Introduction This introduction is not part of IEEE Std C37.118.2-2011, IEEE Standard for Synchrophasor Data Transfer for Power Systems. Digital computer based

3、measurement, protection, and control systems have become common features of electric power systems. These measurement, protection, and control systems use sampled data to compute various quantities such as voltage and current phasors. Phasors are used in many protection and data acquisition function

4、s, and their utility is increased further by referencing them to a common time base. This can be accomplished by synchronizing the phasor estimate to a precise time source that is common to the various measuring sites. Phasor estimates synchronized to a common time source and referenced to a common

5、nominal frequency are defined as synchrophasors. Simultaneous measurement sets derived from synchronized phasors provide a vastly improved method for tracking power system dynamic phenomena for improved power system monitoring, protection, operation, and control. The original standard for synchropha

6、sors was IEEE Std 1344-1995 B3, which was reaffirmed in 2001.a This standard was replaced in 2005 by IEEE Std C37.118-2005 B6. IEEE Std C37.118-2005 provided additional clarification for the phasor and synchronized phasor definitions. The concepts of total vector error and compliance tests were intr

7、oduced. The message formats were updated from the original standard to improve information exchange with other systems such as a master station. Specifically, the sync, frame size, and station identification fields were added to the data frame, configuration frame, header frame, and command frame. A

8、nalog data was added to the data frame, the fraction-of-second (FRACSEC) field replaced the sample count field, and the status field was significantly modified to include time quality. The 2005 version of IEEE Std C37.118 included both measurement requirements and real-time data transfer requirement

9、s. To simplify widespread adoption and facilitate the use of other communication protocols for phasor data transfer, IEEE Std C37.118-2005 B6 was split into two standards: IEEE Std C37.118.1 for synchrophasor measurement requirements including dynamic performance, and IEEE Std C37.118.2-2011 (this s

10、tandard) with synchrophasor data transfer requirements.bThe previous requirements for data transfer are retained, and one new configuration frame has been added.

Overview 1.1 Scope This standard defines a method for exchange of synchronized phasor measurement data between power system equipment. It specifi

38、es messaging including types, use, contents, and data formats for real-time communication between phasor measurement units (PMU), phasor data concentrators (PDC), and other applications. 1.2 Purpose The purpose for this standard is to facilitate data exchange among measurement, data collection, and

39、application equipment. It provides a defined, open access method for all vendors to use to facilitate development and use of synchrophasors. It is a simple and direct method of data transmission and accretion within a phasor measurement system, which may be used directly or with other communication

40、protocols. This method was initially established by IEEE Std C37.118-2005 B6.11The numbers in brackets correspond to those of the bibliography in Annex A. 1 Copyright 2011 IEEE. All rights reserved. IEEE Std C37.118.2-2011 IEEE Standard for Synchrophasor Data Transfer for Power Systems 1.3 General o

41、verview This standard defines data transmission formats for real-time data reporting for synchronized phasor measurements used in electric power systems. Clause 1 provides the scope and need for the standard. Clause 2 references other standards that are related or may be useful in the study and appl

42、ication of this standard. Clause 3 defines terms, acronyms, and abbreviations found in this standard. Clause 4 provides background for synchrophasor measurement. Clause 5 describes synchrophasor measurement system. Clause 6 defines the real-time communication protocol and message formats. Six inform

43、ative annexes are provided to clarify the standard and give supporting information: Annex A is a bibliography. Annex B gives information about cyclic redundancy codes and the cyclic redundancy check (CRC) required by this standard. Annex C provides background in communication bandwidth. Annex D illu

44、strates the message formats defined in Clause 6 with complete message examples. Annex E defines message mapping into standard communication protocols. Annex F discusses synchrophasor communications methods for Internet Protocol (IP). 1.4 Need for this standard The 2005 version of IEEE Std C37.118 in

45、cludes both measurement requirements and real-time data transfer requirements. To simplify widespread adoption of synchrophasor measurement technology and facilitate the use of other communication protocols for phasor data transmission, IEEE Std C37.118-2005 B6 was split into two standards, one with

46、 measurement requirements and the other with the data transfer requirements. This allows other communication protocols and systems to be used with phasor measurement systems supporting the original purpose of the standard. This split facilitates harmonization of IEEE Std C37.118-2005 with IEC 61850.

47、 This standard includes only the data transfer portion of IEEE Std C37.118-2005, adding some corrections and improvements yet retaining the current messaging for backward compatibility. This approach supports the widely used method for current and developing deployments, and allows for a smooth tran

48、sition of synchrophasor systems to new protocols as needed. 2 Copyright 2011 IEEE. All rights reserved. IEEE Std C37.118.2-2011 IEEE Standard for Synchrophasor Data Transfer for Power Systems 2.
