Abstract

The present application discloses a method and system for monitoring the concentration of power grid pollutants based on satellite remote sensing. The environmental satellite is equipped with an atmospheric trace gas differential absorption spectrometer, and the power grid area is divided into multiple target areas according to the scope of atmospheric pollutant monitoring; The atmospheric extinction effect is obtained by remote sensing detection of the target area using a differential gas absorption spectrometer; the atmospheric extinction effect is transmitted to the ground in real time; the concentration of each power pollution component is processed according to the atmospheric extinction effect; the ground is divided into several equal-area nets Grid, the concentration of power pollution components is output vectorized data according to the grid; the vectorized data is superimposed and analyzed with the power grid GIS to obtain the air pollutant concentration. The application can detect various target areas with high-frequency and large-scale remote sensing. Through the atmospheric extinction effect data, the pollution components of each power can be accurately analyzed, and the quasi-real-time monitoring of the spatial distribution of various pollutants in the power grid can be realized. 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...
