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 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.
