Embodiment

[0041] Such as figure 1 As shown, this embodiment includes the following steps:

[0042] 1) Standardize the information model file of the fault wave recording device, establish the power transmission system model configuration file, that is, the INF model file, use XML file as the storage format of the model file, and establish its standardized file structure with XML Schema, for automatic modeling Provide a unified configuration template;

[0043] 2) Load the model configuration template, import the substation model library, import the CFG configuration file, provide the model configuration template editing interface, add a mapping relationship between equipment and channels, and generate an INF model file;

[0044] 3) The fault recording device loads the INF model file generated in step 2), and when a fault occurs, the dispatcher obtains a fault notification, and obtains the CFG configuration file generated online and the DAT data file generated online from the fault record...

Abstract

A record wave pattern modeling method for a fault record device of an intelligent transformer substation belongs to the technical field of power supply systems, builds pattern configuration files by standardizing information pattern files of fault record wave equipment to supply uniform configuration patterns for automatic pattern building and generates intermediate-range nuclear forces (INF) patter files. When fault happens, a scheduling end acquires fault nitrification to obtain the fault record wave files containing control flow graph (CFG) configuration files generated in online mode, digital audio tape data files generated in online mode and INF pattern files from the fault record device, and the pattern information is utilized to extract channel information for multiple stations, multiple device and multiple files according to the same system fault to form virtual record wave files containing complete information of the fault. The record wave pattern modeling method for the fault record device of the intelligent transformer substation achieves treatment of a plurality of automatic fault record wave data based on storage and transmission of distributed type record wave pattern files of a transformer substation at the scheduling end, thereby greatly improving efficiency of fault diagnosis and fault analysis of power grids.

Description

technical field [0001] The invention relates to a method in the technical field of power systems, in particular to a wave recording model modeling method for a fault wave recording device of an intelligent substation. Background technique [0002] When a fault or a large disturbance occurs in the power grid, both the centralized fault recording device and the protection device with the recording function (hereinafter collectively referred to as the fault recording device) can accurately record the recording data of several cycles before and after the fault. Compared with event (Event) information, fault recording data has many unique advantages, for example: (1) High reliability. The sampling frequency of the fault recorder can generally reach 4kHz and above, which contains more abundant transient information of the power grid, and can truly reflect the operation of the power grid before and after the fault; (2) Good fault tolerance. Since the fault recording device can rec...
