This section GB/T 14598 Part 24.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section instead of GB/T 22386-2008 "power system transient data exchange common format", compared with GB/T 22386-2008, the main technical differences.

--- The new version allows the use of a single file format (with. CFF suffix) file instead of four separate files;

A single file with a .CFF suffix contains 4 partitions, corresponding to .CFG, .INF, .HDR, and .DAT, respectively. DAT partition both can be ASCII format can also be Binary format;

--- Support binary32 and float32 data types;

---. CFG file format revision. The end of the .CFG added time-related two lines of a total of four domain content;

---. CFG part of the file can be amended as a mandatory option;

--- Added UnicodeUTF-8 format support.

This section uses the translation method identical with IEC 60255-24:2013 "Measuring relays and protection devices Part 24. Power System temporarily Common Format Data Exchange (COMTRADE) "(in English).

Introduction

With the rapid development of the application of digital technology, various protection, recording, measuring and controlling equipment of substation in the transient event of power system Will accumulate a large number of digital records. In addition, analog and digital power system simulations produce digital records as well. The use of these records are facing the problem of handling different data formats generated, stored and transmitted by various systems.

Measuring relays and protection devices Part 24. Power system transient data Exchange (COMTRADE) common format

1 Scope

This section GB/T 14598 defines a file format that applies to contain the transient obtained from the power system or power system model Waveform and event data files. This section provides an easy-to-interpret data exchange format suitable for storage in a variety of current applications Files on physical media, such as removable media, USB storage, flash memory, CDs and DVDs. This section does not communicate through the Internet format.

This section GB/T 14598 defines a common exchange format for a variety of fault, test and simulation data files and Exchange media. With the continuous development and application of fault and transient digital data recording and testing in the power industry, a data exchange the standard format of the demand. The application of these data will improve the analysis of the power system and its protection control measures in case of disturbance, Testing, evaluation and simulation of the automation level. Because each data source may use a different proprietary format, define a can promote these data A common format for switching between different devices is necessary, which facilitates the exchange and use of private data between different applications and also permits private the system uses data from other systems.
