Problems solved by technology
In the process of rapid and steady increase in pollution, due to the continuous accumulation of pollution, even with the same meteorological and topographical conditions, the degree of pollution is different at different times, but according to the traditional forecasting method, using the same meteorological, topographical and other parameters, the result obtained is Again, this tends to produce large errors

Embodiment Construction
[0029] The realization of the pollution acceleration model under wildfire conditions mainly comes from the following three theories and methods:
[0030] 1. Fuzzy mathematics theory
[0031] Professor L.A. Zadeh established fuzzy set theory in 1965, which expanded the research field of classical mathematics and brought about major changes in the entire mathematics research system. The theoretical method of fuzzy mathematics can effectively solve the complexity problems of large systems that are difficult to solve by classical mathematics, as well as the fuzzy problems that are ubiquitous in nature and daily life and cannot be solved.
[0032] Set is one of the most basic concepts in the history of modern mathematics. The classic set representation methods include enumeration and description. They can only describe concepts with clear extensions, and the objects are either one or the other. There is no way to describe some vague concepts. , such as "body fat and thin", since t...

The invention provides a method for predicting the pollution degree of a transmission line after a wildfire occurs, and belongs to the field of electric power system and data mining. The invention realizes the classification of different pollution accumulation processes after wildfires occur, and on this basis, according to the mechanism of pollution accumulation, a more accurate pollution prediction model is established, that is, the membership degree of different pollution accumulation processes at the current prediction time is introduced As one of the impact factors, compared with traditional forecasting methods, it is more in line with the actual situation and the results are more reliable. The invention provides a tool for quickly predicting the pollution degree of the transmission line after a wildfire occurs, and provides a guarantee for preventing accidents caused by the pollution of the transmission line. , to assist in the management of transmission lines.
Description
technical field [0001] The invention relates to the field of disaster reduction and prevention in electric power systems, in particular to a method for predicting the pollution degree of transmission lines after wildfires occur. Background technique [0002] When the existing pollution regression prediction model predicts the pollution degree at a certain time, the meteorological data and terrain data at that time are used as parameters to obtain the pollution degree through the mapping relationship. This method focuses more on the mapping relationship and does not take into account the specific conditions of pollution accumulation. , in fact, this approach is limited in view of the actual accumulation process of contamination. [0003] When the wildfire occurred and just after it occurred, the pollution had a process of rapid and steady increase until the pollution remained at a certain value and only fluctuated within a small range. In the process of rapid and steady incr...
