Icing prediction and early-warning method and system of power transmission lines

Abstract

The invention discloses an icing prediction and early-warning method of power transmission lines. The method comprises that image information and meteorological parameter information, collected by an unmanned plane, of the power transmission lines are obtained; whether icing occurs in the power transmission lines is determined according to the image information collected by the unmanned plane of the power transmission lines and image information of normal power transmission lines; if icing occurs, the icing thickness is calculated and displayed; according to the image information and meteorological parameter information, collected by an unmanned plane, of the power transmission lines, future icing growth condition of the power transmission lines is predicted, so that ice melting is carried out according to the icing growth condition; whether the meteorological parameter information reaches an early-warning value is determined; and if the meteorological parameter information reaches the early-warning value, the meteorological parameter information is transmitted to an expert system, and the expert system improves the data collection frequency of the unmanned plane. Management staff can know practical onsite conditions of the lines timely through the method, ice melting measures are taken on the basis of foundations, and technical support is provided for decision making in icing disaster rescue.

Description

technical field [0001] The invention relates to the technical field of prediction and early warning, in particular to a method and system for prediction and early warning of icing on transmission lines. Background technique [0002] The geographical environment of my country's Southern Power Grid is harsh and the natural climate conditions are complex. In recent years, transmission lines within the jurisdiction have been frequently affected by various natural disasters, causing huge economic losses and social impacts. For example, there are more than 50,000 kilometers of 35kV and above transmission lines in Yunnan Province, and more than 40% of the transmission lines are directly affected by icing, fire, and geological disasters in different regions and seasons. These areas have the characteristics of variable climate, complex geological environment, high mountains and dense forests, thick fog and strong wind. When natural disasters occur, highway traffic is prone to be blo...
