Foreword
This is equivalent to using the standard IEC 60255-24.2001 "General Power System Transient Data Exchange Format" (in English), equivalent translation
IEC 60255-24.2001.
During the drafting process, the present standard made the following editorial changes.
a) "this International Standard" be replaced by "this standard";
b) use a decimal point instead of a decimal comma ",". ",";
c) Remove the preface to international standards;
d) Correction section 2.3 "ANSI/IEEEstandard" as "IEC 60044-1";
e) Correction in Section 7.9.2 "CB" is "CG";
f) for national standards and inconsistencies "phase voltage 70V", "345kV" add note etc., will be described;
g) of the original text some obvious typographical errors have been corrected or explained.

Introduction
This standard specifies the general format of the data files, and various types of faults, test and simulation data interchange needed a medium of exchange.
Fault transient data recording and digital devices as well as rapid development and the achievement test in the power industry, the proposed data exchange format standard
Normalized requirements. Various devices and the use of power system fault transient data, enhanced fault and disturbance conditions, and on the protection of the grid configuration
Analysis, testing, evaluation and simulation and automate. Since each of the data sources may use different proprietary data formats, so that, in order to facilitate
The data exchange between applications, a common data format standard is necessary. This facilitates dedicated data in a variety of applications so that
Use, and allow the user to use a dedicated digital system data from other systems.

Power system transient common format for data exchange
1 Scope
This standard specifies the format of the file. This file contains the power system or power system model to collect transient waveforms and events
Pieces of data. This standard applies to files stored on physical media, such as digital files stored on the hard disk and floppy disks. This standard is not a
On the standard communications network to transmit data files that it intends to exchange data applications, providing an easy explanation of the format, and the format itself is not
There utilizing proprietary format encodes data depends competitive advantage and compression brings economy.
2 Terms and definitions
The following terms and definitions apply to this standard.
2.1
In a series of binary data bits stored in the file.
Note. Each can be "1" or "0." These bits are organized in eight groups, called bytes. When the computer reads the file data to a series of bytes read.
2.1.1
Organized in bytes of data.
Note. The 8-bit byte can form 256 different combinations of numbers from 0 to 255 can be expressed. To indicate a greater number of available number of bytes, for example,
2 bytes (16 bits) between 0 to 65535 may represent. When the byte in such a form of explanation, they will be referred to as binary data. Binary
Digital data is often stored in many different forms.
2.1.2
Match 127 kinds of combinations of symbols 8 binary bits.
NOTE. As the number of bytes representing 0 to 255 represents another method, a byte can be used to represent 255 different symbols. American National Standard for Information Interchange
Codes are 127 kinds of matching 8-bit binary combinations list of symbols, such as the byte 01000001 represents capital letter "A", and 01,100,001
It indicates lowercase "a". 127 kinds of different combinations, can represent all the keys and many other special symbols on the keyboard. The remaining portion 8 256 kinds of combinations
Mapping and other application-specific character used to represent points. ASCII representation in the form of a number, each digit of the number to be represented by a byte.
2.2
Some data in the configuration file for the sample data reproduction is not essential; some variables in the configuration file may not be associated with a particular application
Very relevant. So some of the data can be called optional data can be omitted. Channel recording device name is an example of the data available. however,
In order to maintain the integrity of the file, the general should be kept optional variable position occupied. If any of the data in this section is described as an optional number
It can be reserved its position that immediately before a data separator, with no intervening characters or spaces, add a space character and corresponding data separator.
Sampling data necessary for reproducing the data referred to the necessary data. If the lack of necessary data, the file may be unavailable.
2.3
Means for measuring and recording high-voltage grid event can not be directly collected grid high voltage and high current. These devices can be connected in accordance with
That is easy to handle, the lower the level of danger, known as the second volume of manufactured inputs. Voltage and current transformer to reduce from the grid
Voltage and current signals, so as to achieve a level suitable for the installation process. Select the transformer ratio, make the grid run rated, ie a nominal value
