Integrated data recording and analyzing device and COMTRADE (Common Format for Transient Data Exchange for Power System) split file method

Abstract

The invention discloses an integrated data recording and analyzing device and a COMTRADE (Common Format for Transient Data Exchange for power system) split file method. The integrated data recording and analyzing device comprises a collection unit and a management unit; the collection unit is a front-end device used for finishing functions of collection, analysis and primary storage of messages; and the management unit is a back-end device used for implementing functions of parameter and configuration management, offline analysis, secondary storage and the like. The COMTRADE split file method comprises the following steps of: 1), collecting a transient recorder, generating a split file and informing the management unit in a fault during a running time; 2), analyzing the fault by the management unit; 3), selecting a first fault element and executing a fourth step; 4), extracting the information of the fault element and storing the information as an HDR file of the split file; 5), extracting a fault analysis result and storing the result as an INF file of the split file; 6), extracting configuration information and storing the configuration information as a CFG file of the split file; and extracting information related to the fault element and storing the information as a DATA file of the split file; and 7), returning to the step 3). The integrated data recording and analyzing device and the COMTRADE split file method can improve the integration level of devices and simplify the configuration of substations.

Description

Technical field: [0001] The invention relates to the field of comprehensive automation of intelligent substations, in particular to an intelligent substation data recording and analysis device and a COMTRADE file division method integrating network message recording and fault recording functions. Background technique: [0002] The information exchange and sharing between smart substation equipment mainly adopts network messages. The health status of smart devices and communication networks directly affects the reliable operation of the entire substation. Therefore, it is necessary to record the communication messages of the entire smart substation. When the power system fails, it is not only necessary to record the original network message, but also to analyze and restore the network message to the fault waveform of the primary equipment of the power system and the record of the action behavior of the secondary equipment, so as to facilitate the analysis of the cause of the f...
