Embodiment 1

[0023] Please refer to figure 1 and figure 2 , showing a power system fault diagnosis expert system provided by the present invention.

[0024] The power system fault diagnosis expert system includes a diagnosis system master station. In this embodiment, the diagnosis system master station is set directly by using the network of the dispatch master station (or the centralized control master station) (hereinafter collectively referred to as the dispatch master station).

[0025] figure 1 In the figure, the left side of the dashed line is the structure of the dispatching master station, and the right side of the dashed line is the diagnosis system master station of the fault diagnosis expert system.

[0026] Depend on figure 1 It can be known that the main station of the diagnosis system in this embodiment is hung in the network structure of the dispatching main station.

[0027] like figure 1 As shown, the corresponding dispatch master station may include: a dispatch mast...

Abstract

A power system real-time information calibration method, comprising: collecting panoramic information of the power system in real time; performing classification and calibration of information sources on the panoramic information; performing classification and calibration of the information types on the panoramic information; performing time condition calibration on the panoramic information Carry out information availability calibration on the panoramic information; classify and filter the fault diagnosis requirements of the panoramic information after the information source classification calibration, information type classification calibration, time condition calibration and information availability calibration, and the selected Panorama information participates in fault diagnosis as selected calibration information. The real-time information calibration method of the electric power system realizes the multi-dimensional calibration of the panoramic information, and then uses it for fault diagnosis, which can make the fault diagnosis more efficient and accurate.

Description

technical field [0001] The invention relates to the field of power system fault diagnosis, in particular to a real-time information calibration method of a power system. 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. [0004]...
