WG C3 New Technology for Transmission and Distribution Protection met for a single session on 1/10/2001 with 12 members and 37 guests present.
Two topics were discussed by the working group:
· Anatomy of COMTRADE (Benton Vandiver, OMICRON Electronics)
The discussions were related to the COMTRADE files format and how properties of the configuration file can affect the output, as well as what to look for when analyzing such files.
· Communications Terminology (Alex Apostolov, ALSTOM)
The discussion was related to the terminology related to communication in Local and Wide Area Networks, network configurations and their evolution. The second part of the presentation addressed Object Modeling and it's application to protective multifunctional IEDs.
The working group will meet in Vancouver in a single session. The agenda for the meeting in May 2001 will be provided on the working group web site by April 15.

Output:
Report to Main Committee
The working group met on January 9, 2001 in a single session with 9 members and 11 guests in attendance. Charlie Henville reported about the upcoming related activities planned for the IEEE PES Winter Meeting. Miroslav Begovic informed about some of the opportunities to organize sessions at the conferences in 2001. Damir Novosel informed about the session organized at the IEEE SCI'2000 conference in June 2000, where 6 members of the WG contributed papers. Current draft of the report (version 5.0) was discussed. Most of the material intended to be in the report is included, and at this point, minor additions are necessary, followed by extensive editing work. Appropriate assignments were made to assure that we have a complete final draft by May meeting. There was some discussion about the publication of the report: it could be made available to the general public via a web site from which it could be downloaded without any restrictions, or published as a special publication through IEEE. In either case, the group will prepare a condensed version of the report in the from of a transactions paper. The final decision about publication should be made at the May meeting, and both report and the transactions paper should be completed by September meeting.

Expected Completion Date: December 2001
Output: Guide on the Application of
under-frequency load shedding and restoration
The
working group met on Tuesday, January 9th, with 18 members and 9 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 was reviewed to clarify and confirm commitments for the
remaining writing assignments. The chairman will merge the writing assignments
into an IEEE formatted document, which will be emailed to the working group
members.
Revisions
to existing writing assignments should be made as necessary, with new text in
red, and deleted text in strikeout and emailed to the working group chairman
(Alex). Changes and new writing assignments should be emailed to the working
group chairman by the end of March. These changes and contributions will be
compiled and redistributed by the middle of April, so comments can be received
before the May meeting.
A
few volunteers will be sought to edit the document for consistency.
All
writing assignments shall be submitted in either Word 97 or RTF format with a
file name that includes the document section number, revision number, and
authors last name (<section_number_Rn>_AuthorsLastName>.zip, or .doc,
or .rtf). Figures should be included in the text, and also sent as separate
graphic file attachement. References to Figures included in the text should
include the name of the Figure.
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.

in obtaining outages, and short supply of technically competent
management. Mohamed started his
presentation with the quote “De-regulation has brought hi-tech America the
electricity grid of a third world country”.

C11: Protection Issues during System Restoration
Chair:
T. Sidhu
Vice-Chair:
D. Tziouvaras
Established: 2000
The working group met with 8 members and 15 guests in attendance. Mohamed Ibrahim and Nash Kassam made presentations of their experiences with protection systems during system restoration. A number of protection related issues were identified that will form a part of the report. Mohamed and Nash agreed to provide write-ups identifying and explaining these issues. Demetrios Tziouvaras and Simon Chano who made similar presentations in earlier meetings also agreed to provide write-ups on the protection issues discussed by them. In addition, Brad Nelson and Kalyan Mustaphi agreed to provide write-ups on the subjects of reclosing during restoration and black start respectively. These write-ups are due to the Chairman by end of March 2001. The WG members also agreed to structure the report based on protection issues rather than relay types. The Chairman will circulate a preliminary outline of the report and the above-mentioned write-ups to all WG members for discussions at the May meeting. Kalyan Mustaphi agreed to make a presentation at the May meeting on the topic of protection issues during black starting of units.
TF3 : Deployment and use of Disturbance
Recorders
Task Force TF3 was created to determine PSRC interest in the topic loosely described as “Deployment and use of Disturbance Recorders including IEDs, DFRs, SOE, and DDRs.
There were 31 interested people in attendance at the meeting.
Meeting discussions on possible assignment for a working group included producing:
1. An exhaustive summary paper listing and describing good application papers.
2. A document describing how to find compliance statements of various NERC councils.
3. A descriptive paper discussing deployment and use of recorders
4. Software to automate event analysis
5. An update on recent related topics including microprocessor relays oscillograph recording, smart meters, use of internet for disturbance information, synchrophasors, UCA, GPS, Etc.
There was also lengthy discussion on developing a document containing reasons, arguments to help justify more disturbance recorder installations.
Finally, the following assignment is proposed for a new working group “Develop a report to the main committee on the Deployment and use of Disturbance Recorders for Protection”. The report will initially cover:
· Types of monitoring equipment
· Placement of equipment
· Frequency sampling rates
· Examples of effective use
· Reference to papers
A detailed outline will be developed if the proposed working group is approved.
Phil Winston
Phase III compliance is underway. Protection related standrads involve: Disturbance monitoring, Gnerator tripping, and Undervoltage load shedding schemes. Compliance seminars are scheduled and the schedule for compliance fillings have been communicated to all regions.

Liaison Report of the IEEE Working Group on Power System Dynamic Measurements Meeting at the IEEE/PES Summer Power Meeting in Seattle, WA on July 17, 2000
By invitation, a presentation was given by Mr.Alex Bykhovsky. He is developing software to look at the disturbances and analyze the events. A copy of the presentation was distributed to the group and some plots were shown on the computer.
By invitation, a presentation was given by Dr.John Hauer of the PNNL on the WSCC Measurement Compliance of the NERC requirements. A draft prepared by the WSCC was also distributed by Mr.John Hauer to the Working Group.
After discussion of the title, the WG decided to write a paper “Preferred Capabilities for Power System Dynamics Measurements”. The chair was tasked to find a title that would avoid having to meet standards requirements. The chair was tasked to contact vendors to seek individuals for the Task Force. He asked the Working Group to suggest vendor names and information. Several technical issues were discussed as appropriate for the WG paper, including measurements necessary to determine: How close to the edge; response of the system loads; Initiating events; Data rates; Quantities; Sources of data; Uses of measurements [goals of measurements]; Others. Martin, Bhargava, and Schulz agreed to put together an outline and send it out to the Task Force.
