Abstract

The method for estimating the abnormal state of power system operation includes: creating a historical case library for expert diagnosis, the historical case library is divided into voltage level level, substation level and interval level, and each level has multiple level nodes; The data content of the historical cases is respectively filled in the hierarchical nodes corresponding to each level; in the historical case library, the operation state values ​​of the various types of disturbances before the occurrence of the disturbance are analyzed by big data, and the operation state of each operation state is calculated. The value of the disturbance warning threshold; real-time collection of panoramic information of the user grid; when a certain operating status value of the panoramic information exceeds its corresponding disturbance warning threshold, a disturbance warning is issued. The estimation method can provide the user with an estimation of the occurrence of the disturbance, and remind the user to take measures in time to prevent the occurrence of the disturbance.

Description

technical field

[0001] The invention relates to the field of power system fault diagnosis, in particular to a method for estimating abnormal state of power system operation. Background technique

[0002] The power system is a system formed by connecting many power stations, substations, distribution stations and users by transmission and distribution lines. It usually consists of generators, transformers, bus bars, transmission and distribution lines and electrical equipment. Various electrical components, equipment and systems are usually in normal operation, but may also malfunction or abnormally operate.

[0003] Power system failure refers to a state in which electrical components and equipment cannot work according to expected indicators, that is to say, electrical components and equipment fail to achieve the functions they should achieve. Faults include generator set faults, transformer faults, transmission line faults, Substation faults and busbar faults, etc. [0...
