A system and method for automatically generating analysis models of fault recording files

Abstract

The invention discloses a system and method for automatically generating an analysis model of a fault recording file. The system includes a data processing unit, a data extraction unit and a model library, wherein the model library stores CFG files and power grid model CIME files; The extraction unit automatically extracts the channel name of the CFG file and transmits it to the data processing unit. The data processing unit formats and divides the channel name to obtain a standardized name, and establishes a relationship model in combination with the channel type. The device parameter information in the file gets the DMF file. The invention automatically establishes a relationship model by comparing the channel type with the corresponding type in the library, and sequentially generates structures such as protection, switch, busbar, line, transformer, etc., which not only reduces the situation that the fault cannot be judged due to untimely update, but also improves the accuracy of model configuration. It can improve the accuracy of fault judgment and reduce the complexity and configuration time of manual configuration.

Description

technical field [0001] The invention relates to the field of power system data processing, in particular to a system and method for automatically generating analysis models of fault recording files. Background technique [0002] After a fault occurs in the power system, the substation-side protection and fault recording device will generate a common format file for power system transient data exchange (COMTRADE), which is used to record the transient waveform and accident data collected in the power system. The standard was proposed by IEEE in 1991 and revised in the same year. The last revision of the standard was published on July 31, 2017 as "GB / T14598.24-2017 Measuring Relays and Protective Devices Part 24: Power System Transient Data Exchange ( COMTRADE) Common Format". The format consists of five files: CFG, DAT, INF, HDR, and DMF. [0003] The CFG file is a configuration file, which is pre-determined according to the status of the device and generated in a standardi...

Problems solved by technology

[0010] In order to solve the above problems, the present invention proposes a system and method for automatically generating an analysis model of a fault recorder file. The present invention is based on a CFG file and a primary equipment model, from which the names of analog and switching channels are extracted and obtained by formatting the name and word segmentation After standardizing the name and comparing the channel type with the corresponding type in the model library, the associated model of the analog channel and the digital channel is established, and the primary equipment such as protection, switch, busbar, line, transformer, etc. When the fault cannot be judged, at the same time improve the accuracy of model configuration, improve the accuracy of fault judgment, and reduce the work complexity and configuration time of manual configuration
