Abstract

The invention relates to a regional pollution assessment method and system as well as an insulator pollution degree assessment method and system. A sampling point-based regional pollution assessment method comprises the steps of obtaining the concentration of each pollutant at a sampling point and the concentration of each pollutant at each value assessment point based on the sampling point; and calculating a pollution degree of each value assessment point according to a pollution degree of the sampling point, the concentration of each pollutant at the sampling point and the concentration of each pollutant at the value assessment point. According to the methods and systems, the influence of the pollutant concentration in a background environment on the pollution degrees of the sampling point and the value assessment point is effectively considered, so that accurate regional pollution assessment is realized while the pollution degree manual sampling work is reduced; and the sampling point-based regional pollution assessment method is applied to the insulator pollution degree assessment of a power transmission line, and the insulator pollution degree of a value assessment tower is calculated through the insulator pollution degree of a sampling tower, so that accurate insulator pollution degree assessment of the power transmission line is realized while the sampling work is reduced.

Description

technical field

[0001] The invention relates to the technical field of data analysis, in particular to a regional pollution assessment method and system, and an insulator pollution degree assessment method and system. Background technique

[0002] At present, there are many methods for evaluating the pollution degree of transmission line insulators, such as online monitoring using optical sensors, leakage current monitoring, and manual sampling of insulators. Among them, manual sampling of insulators: the method used to evaluate the pollution degree of insulators by measuring the salt density value and gray density value of the insulator surface is the most widely used because of its simple operation and accurate results. However, the pollution degree of each sampling insulator can only accurately represent the pollution degree of the insulator of the tower where the sampling insulator is located, and the pollution degree of the insulators of other towers of the transmission...
