I1: Understanding Microprocessor-Based Technology Applied to Relaying
Chair: M.S. Sachdev
Vice-Chair: Ratan Das
Output:
PSRC Report
The Working Group did not meet in January 2009 during the joint technical meetings of the PES Committees in Atlanta.
After the September meeting of the PSRC, the Chair received comments from the PSRC Chair suggesting some changes in the WG document.  The suggested changes did not change the intent of the document.  It took two iterations to make the changes that satisfied the PSRC Chair.  The modified draft was then circulated to the WG and Subcommittee members for comments of substance.  The WG document is ready and a copy has been given the I Subcommittee Chair for posting on the Subcommittee website.  Another copy has been sent to Russ Peterson for posting on the PSRC web site.
The WG has completed its task and it is recommended that the WG be disbanded.
The SC disbanded the WG with thanks to the Chair and all members for their contributions.
I2: Terminology Usage Review
Chair: M. J. Swanson
Vice-Chair: Barb Anderson
Output:
Definitions for C37.100 and IEEE Std. 100
The I2 working group met at 11:00 am on Tuesday, January 13, 2009 with eight members and four guests. John Tengdin and Andre Uribe joined the working group. Mal Swanson chaired the meeting.
Minutes from the last meeting were approved.
C37.234: Oscar discussed the revisions to this document, which included removing definitions that were not related to protection. The working group recommended that Oscar request that all the original terms be kept in the Definitions section of the standard.
C4 Working Group paper: The working group discussed the term, contingency, which will be added to Group #6.
Mal updated the working group on the IEEE Definitions Database:

  1. All working group chairmen can gain free access to the Database by emailing a request for a password to Matt Ceglia at m.j.ceglia@ieee.org.
  2. All working group chairmen need to be sure to have definitions in a separate Definitions section, if they are developing a Standard, Guide or Recommended practice.
  3. Working group Chairmen can feel free to define non-protective terms in this section.
  4. Matt Ceglia will give members of the I2 Terminology working group passwords to the database by next week.
  5. Definitions must have a source document (Standard, Guide or Recommended Practice) to be included in the database. The working group will research with previous members to find sources for some terms in Groups 1 through 3.
Barb Anderson will have the newest revision of Group #6 emailed to working group members and Russ Patterson as DND 6_Rev.059. She will also email revised Groups 1 through 5, as well.
Barb will also check protection terms submitted by I2 to C37.100 to see if they have been included in the Database

Comments and votes to USNC of IEC on TC 95 (Measuring Relays) Standards, projects and drafts.  Reports to PSRC on IEC standards development.

The WG met on January 13, 2009 with 7 members and 1 guest.
Typically, the WG discusses TC 95 documents, some requiring a vote to be sent through USNC.  In this meeting cycle, however, the WG got a break IEC circulated no new standards documents.
Murty Yalla is Convenor of Maintenance Team (MT) 4 of TC 95, developing new IEC relay functional standards. His team met in conjunction with the IEC General Meeting and TC 95 meeting in Sao Paolo, Brazil in November.  He reported on progress of functional standards projects in MT4:

  • 60255-151 Functional standard for over/under current protection excellent draft is nearly ready for final draft international standard (FDIS).

  • 60255-127 - Functional standard for over/under voltage protection  - a single curve implementation similar to -151, making progress and needing more work.

  • 60255-121 Functional standard for distance protection in early phase of development, and needs a lot of work to achieve formal CD.

  • 60255-149 Functional standard for thermal relays not yet begun update 60255-8.

  • 60255-187-1,2, etc. family of standards - Functional standard for differential protection bus, transformer, line, etc. not yet begun, and needs more definition.

Jodi Haasz of IEEE Standards described an accord she developed with IEC after a long deliberation process, on how to achieve dual logo status for C37.94 on optical fiber communications to multiplexers, and C37.118 Synchrophasor standard.  There will be joint development projects in which IEC groups can comment on drafts.  With this, IEC is enthusiastic about participation.

I5: Schematic Representation of Power System Relaying
Chair: Kevin Donahoe
Vice-Chair: Dave Zinn
Output:
Report
Jeff Long filled in for Dave Zinn.

The Working Group met for a single session with 6 members and 6 guests totaling 12 attendees on Wednesday, Jan. 14, 2009.

K. Donahoe started off by noting a drop in attendance due to simultaneous scheduling of WG C16 Relay Scheme Design using Microprocessor Relays.  Both working groups share the same membership, so our WG meeting attendance was split.  This was followed with a review of the minutes from May, introductions and discussion of proprietary and patent information.

Jim Platt of Bonneville Power gave a presentation titled: One Lines & Schematics, The BPA Way.  Information provided on standard representation of multi-function relays (set 1/set 2) in a 500kV breaker-and-a-half scheme.  A full set of one-lines, three-lines, dc control, and wiring drawings were presented.

J. Long provided a sample schematic of how to represent an ANSI 11 multi-function relay in a one-line diagram.

Discussion ensued on ideas for future assignments

J. Long suggested this group should offer methods for depicting IEC61850 GOOSE messages on schematics.  K. Donahoe offered to make a presentation on the use of GOOSE messages to replace breaker failure relays.  He noted that the GOOSE messages were shown in a table format.

