Automatic generation system and method of fault recorder file analysis model

Abstract

The invention discloses an automatic generation system and method of a fault recorder file analysis model. The system comprises a data processing unit, a data extraction unit and a model base, whereinthe a CFG (configuration) file and a grid model CIME (common information model specification) file are stored in the model base; the data extraction unit extracts a channel name of the CFG file automatically and transmits it to the data processing unit, the data processing unit formats the channel name and performs word segmentation to obtain a standardized name, a relationship model is established in conjunction with channel type to generate primary devices, and a DMF (distribution media format) file is acquired in conjunction with device parameter information in the CIME file. The channel type is compared with corresponding types in the base to automatically establish the relationship model, protection, switches, busbar, circuitry, transformers and other structures are generated in sequence, chances for judging failure of faults due to not-in-time updating can be slimmed, model configuration accuracy is improved, fault judging precision is improved, and work complexity of manual configuration is relieved with configuration time thereof shortened.

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
