The System Protection Subcommittee did not meet in
Madison. Four of the working groups did meet.
WG
Reports:
C2: Power Quality Issues in Protective
Relaying
Chair: T.W. Cease
Vice Chair: David Hart
Established:
2000
Expected Completion Date: 2003
Output:
Report to Main Committee and IEEE Transactions Paper
Charlie Henville presented a paper on Protective Relays and power quality based on a paper given at the summer power meeting
C5: Deployment and use of Disturbance
Recorders
Vice Chair: W.M. Strang
Established:
1994
Expected Completion Date: Continuing
Output:
Report to Main Committee and IEEE Transactions Paper
The working group met in Madison Wisconsin with 7 members and 10 guests. Chairman Barry Jackson was unable to attend due to recent events, the meeting was chaired by vice chairman Bill Strang.
The purpose of the paper was reviewed and discussed. It was indicated that one of the objectives of the working group should be to produce this document in a timely manner as the subject is considered by the attendees as necessary for their efforts in the near future. Without the aid of a printed agenda, the group outlined their interests and needs as shown in draft 3 of the outline. Specifically, areas of interest for discussion in the paper that were not previously included are:
Definition of waveform data collected by various devices
Discussion of analysis within the monitoring device of the data collected
Other uses of collected data, such as a diagnostic tool for targeting
equipment maintenance
Data formats – reference to COMTRADE standard
Data retrieval – file naming convention paper (H8)
Status of related working group efforts, such as Improved Analysis of
Substation Data (I19)
It was suggested that the paper include a summary table indicating the
advantages or applicability of outputs of the various available monitoring
devices.
Following a discussion of short and directed questionnaires, the group
concluded that this was an expeditious way of collecting information on the
types and characteristics of available monitors from the manufactures and the
application needs of the utility industry. Bill Strang will submit these to the
chairman before the next meeting.
C8: Phasor-Based
Models for Analyzing Relay Performance
Chair:
Mike Meisinger
Vice Chair: M. S. Sachdev
Established, 1997
Expected Completion Date: 2002
Output:
Transactions Paper
The
Working Group met with 3 members and 1 guest. Juergen Holbach's contribution
was distributed and discussed. The lack of new material from members and guests
with assignments continues to impede progress in completing the assignment. The
rewrite of portions of Section III is specifically critical in bringing the
content of the paper into alignment. Irwin Hasenwinkle offered comments to the
overall flow of the paper and will provide these comments in an e-mail for
distribution to Working Group members by the Vice-Chair.
After
the Chair and the Vice-Chair have determined which assignments are still
outstanding, the Chair will contact those contributors with outstanding
assignments to determine if their input is forthcoming or re-assignment is
required. The plan is to have all contributions compiled and distributed 2
months prior to the January meeting.
C9: Underfrequency Load Shedding and Restoration
Vice-Chair: K. Behrendt
Established, 1999
Expected Completion Date: December 2001
Output: Guide on the Application of
under-frequency load shedding and restoration
The working group met on Tuesday, September 18th, with 6 members and 10 guests present. The working group reviewed the guide’s outline and review commitments for writing assignments. A few writing assignments were received, but several are still needed. The chairman discussed a new schedule get a draft document created. All outstanding writing assignments should be submitted by the end of November, so the first complete draft document can be assembled and circulated for comments by the end of the year. A comment spreadsheet will be sent out to working group members with the draft to permit comments on the draft in a standard format. Contributors are requested to select a section of the document to review, preferably a section that they did not write.
Al Darlington joined the working group, and will create or edit drawings for the guide. Al will also contribute documentation based on load shedding schemes used in Florida.
The guide will include web addresses for links to other sources of under frequency load shedding documentation.
The scheduled completion date of December 2001 will not be meet. Perhaps December 2002 may be a more achievable completion date.
The working group expects to meet in single session at the next PSRC meeting, and needs a room for 40 with a projector screen and outlet strip.

Report of the IEEE PES Power System Stability Controls SC to the PSRC
Gary Michael
The IEEE PES Power System Stability Controls Subcommittee (SC) had a business meeting on 17 July 2001 in Vancouver, with around 60 members and guests attending. Following the business meeting, the SC sponsored a morning technical paper session with two transaction’s papers and three proceeding’s papers. In the afternoon, the SC sponsored the panel session Recent Experience with Emergency Stability Controls. The panel session attendance was 60plus.
The Power System Dynamic Measurements WG chaired by Dick Schulz held a meeting on 16 July. The WG is preparing the paper "Preferred Capabilities for Power System Dynamics Measurements."
The SC formed a Task Force on Fast-Acting Load Control for System and Price Stability, with a kickoff meeting on 16 July. Jeff Dagle is chairman. Recalling the 2001 WM panel session, the SC are planning a second panel session at the 2002 WM. A position paper is also planned. The idea is to take advantage of current need for direct load control/real-time pricing for demand management and price-based load reduction. With appropriate design, the same infrastructure can be used for stability control, especially longer-term voltage stability.
The SC Task Force on Test Systems for Stability Controls chaired by Ian Hiskens did not meet.
The SC plans a 2002 WM panel session on emergency voltage stability controls. A 2002 SM panel session on stability controls involving power electronic devices is under consideration. Also under discussion is work on advanced generator controls for restoration and islanding.
