Problems solved by technology

[0003] To carry out clean energy dispatching and operation, it is first necessary to understand the real situation of haze pollution and the subsequent change trend. At present, ground observation methods are mostly used to analyze the occurrence and movement of haze. However, due to scattered observations, the overall pollution trend cannot be grasped. difficulty

Embodiment 1

[0038] see figure 1 , the present embodiment provides a method for analyzing movement of smog based on satellite monitoring, comprising the following steps:

[0039] S1: Divide the area to be monitored into grids, select at least two adjacent grids to form a basic area, and form sub-areas according to the size of the basic area;

[0040] S2: Use satellites to monitor each grid at least twice within a set period of time, and calculate the aerosol optical depth value of each grid area at each monitoring moment;

[0041] S3: Construct the aerosol optical depth sequence of the basic region according to the aerosol optical thickness value in the grid of the basic region, and construct the aerosol optical depth of each subregion according to the aerosol optical thickness value in the grid of each subregion sequence, calculate the correlation between each sub-region and the basic region according to the aerosol optical depth sequence of the sub-region at the later monitoring time an...

Abstract

The invention relates to the technical field of power distribution, and discloses a method and a system for analyzing a haze movement based on satellite monitoring, so as to realizing the effective analysis for the haze movement, thereby knowing the pollution caused by the haze quickly and accurately. The method comprises the following steps: performing grid division on a region to be monitored; selecting at least two adjacent grids to form a basic region, and forming the rest of the grids into sub-regions according to the size of the basic region; adopting a satellite to monitor each grid forat least two times within a set period; calculating an optical thickness value of an aerosol of each grid region at each monitoring moment; calculating the correlation between each sub-region and thebasic region according to the optical thickness sequence of the aerosol of the sub-region at a front monitoring moment and the optical thickness sequence of the aerosol of the sub-region at a rear monitoring moment to obtain a sub-region which has the largest correlation with the basic region; and obtaining the haze movement condition of the region to be analyzed.

Description

technical field [0001] The invention relates to the field of power distribution technology, in particular to a method and system for analyzing smog movement based on satellite monitoring. Background technique [0002] In recent years, smog incidents have occurred frequently, and people's living and ecological environment have gradually deteriorated, seriously affecting people's production and life, as well as physical and mental health. With the continuous improvement of my country's power grid construction, electric energy is gradually replacing polluting energy such as coal as a clean energy, and can effectively improve air quality problems during periods of high smog. [0003] To carry out clean energy dispatching and operation, it is first necessary to understand the real situation of haze pollution and the subsequent change trend. At present, ground observation methods are mostly used to analyze the occurrence and movement of haze. However, due to scattered observations...
