摘要
Abstract
Transmission lines are erected on the field,affected by natural disasters in larger range and deeper degree,while the icing disasters caused econonic losses particularly severe.Based on the analysis of the existing icing monitoring device,we propose the method of transmission line icing wide-area monitoring based on OPGW.The method is based on the OPGW cable inner optical fiber as sensor and optical fiber Brillouin scattering technique,to analyze the relationship between the ice and the cable temperature variation which combines with the ice cover wide-area monitoring principle model.In this paper,the thermodynamic simulation of the cable temperature changes on the OPGW ice and no ice state is established by using the finite element analysis software.To verify the performance of this method,a field test is carried out on a transmission line tower of the icing experimental base.Results show that,transmission line icing monitoring based on OPGW can accurately locate and identify the ice coating section and not iced section,which can realize icing wide-area monitoring.关键词
