Abstract

The invention discloses an evaluation method based on special transformer user load intelligent identification and tracking technology research, and the method comprises the following steps: 1, starting from a collected special transformer user load waveform curve, taking the collected bus voltage, current and time as analysis objects, and carrying out the analysis; accurately extracting a load curve of each operated device by utilizing an extraction and association method; 2, comparing advantages and disadvantages of different elimination methods by researching the different elimination methods, and determining an interference source elimination method suitable for the load of the special transformer user; 3, carrying out the research of a load identification method, comparing the differences of different mapping identification methods, and determining an identification method with a higher mapping identification rate with the waveform space-time database; and 4, based on the equipment type of the equipment, analyzing key characteristic quantities of a transient process, a steady state process, a fluctuation period, harmonic analysis and a random periodic component of certain load equipment in different states from multiple angles, and further judging the state of the load equipment.

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...
