Method for analyzing icing prominent influence factors of power transmission line

The invention discloses a method for analyzing icing prominent influence factors of a power transmission line, and the method comprises the following steps: firstly, obtaining the environment temperature, the environment humidity, the environment wind speed, the wire temperature and the wire tension through the online monitoring of the power transmission line and converting the wire tension into an actual icing thickness value through a theoretical computation model; and analyzing the relation between the actual wire icing thickness and the predicted icing thickness value, and the environmenttemperature, the environment humidity, the environment wind speed and the wire temperature and determining the prominent influence factors which influence the wire icing. The analysis method disclosed by the invention can be used for solving the problems of insufficient icing scene data source and insufficient result accuracy of the existing analysis method, defining an icing influence depth coefficient formula and obtain
