Abstract

The invention provides a power distribution network fault research and judgment post-analysis system and method. The system is characterized by comprising a fault brief report generation module, a fault disposal whole process time consumption statistics module, a fault electric quantity calculation module, and a fault research and judgment evaluation module, wherein the fault brief report generation module is used for extracting and summarizing key points of fault disposal to form a brief report; the fault disposal whole process time consumption statistics module is used for recording and analyzing each node change in the disposal process for each fault to obtain whole-process time consumption information; the fault electric quantity calculation module is used for calculating the power failure loss electric quantity and the advanced power recovery electric quantity of the fault; and the fault research and judgment evaluation module is used for evaluating faults from three aspects of terminal action, power distribution master station research and judgment and remote control execution.

Description

technical field [0001] The invention relates to the technical field of power system distribution automation, in particular to a post-event analysis system and method for fault research and judgment of a distribution network. Background technique [0002] Through the informatization transformation of the power system, it has been able to collect and save various data information during the operation of the power system, including fault case data. However, in the existing technology, due to problems such as data quality and multi-system interaction, which have an impact on the basic data of fault research and judgment, there is a deviation between the research conclusion and the actual fault situation. Therefore, a method that can accurately extract and Research and judge the program to realize the effective use of information, so as to achieve the real improvement and promotion of the distribution network system by informatization. Contents of the invention [0003] Aiming...
