Output: Transactions Paper
The Working Group met at 9:30 AM on September 20, 2000 in Seminar room, Rolling Green Ramada Inn, Andover MA. Seven members and eleven guests were present.
Drafts of two sections reassigned at the May meeting had not been received. The WG reviewed the outstanding tasks and assigned the Chair to follow up the completion of the drafts with Jaime De La Ree, Mika Begovic, Irwin Hasenwinkle and Mike Meisinger for obtaining the drafts from them.
After some discussion it was decided that the introduction should include an appropriate definition of the scope of applications in which relay engineers can use phasor models. Gabriel Benmouyal agreed to provide a draft of this addition. He also agreed to provide and example of CVT for including in the paper.

C9: Underfrequency Load Shedding and
Restoration
Chair: A.
Apostolov
Vice-Chair:
K. Behrendt
Established,
1999
Expected
Completion Date: 2001
Output:
Guide on the Application of under-frequency load shedding and restoration
The working group met on Tuesday, September19th, with 22 members and 7 guests present. The working group reviewed the guide’s scope, purpose, and outline that were developed at previous meetings. Some writing assignments have been received. The outline, and writing assignments received were emailed to members for their information and review. The outline was reviewed further to identify any missing elements and clarify existing elements. Additional writing assignments were made. This information will also be posted on the working group website when that is available in the near future. New writing contributions will also be added to the web site as they are received. Writing contributions should be submitted by the end of November so that a draft document can be prepared and sent out for comments before the January meeting.
The scheduled completion date remains December, 2001. The working group expects to meet in single session at the next PSRC meeting, and needs a room for 40 with a projector screen.

Nothing of significance to report.
Liaison Report of the IEEE PES Power System Stability
Controls Subcommittee (SC) to the PSRC Gary Michael
The SC met at the 2000 SPM on 19 July 2000 in Seattle with around 60 people attending. The meeting included special presentations by Vijay Vittal on robust PSS and by Paulo Gomes on the March 11, 1999 Brazilian blackout. The Brazilian blackout is described in two CIGRE papers of the 2000 Paris meeting.
The SC also sponsored a technical paper session with two transaction papers and three proceeding papers, and co-sponsored the panel session on Power Plant Secondary (High Side) Voltage Control. Both sessions were well attended. The panel session is documented on pages 271 - 312 of the proceedings.
At the Columbus, Ohio 2001 winter meeting, the SC is planning a special technical session (panel session with tutorial content) on generator field circuit time-overload capability. The session is co-sponsored by the Excitation Systems Subcommittee, and is expected to be on Monday afternoon, January 29.
The SC is initiating work on direct load control for price and voltage stability. Jeff Dagle from Pacific Northwest National Laboratory will lead the work with cooperation from the Power System Operations Committee. A panel session is planned for the Columbus meeting (Tuesday afternoon, January 30). A position paper may follow.
The SC is starting to plan a panel session on recent experience with special protection systems for the 2001 summer meeting. This will include implementations following major disturbances, and use of PLC and other digital controls.
