IEEE P1159.3 Task Force IEEE Power & Energy Society Transmission & Distribution Committee http://grouper.ieee.org/groups/td/ Power Quality Subcommittee http://grouper.ieee.org/groups/td/pq/ P1159.3 PQDIF Task Force http://grouper.ieee.org/groups/1159//3 Chair: Daniel Sabin (d.sabin@ieee.org) Secretary: Rich Bingham (r.bingham@ieee.org) 4
What is IEEE PQDIF? PQDIF is defined in IEEE Std 1159.3-2003 a recommend practice for power quality data interchange format that allows exchange of measurements and simulation results between computer hardware and software systems PQDIF is a binary format that features optional lossless compression using zlib The initial standard was approved by IEEE RevCom in 2003 and was reaffirmed in 2008. With the ten-year lifecycle for IEEE standards, a revision must be completed by December 2018. 5
Recent Administrative Activity Although most of the working groups and tasks forces of the IEEE SCC-22 Standards Coordinating Committee were transferred to the IEEE PES Power Quality Subcommittee in July 2002, the IEEE P1159.3 Task Force was still under IEEE SCC-22. The IEEE P1159.3 Task Force was officially transferred from SCC-22 to IEEE PQ Subcommittee in March 2014. 6
PAR Application to IEEE New Standards Committee (NesCom) for P1159.3 Revision A Project Authorization Request (PAR) is the means by which standards projects are started within the IEEE-SA. PARs define the scope, purpose, and contact points for the new project. The task force submitted a PAR to NesCom on May 23, 2014 to revise IEEE Std. 1159.3. The PAR was approved at the August 21, 2014 meeting of NesCom in Beijing. The P1159.3 Task Force was set up as a working group when NesCom approved the PAR, and this is the name of the group in IEEE SA web site 1159.3 Working Group for Transfer of Power Quality Data The PAR was approved until December 2018, which is the same date when IEEE Std 1159.3-2003 would expire without revision. 7

Proposed Annex on Representation of PQDIF in XML 21
Feedback from CIGRÉ/CIRED Joint Working Group C4.112 on Power Quality Monitoring The industry needs a simple text file format to facilitate light implementations that cannot include a C++, COM, or.net Library. PQDIF is precise but requires a lot of expertise. Proposed Solution In addition to defining the verbose, complete representation of a PQDIF file in XML, we could define an XML representation of a PQDIF observation record with just enough information from the data source record and/or monitor settings records that would identify the monitor name (e.g., MyMonitor), channel definitions (e.g., RMS Voltage Phase A), and series definitions (e.g., Average) with a nominal base voltage of 12 kv and a nominal fundamental frequency of 50 Hz. 22
Proposed Annex on PQDIF s Relationship to IEC 61850 IEC 61850-8-1 defines file classes that can be mapped to the Manufacturing Message Specification (MMS) file object. PQDIF Files and COMTRADE Files, Other supported file types: bin, dtd, gif, htm, txt, xml, xsd, zip IEC TC57 and TC85 are collaborating on a new technical report: TR IEC 61850-90-17 If the recommendations of the report are adopted by IEC TC 57, a new logical node with the working title Continuous Power Quality recorder will be implemented in IEC 61850-7-4 Ed. 3 IEEE PQDIF Std. 1159.3-2003 is the preferred file format. A first draft of IEC TR 61850-90-17 Using IEC 61850 to transmit Power Quality data is available for comment (DC or Draft for Comment ). We need to provide feedback on the draft document We should incorporate a summary of the TR in our proposed annex to the revised IEEE Std. 1159.3 23
Feedback from Joint Working Group of IEC TC85/TC57 Add rapid voltage change (RVC) single-event characteristics and an RVC event list Add flagging to indicate when power quality disturbances occur to allow a given ten-minute value (e.g., 10-minute short-term flicker perception Pst) could be filtered because the 10-minute interval included a voltage sag. Only method available now: store single events or an event list of voltage sags, swells, etc., which indirectly can be used to know which 10-minute intervals should be filtered. However, many PQ monitors are not including events; they include a flag on each ten-minute interval. We do not have a place in a value log observation record for storing the flags. Proposal: Allow storage of an observation list that would be the timestamps of value logs that could be filtered. 24
Proposed Annex of PQDIF s Relationship to IEEE/IEC COMTRADE COMTRADE now has a dual IEEE/IEC logo The H26 Working Group in the Power Systems Working Group completed a COMTRADE conformity test plan document in December 2014. We plan to include an annex that compares PQDIF and COMTRADE Source material for the annex could draw on the IEEE Power Systems Relaying Committee Working Group H5C report on Common Data Format for IED Sampled Data Summarized PQDIF, COMTRADE, and 61850 Explained issues related to converting data between the formats 25
