IEEE 1159.3 PQDIF Task Force
IEEE Std 1159.3-2019 was published on 2019 May 1 and is valid until 2029.
This is IEEE's recommended practice for exchanging data between monitors and software using IEEE Power Quality Data Interchange Format (PQDIF).
IEEE Std 1159.3-2003 provided the industry with the first specification for PQDIF and was valid for five years. It was reaffirmed in 2009.
Between 2014 and 2018, the IEEE P1159.3 Task Force completed the following changes to IEEE 1159.3:
- Changed the title to "Recommended Practice for Power Quality Data Interchange Format (PQDIF)"
- Completed editorial changes and corrections to the 2003 edition of IEEE 1159.3
- Added new ID values for existing PQDIF tags in normative Annex B
- Added new tags and ID values in normative Annex B
- Added new quantity types in normative Annex B
- Added examples for storing event lists of voltage sags, transients, and rapid voltage change (RVC) events
- Updated Annex C.1, which specifies an INI file method for describing data source name, PQDIF location, and monitor properties
- Added an informative Annex C.2, which specifies an XML directory for PQDIF files that can be downloaded from a remote power quality monitor or remote file server
- Added an informative Annex D on the representation of PQDIF in XML
- Added an informative Annex E on PQDIF and its relationship to IEEE C37.111 COMTRADE
- Added an informative Annex F on PQDIF and its relationship to IEC 61850
The physical structure of PQDIF remains unchanged between IEEE Std 1159.3-2003 (2008) and IEEE Std 1159.3-2019,
making PQDIF both backward and forwards compatible. Changes to the logical structure to support new capability are
in the form of additional tag and ID values. This allows software that reads PQDIF to maintain compatibility
by simply ignoring unrecognized tag and ID values.
IEEE Std 1159.3-2019 is available for purchase from the IEEE Standards website.
Recommended Practice for Power Quality Data Interchange Format (PQDIF)
IEEE 1159.3 provides the power quality industry with the specification for PQDIF, which is an open and accepted data format standard for the transfer
of power quality data between instruments and computers. This transfer standard allows the processing and analysis of power quality measurements
using multi-vendor and multi-device data. Wider acceptance of PQDIF as a power quality data transfer format will significantly add to the value
of power quality monitoring and open new opportunities for the resolution, planning, and understanding of power quality activities.
Being able to exchange data between software systems will allow other functions needed in a power quality monitoring campaign, including validation,
trending, comparison, overlay, and more.
