Description

technical field [0001] The invention belongs to the technical field of line loss management, and in particular relates to an evaluation method based on the research on intelligent identification and tracking technology of specially variable user load. Background technique [0002] In recent years, the consumption of electric energy has been increasing steadily. The continuous development of renewable energy technology is accompanied by the rising proportion of its power generation in the total power generation. However, non-renewable energy power generation methods such as thermal power still occupy an absolute dominant position. Problems such as environmental pollution and resource supply are still serious. At the same time, the contradiction between the unbalanced development of renewable energy itself is gradually revealed: the huge increase in renewable energy consumption does not match the growth rate of electricity consumption in the same period. The installed capacit...

Problems solved by technology

[0005] In order to solve the problem of extracting the waveform of electrical equipment in real time from the collected bus load curve in the prior art, the load curve can be effectively analyzed after eliminating interference and noise, but there are great differences in the interference sources of variable loads in different scenarios , and the interference factor is not single, there will be multiple factors. The present invention analyzes the centralized scenarios one by one, thereby providing an evaluation method based on the research of intelligent identification and tracking technology of specific variable user load
