Embodiment

[0024] refer to figure 1 and figure 2 , the present embodiment provides a power fault intelligent analysis and inversion system, including: a time stamp identification module 1, a synchronization module 2, an integration module 3, a file generation module, a fault intelligent analysis module 5, an accident inversion module 6, and a fault location Module 7, sequential logic module 8 and human-computer interaction module 9.

[0025] The panorama information platform includes wave recorder, process layer network analyzer, station control layer message and telecontrol system. The faults and wave recording information uploaded by the panorama information platform pass through time stamp identification module 1, synchronization module 2 and integration module 3 in sequence, Arrange and graphically display these fault information in an orderly manner from the time axis, and restore the information of the entire fault system.

[0026] The file generation module includes a CFG file ...

Abstract

The invention provides a power fault intelligent analysis and inversion system and method, and the method comprises the steps: carrying out the ordered arrangement and graphic display of fault information on a time axis; restoring the information of the whole fault system; enabling a file generation module to form a CFG file, a DAT file, a DMF file and an HDR file through the restored information, thereby forming a COMTRADE file, wherein the file generation module, a fault intelligent analysis module, an accident reversion module, a fault positioning module, a time sequence logic module and a man-machine interaction module are connected sequentially; sequentially carrying out the fault intelligent analysis, accident reversion, fault positioning and time sequence editing according to the files generated by the file generation module; and transmitting a fault diagnosis result to an operator through the man-machine interaction module. Therefore, the method solves problems that the relay protection fault analysis data is scattered in different and relatively independent systems and there is currently no complete system for integrating the data collected by independent systems. The invention belongs to the field of power systems.

Description

technical field [0001] The invention relates to an analysis and inversion system and method, belonging to the field of power failure analysis. Background technique [0002] With the rapid development of power grid automation technology, the functions and performance of the power grid automation system have been continuously improved, and the degree of automation of power operation management has reached a very high level. Various microcomputer relay protection, fault recorder and other equipment and safety automatic devices in the substation can record and upload various relay protection information in real time, and provide the required data for the fault analysis of the power grid. Correspondingly, a large amount of information generated by these devices lacks unified and effective management, and the automation level of the monitoring of relay protection information, analysis and management of system faults and protection actions appears to be relatively lagging behind. ...
