Method and system for monitoring concentration of power grid pollutant based on satellite remote sensing

Abstract

The invention discloses a method and a system for monitoring the concentration of a power grid pollutant based on satellite remote sensing. An environmental satellite carries an atmospheric trace gas differential absorption spectrometer, and a power grid area is divided into a plurality of target areas according to the monitoring range of atmospheric pollutants; remote sensing detection on a target area is performed by using the atmospheric trace gas differential absorption spectrometer to obtain an atmospheric extinction effect; the atmospheric extinction effect is transmitted to the ground in real time; the concentration of each electric power pollution component is processed and obtained according to the atmospheric extinction effect; the ground is divided into a plurality of grids with equal areas, and the vectorized data are output according to the concentration of the power pollution components; and the superposition analysis on the vectorized data and the power grid GIS is performed to obtain the air pollutant concentration. According to the method, each target area can be remotely sensed and detected in a high frequency and large range, each power pollution component can be accurately analyzed through the atmospheric extinction effect data, the quasi-real-time monitoring of the spatial distribution of each pollutant of the power grid is achieved, the data acquisition process is objective and stable, and the efficiency is high.

Description

technical field [0001] The present application relates to the technical field of power grid pollution monitoring, in particular to a method and system for monitoring the concentration of pollutants in a power grid based on satellite remote sensing. Background technique [0002] In recent years, the power transmission and transformation equipment of the power grid is often affected by various natural disasters, especially when there are a large number of heavily polluting enterprises around, resulting in heavy air pollution. Excessive power pollution will lead to accelerated aging of insulation devices, or even failure, causing Discharge on the outer surface of power transmission and transformation equipment causes line tripping and affects the reliable operation of the power grid. Therefore, effective monitoring of the pollution status of power transmission and transformation equipment in the power grid is the focus of current research. [0003] For power pollution monitori...
