth and shedding of ice and snow on transmission lines poses a great threat to the stable and safe operation of the power system.This paper focuses on a UAV-mounted payload collision de-icing strategy for snow-covered transmission lines,and establishes a finite element model based on acceleration criteria for snow and ice detachment to numerically simulate the snow and ice removal process and dynamic ice-shedding responses,analyzes the complex effects of multiple factors-including impact location,span length,impact load parameters(magnitude and angle),and ice/snow thickness on snow and ice removal rate,tension increase,and ice-shedding jump height.The results demonstrate that when applying identical impact loads,the 1/4 span position achieves optimal de-icing efficiency with minimized operational risks.Although increasing impact loads progressively enhances de-icing rates while simultaneously elevating jump heights and tension surge risks.Thicker ice/snow layers require higher energy consumption for de-icing,therefore it is recommended to use a graded loading impact method for snow and ice removal in practical engineering.关键词
