    1、 IEC 60255-24 Edition 2.0 2013-04 INTERNATIONAL STANDARD Measuring relays and protection equipment Part 24: Common format for transient data exchange (COMTRADE) for power systems IEC 60255-24:2013IEEE Std.C37.111-2013IEEE Std C37.111colourinsideTHIS PUBLICATION IS COPYRIGHT PROTECTED Copyright 2013

    2、IEEE All rights reserved. IEEE is a registered trademark in the U.S. Patent any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparat

    3、ion. IEEE Standards documents are developed within IEEE Societies and Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which bring

    4、s together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members of IEEE and serve without compensation. While IEEE administers the process and establishes rules to promote fairness in the consensus development process, IEEE does

    5、 not independently evaluate, test, or verify the accuracy of any of the information contained in its standards. Use of IEEE Standards documents is wholly voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers (see http:/standards.ieee.org/IPR/disclaim

    6、ers.html for more information). IEC collaborates closely with IEEE in accordance with conditions determined by agreement between the two organizations. This Dual Logo International Standard was originally an IEEE standard that was adopted by the IEC and has been jointly revised by the IEC and IEEE u

    7、nder the terms of that agreement. 2) The formal decisions of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. The formal decisions of

    8、IEEE on technical matters, once consensus within IEEE Societies and Standards Coordinating Committees has been reached, is determined by a balanced ballot of materially interested parties who indicate interest in reviewing the proposed standard. Final approval of the IEEE standards document is given

    9、 by the IEEE Standards Association (IEEE-SA) Standards Board. 3) IEC/IEEE Publications have the form of recommendations for international use and are accepted by IEC National Committees/IEEE Societies in that sense. While all reasonable efforts are made to ensure that the technical content of IEC/IE

    10、EE Publications is accurate, IEC or IEEE cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications (including IEC/IEEE Publications) transpar

    11、ently to the maximum extent possible in their national and regional publications. Any divergence between any IEC/IEEE Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC and IEEE do not provide any attestation of conformity. Independent

    12、 certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC and IEEE are not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7)

    13、No liability shall attach to IEC or IEEE or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees, or volunteers of IEEE Societies and the Standards Coordinating Committees of the IEEE Standards Association (IEEE

    14、-SA) Standards Board, for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC/IEEE Publication or any other IEC or IEEE Publicati

    15、ons. 8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that implementation of this IEC/IEEE Publication may require use of material

    16、 covered by patent rights. By publication of this standard, no position is taken with respect to the existence or validity of any patent rights in connection therewith. IEC or IEEE shall not be held responsible for identifying Essential Patent Claims for which a license may be required, for conducti

    17、ng inquiries into the legal validity or scope of Patent Claims or determining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance, if any, or in any licensing agreements are reasonable or non-discriminatory. Users of this standard are expressly a

    18、dvised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. 6 IEC 60255-24:2013 IEEE Std C37.111-2013 Published by IEC under license from IEEE. 2013 IEEE.

    19、EEE Std C37.111 has been jointly revised by the Power System Relaying Committee of the IEEE Power and Energy Society1in cooperation with IEC Technical Committee 95: Measuring relays and protection equipment, under the IEC/IEEE Dual Logo Agreement. This second edition cancels and replaces the first e

    20、dition published in 2001 and constitutes a technical revision. The main changes with respect to the previous edition are as follows: a) The new edition allows single file format (with extension .CFF) in lieu of four separate files. b) The single file with .CFF extension contains four sections of inf

    21、ormation corresponding to .CFG, .INF, .HDR, and .DAT. The DAT section is either in ASCII or Binary. c) The following additional data file types are also supported: binary32 (using 4 bytes to represent integer numbers) and float32 (using 4 bytes to represent real numbers). d) g55g75g72g3g70g82g81g191

Two fields repres

INTRODUCTION The increasing use of digital technology in devices such as protection, oscillograph, measurement, and control apparatus in electric power substations has cr

    30、eated the potential for accumulating large numbers of digital records of power system transient events. In addition to these sources of digital data, analog and digital power-system simulators may be used to generate digital records. The users of these records are faced with the problem of having to

    31、 cope with different formats used by each system to generate, store, and transmit records. 8 IEC 60255-24:2013 IEEE Std C37.111-2013 Published by IEC under license from IEEE. 2013 IEEE. All rights reserved. MEASURING RELAYS AND PROTECTION EQUIPMENT Part 24: Common format for transient data exchange

    32、(COMTRADE) for power systems 1 Scope This International Standard defines a format for files containing transient waveform and event data collected from power systems or power system models. The format is intended to provide an easily interpretable form for use in exchanging data. The standard is for

    33、 files stored on currently used physical media such as portable external hard drives, USB drives, flash drives, CD, and DVD. It is not a standard for transferring data files over communication networks. This standard defines a common format for the data files and exchange medium needed for the inter

    34、change of various types of fault, test, and simulation data. The rapid evolution and implementation of digital devices for fault and transient data recording and testing in the electric utility industry have generated the need for a standard format for the exchange of time sequence data. These data

    35、are being used with various devices to enhance and automate the analysis, testing, evaluation, and simulation of power systems and related protection schemes during fault and disturbance conditions. Since each source of data may use a different proprietary format, a common data format is necessary t

    36、o facilitate the exchange of such data between applications. This will facilitate the use of proprietary data in diverse applications and allow users of one proprietary system to use digital data from other systems. 2 Normative references IEEE Std C37.118TM-2005, IEEE Standard for Synchrophasors for
