Research and application of transmission line environmental monitoring based on optical fiber sensing technology

Abstract

In this paper, the optical fiber sensing technology is taken as the research object. Firstly, according to the demand of the sensing layer of the power Internet of things, a transmission line environment online monitoring system is proposed based on the multi risk monitoring of external breakage, fire, icing, galloping and so on of the cable (overhead line), the composition and deployment of the monitoring system are introduced. Secondly, based on the research of temperature field and stress field distribution of optical fiber, combined with big data and artificial intelligence, the important environmental parameters of the line can be monitored. Finally, taking different monitoring scenarios as examples, this paper expounds the different monitoring functions of the environmental monitoring system of the Internet of things for transmission lines, which provides useful reference for environmental monitoring of transmission lines.
