The working group met on Wednesday, January 12th, with 21 members and 23 guests present. The PAR has been submitted and the working group document has been assigned the number PC37.117. The working group reviewed the guide’s scope, purpose, and outline that were developed at previous meetings. Attention then focused on developing writing assignments for items in the outline. The outline, and writing assignments received to date, will be emailed to members for their review. 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 mid April to allow time for these contributions to be reviewed before the next PSRC 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.

Change of Vice-Chair:
Mr. Rich Hunt will replace Mr. T. Sezi as Vice-Chair of the WG.
Next meeting: For our next meeting, we need a room for 40 participants and a projection system to run a powerpoint presentation.
The Task Force met on January 12, 2000, with 29 participants in attendance. Thirteen of them indicated that they are willing to become members and contribute to the work. It was clear from the discussions that there is sufficient interest to form a WG.
The following title and assignment for the WG were agreed to:
Title: Protection Issues during System Restoration
Assignment: To study relaying issues during system restoration following a major disturbance and suggest remedial measures.
It was also agreed that the initial output of the WG will be
a PSRC report which will be later summarized in the form of a transaction
paper. Demetrious Tziouvaras
volunteered to be the vice-chairman of the WG.
If the formation of the WG is approved, two presentations will be made
at the first meeting of the WG.
The Phase 2 Compliance Testing program is getting kicked off. 5-8 Protection & Control
Standards 7 measures are in Phase 2. Nothing else of significance to report.
It is proposed to address following:
- Impact if present practices on power quality
- Power quality monitoring functions in the relays
-
Standards related to power quality.
Initiate Task Force to define the assignments.
