Working Group reports:
C2: Power Quality Issues in Protective
Relaying
Chair: T.W. Cease
Vice Chair: S. Kunsman
C2 met Wednesday January 15, 2003 in Phoenix, AZ with 7 members and 12 guest present. The total number of members is 26.
TW Cease reviewed the completed writing assignments and reviews. Since David Hart is no longer participating, his open writing assignment (section 3.6.1) is now assigned to Steve Kunsman.
Patrick Carroll commented that Section 3.6.3 is written based on transmission where ITI curve is traditionally applied at the distribution level. Additions for the distribution network are needed. Patrick will contribute to this section.
Summary section will be completed by TW Cease and Steve Kunsman once the paper is complete. All members should be working on the bibliography section. Anyone who has references that need to be noted should forward these to TW Cease.
Section 3.4 and 3.5 need input from IEC and EN domain expert on how these standards are applied to relaying. Steve Kunsman will locate source from Europe to contribute to these sections.
Action Items:
1. Assignments Reviews assignments due February 28, 2003
Section 6 – Roger Hedding
All sections – all members
2. Additional writing assignments due February 28, 2003
Section 3.6.3 Application of ITI Curve for Distribution Networks Patrick Carrol
Section 3.6.1 Writing assignment on issues of PQ monitoring and relays Steve K.

writing assignments due no later than February 28, 2003
Section 3.4 and 3.5 Steve Kunsman will
recommend a person
All authors to review section and to reduce figure size (e.g. jpg format)

C5: Deployment and Use of Disturbance
Recorders
Chair: B. Jackson
Vice Chair: W.M. Strang
Working group met on Tuesday at 4:30 p.m. with 7 members and 17 guests.
The chairman reviewed the assignment of the WG and a purpose statement to clarify what should be included in the paper.
The group started a review of definitions and terms, which led to much discussion. Other items discussed include the outline of the paper and how various topics should be arranged in the outline. It was suggested to make four main topics and revise the outline to include four main topics as follows:
Introduction
Applications/ analysis
Deployment
Definitions
Assignments were made on two topics. The chairman will work with those assigned to develop a more detailed outline to be available to the group before the next meeting.
Next meeting requires 1 session room for 30 people & computer projector.
C8: Phasor-Based
Models for Analyzing Relay Performance
Chair:
M. Meisinger
Vice Chair: M. S. Sachdev
The Working Group met at 11:00 AM on January 14, 2003 in Raven Room, Phoenix-Scottsdale-Paradise Valley Embassy Suites, Phoenix, AZ. Eight members and thirteen guests were present.
Mohindar Sachdev reported that he had edited the draft but a few modifications and corrections are needed before the paper is ready for publication. He further reported that contribution for Section II - Definitions of Terms was received on January 12 and will be incorporated in the paper. Published equations were provided by Gabriel Benmoyal and Elmo Price some time back but have not been incorporated into the paper. The equations will be incorporated in an Appendix of the paper.
Juergen Holbach agreed to revise the sections on Ground Fault Distance Relay and parallel line compensation so that the number of equations in those sections is minimal. Mohindar Sachdev will add an abstract, key words and a conclusion.
It is planned to complete and circulate the paper among the members of the WG and C Subcommittee for comments of Substance before the next meeting of the PSRC.
At the conclusion of this business the meeting was adjourned.
Next meeting requires 1 session & room for 25 people.
C9: Underfrequency Load Shedding and Restoration
Chair: A. Apostolov
Vice Chair: K. Behrendt
The working group met on Tuesday, January 14th, with 16 members and 16 guests present. The working group discussed a proposed schedule to expedite the completion of the guide. Draft 1 of the document was circulated for comments prior to this meeting. Any additional comments received by the end of January will be incorporated into Draft2, which will be sent to the working group by February 15th. Draft 2 will be accompanied by an approval survey. Survey results should be sent to the working group chairman be March 31st. Survey results, and associated comments should be resolved by April 30th, at which time a final working group document should be ready for balloting.
The working group confirmed their assignments to review individual document sections, and read the entire document to assure conformity and check for duplication of material. Guests who attended the meeting were also invited to review the document.

Reference:
Title: PC37.117 - Guide for the Application of Protective Relays used for Abnormal Frequency Load Shedding and Restoration
Scope:
This project will develop a Guide for the application of protective relays used for load shedding and restoration during electric power system abnormal frequency conditions. It will present background information, bibliography, and recommendations. It discusses abnormal frequency power system behavior, existing load shedding and restoration practices, the abnormal frequency function of typical protective relays, and possible new methods for improved load shedding and restoration. This project is limited to electric power system applications and will not include Abnormal Frequency Protection for Power Generating Plants.
Purpose:
There is currently no IEEE Guide for the application of protective relays used for load shedding and restoration during electric power system abnormal frequency conditions. This Guide will complement the IEEE Guide for Abnormal Frequency Protection of Power Generating Plants. It will provide information to assist in the application of load shedding and restoration schemes. Methods and examples will be provided.
Milestones:
The PAR has been approved and the working group document has been assigned the number PC37.117.
Next meeting requires 1 session room for 40 people & computer projector.

settings, multiple setting groups, documentation handling, database
consistency, relay records, etc.
Task force chairman: Steve Kunsman
Next meeting requires 1 session, room for 30
people + computer projector
CTF7:
Multi-station and System Testing
To address
End-to-end testing using secondary signals, Special Protection Schemes, etc.
