Short-term prediction method and device for transmission line icing and storage medium

Abstract

The invention provides a short-term prediction method and device for transmission line icing and a storage medium. The short-term prediction method comprises the steps of obtaining meteorological information data and wire information data of a transmission line, wherein the meteorological information data comprises the temperature, humidity, precipitation and wind speed, and the wire information data comprises the current icing thickness and wire temperature of the wire; generating icing thickness prediction information of the transmission line by using an ARIMA (Autoregressive Integrated Moving Average) model and a neural network model according to the meteorological information data and the wire information data. According to the embodiment of the invention, whether the icing thickness of the transmission line exceeds the line load or not can be judged, and influences accumulated to an icing prediction result by errors existing in various measured microclimate factors of the existingicing prediction model are effectively reduced, thereby being conducive to arranging the duty, line inspection, ice melting or de-icing work, and improving the efficiency and quality of the de-icingwork.

Description

technical field [0001] The invention relates to the field of fault prediction of transmission lines, in particular to a short-term prediction method, device and storage medium for icing of transmission lines. Background technique [0002] Since the earliest recorded transmission line icing accident occurred in 1932, there have been some serious ice disasters at home and abroad. The production and life of residents caused huge economic losses. The power operation department urgently needs a fast and effective method for predicting icing on transmission lines, so as to reduce the damage rate of lines and towers and ensure the safe and stable operation of the power grid. [0003] It should be noted that the above introduction of the technical background is only for the convenience of a clear and complete description of the technical solution of the present invention, and for the convenience of understanding by those skilled in the art. It cannot be considered that the above t...