In May, WG will need a meeting room accommodating 30 along with a projector.

The WG has completed its task and was disbanded at the Subcommittee meeting.

Output:
Revision of C37.90.1 SWC Tests
The fifth meeting of the Working Group (WG) I20 met on January 14, 2009, in Atlanta, GA, in a single session with 13 Members, and 6 Guests.
The Minutes of Meeting #4 in Vancouver, BC, on September 9, 2008 were approved as submitted.

Review of IEEE PC37.90.1 Draft 3 edits.
Tom Beckwith presented the present status of Draft 3 of the revised standard.  The WG discussed the new revision provided by Mario Ranieri and Jeff Burnworth that edited the Draft 3 document to put it into the latest IEEE standards template format. A MS Word comparison will be performed to assure no changes in content occurred during implementation into the standard format.
The WG then discussed the latest revisions of waveforms and test applications of the associated IEC standards, and how PC37.90.1 should address or harmonize with the revised IEC standards.  Differences in the damped oscillatory were illustrated and discussed.  The WG also discussed the new IEC test requirement to apply a reduced magnitude (2kv) transient waveform in a transverse mode to communication inputs.  The WG questioned if IEC could provide background information or reason for the most recent revisions in waveforms and application.

A vote was taken on whether to adopt the revised IEC damped oscillatory waveform.  The result of the voting was 11 yeas and 1 nay.


Working Group Assignments
Jeff Burnworth: Provide a comparison documents illustrating changes in Draft 3 before/after conversion to the standard IEEE template format.

Mario Ranieri: Identify clauses in Draft 3 that are associated with harmonizing with IEC standards.

Tom Beckwith: Acquire additional IEC standards required for reference.

ITF1: Manufacturer's Services Letter Database
Chair: J. Jodice
Output:
Service Letter Database
ITF#1 met today. There were four PSRC members present.Mark Simon, Simon Richards, David Ward, Mario Ranieri. There have been no submissions of advisories since the last two meetings.

Offers of advisories from Bob Dempsey and Jeff Pond are expectedand will be transferred to the open DB at Doble. Chair will follow-up via email.

Simon Richards will request authorization to allow ITF 1 to provide a link to his companies web advisory & application services, as a means to access these reports.

Many past & present participants are concerned about supplying these public advisories, because of the potential negative impact on their associations with manufacturers.

For this TF to be successful, in providing archival knowledge to PSRC members, it was suggested that a PSRC [officer] request advisories from those relay manufacturers whose products are sold in North America.

I suggest a formal request be issued by the Chair of the main Committee, for maximum impact.

I am happy to provide whatever follow-up to that request is appropriate.
ITF2: Promotion of Dual Logo of C37.2
Chair: John Tengdin
Output:
Service Letter Database
The meeting was attended by five members and guests: Zeeky.Bukhala@ge.com, Jeff Gilbert (jggilbert@pplweb.com), Jodi Haasz (j.haasz@ieee.org), j.t.tengdin@ieee.org, Murty Yalla (myalla@beckwithelectric.com)

The TF Chairman advised that the Chair of the PES Substations Committee has decided to pursue the possibilities of an IEEE/IEC dual logo project with IEC TC 57, and that a letter to the Chairman of IEC TC 57 has been sent but no response to date.

Given the uncertainty of the IEC response, no meeting of I TF2 should be scheduled for the PSRC May meeting.

Output:
Revision of IEEE/ANSI C57.13.3-2005
The Task Force ITF8, Revision of C57.13.3 - Guide for Grounding of Instrument Transformer Secondary Circuits and Cases, met in Georgia 6, Sheraton Atlanta Hotel, Atlanta GA on January 14, 2009.  Four members and three guests were present.

The Task Force discussed the plan to review the relevant IEC standards related to the grounding of instrument transformer secondary circuits and cases.  A list of potential IEC documents was reviewed and approved.  The Chair will work with the IEEE office to obtain copies of these documents.  The Task Force Vice-Chair will create a spreadsheet for the group to use to match up appropriate IEC and other documents to existing sections in the Guide.  Other IEEE documents were suggested for review and will be obtained.  One member (J. Pond) will be reviewing the NEC book.  One member (Z. Bukhala) will be reviewing grounding practices used in China.  The Task Force will need one more session to develop an outline of work, and will submit a proposal to the I Sub-Committee for review.  If the proposal is accepted, a working group will be formed.

The Task Force will meet in Pittsburgh in May 2009 to discuss the spreadsheet of potential revisions to the Guide.  We will use the Wednesday 8:00 a.m. time slot, room for 25 people, and will need a computer projector.
 
Liaison Reports:

RE: Instrument Transformer Sub Committee, Liaison
The Instrument Transformer Sub Committee met in Portugal this fall.  The minutes have been approved but are not yet posted.  The Transformer Committee is not with us at this joint meeting.

  1. The latest version of the C57.13 .2008, Instrument Transformer Standard, has completed Standard Committee balloting and is now out for printing.
    A new task force has been created to review further proposed changes to C57.13.  The chairman, Jim Smith, is seeking any changes that the PSRC members would like to see reviewed.

  2. The optical standard was out for vote so the Working Group did not meet this fall.

Coordination Reports:
None to report .
