Abstract

The invention discloses a responsibility division comprehensive analysis method and system for source network load power failure users, and relates to the technical field of power system application,and the method comprises the following steps: step 1, acquiring actual power parameters including line voltage U and user current I at rated frequency, and acquiring position distribution between power supply lines, user rated current and management capacity; 2, performing topology analysis on the position distribution among the power supply lines to obtain a main line and user branch lines; 3, carrying out the power fault judgment of the current line at a rated frequency; and step 4, analyzing and confirming responsible users causing faults in the fault users who are powered off within the influence range of the fault line. According to the technical scheme, the responsibility division analysis efficiency of the source network load power failure users is improved, the manual troubleshooting time and the consumption of manpower and material resources are saved, enterprises are helped to directly locate the responsibility users, and the economical efficiency and the safety in failure analysis are improved.

Description

technical field [0001] The disclosure of the present invention relates to the field of electric power system application technology, and in particular to a comprehensive analysis method and system for user responsibility division for power faults of source, network and load. Background technique [0002] The research on the cause analysis method of power failure has been carried out for many years, but most of these related researches are only at the theoretical level, the scene simulation is too ideal, ignoring the limitations of hardware acquisition equipment and the rapid changes in the environment The impact is very different from the actual situation on site. It cannot conveniently locate responsible users and cannot be put into practical use. Design an analysis object that is easy to select and equipped with various professional algorithms such as load rate analysis and power supply capacity. Analysis, load identification analysis, etc., rapid analysis of accident data...
