Judgment method of icing early warning based on multi-source data fusion

Abstract

The invention discloses an icing early warning determination method based on multi-source data fusion. The invention relates to the technical field of icing early warning, and solves the problem that in the prior art, the possibility of icing in each area cannot be predicted and the accuracy of the early warning is reduced. Through The icing prediction unit analyzes the environmental information to predict whether each area is icing, divides the area where the circuit to be detected is located into several sub-areas, obtains the environmental information, and obtains the icing prediction coefficient of the sub-area through the formula Xi, if the icing prediction coefficient Xi of the sub-region ≥ the threshold value of the icing prediction coefficient of the sub-region, the corresponding sub-region is marked as an icing sub-region, and the wind direction of the cold air is obtained, and then according to the time sequence of the cold air arriving at the sub-region , to sort each ice-covered sub-area, to predict the ice-covered area in each area, and to judge the time sequence of the ice-covered areas, so as to improve the accuracy of early warning.

Description

technical field [0001] The invention relates to the technical field of icing early warning, in particular to an icing early warning determination method based on multi-source data fusion. Background technique [0002] Icing of transmission lines will not only affect the operation and maintenance work, but also lead to major accidents such as short-circuiting, flashover of insulators, and tower collapse of short-circuited lines in severe cases. Transmission line ice damage has the characteristics of long duration, high frequency, large coverage, and wide influence, which has seriously threatened the safe and stable operation of the power grid and the reliability of power supply. There are many factors that affect line icing. However, ordinary manual inspections or helicopter inspections cannot effectively solve the real-time monitoring of the icing status of cables, and once the high-voltage transmission lines are overly icing and cannot be effectively de-iced, the consequen...

AI Technical Summary

Problems solved by technology

However, ordinary manual inspections or helicopter inspections cannot effectively solve the real-time monitoring of cable icing conditions. Once the high-voltage transmission lines are over-iced and cannot be effectively de-iced, the consequences will be unimaginable.

[0003] However, in the existing technology, it is impossible to predict the possibility of icing in each area, resulting in a decrease in the accuracy of early warning
