WG Reports:

C1: Cyber Security Issues for Relaying

The C1 working group met in 2 joint sessions with the Substation Working Group C1. There were 5 members and 20 guests present in the first session and 7 members and 16 guests present in the second session.

Sam Sciacca (chair of PSSC C1) gave a status update of the Substation Working Group.

Focus of C1 group is security of data and information in substations. Focus is on security of information from authorized individuals (or one who recently had authorized access) in substation and remote. Not addressing hacking, other groups are looking at that. Looking at procedures and audit trails.

Joe Gould of RuggedCom Inc gave a presentation on networks and network security issues. Specific items discussed include: Routers, Ethernet Switches, Firewalls, VPN, RAS (remote access service), Security policy.

Rick Liposchack of Microsol gave an overview of the INEEL Security Testbed Program.

There was discussion of the future direction of the two working groups. There is sufficient overlap in the issues being addressed by both working groups that the feeling was a joint effort is in order. In order to provide a timely output, a report should be produced with a recommended practice or standard developed at a later date if desired.

Solveig Ward and Sam Sciacca are to work together and decide on an outline for the report and hand out writing assignments.

C2: Power Quality Issues in Protective Devices

C2 met Tuesday September 14, 2004 in Portland, OR with 5 members and 3 guests present. The total number of members is 26.

Final draft of the report was sent out for working group ballot in August. No comments were received and only positive votes.

A contribution from Imacculada Zamora was received on the “Influence of Harmonic Distortion on Digital Protective Relays”. This section will be included in the report and redistributed to the Working Group for comments by mid-October.

Next step is to send the final draft to the C-Subcommittee for balloting by mid-November with comments/ballots returned by December 15th. All comments will be reviewed at the January 11-14th PSRC meeting in San Diego.

Again - all members have been asked to review the document. The latest version of the document will be posted on the IEEE PSRC C Subcommittee website under WG C2. The link to the PSRC site will be provided in the distribution of the minutes along with the document.

C3: Processes, Issues, Trends and Quality Control of Relay Settings

Working Group C3 met Tuesday, September 14, 2004 in Portland, OR in a single session with 10 (of 26) members and 11 guests participating. 2 of these guests requested to become new members increasing the total membership to 28.

Outline was reviewed and final approval was obtained from the group. No additional changes to the outline are expected.

Most section owners have provided material for their respective sections. The initial draft will be sent to Damir Novosel, for posting to the PSRC website by September 24. Chairman to send link along with minutes to working group members.

Section still requiring input:

· Section 3.0 Quality Control and Quality Management System (Eric Udren, owner)

· Section 4.4 Test values (Mike Jensen, Gary Kobet)

· Section 6.3 Relay maintenance records (Mike Jensen)

· Section 8.0 Access Control (Solveig Ward, owner)

These individuals committed to complete these assignments by October 8. The document will be updated and reposted to the PSRC website. An e-mail will then be sent to all members and guests, directing a review of the updated draft to provide comments by December 15.

Part of the review should include a specific review of each section to develop recommendations based on our industry expertise. The intent is to provide this guidance to the regulatory bodies as the domain expert recommendations.

Dave Angell provided an overview of the WSCC requirements for relay setting review and analysis of relay operations/misoperations. Arif Cubukcu mentioned that one Canadian utility has similar guidelines and will provide their documentation. This material to be referenced in the document.

To review, output of the working group will be a PSRC report, with an associated Transactions paper summarizing the report. Target date for completion is 2006.

The January meeting will be used to review comments received on the October draft.

C4: Industry Experiences With Power System Protection Schemes (PSPS)

WG C-4 met in double sessions with 11 members and 30 guests.

Review of Assignments

Topics reviewed included:

· Definition for the scope of survey drafted by Charlie Henville – The scope to include UF, UV, SPS, and RAS applications. Also, noted was the possibility of NERC definition of SPS may be changing. If or when NERC revises the definition, the WG will review the new definition and if in-line with the C-4, the WG will use NERC acronym

· Outline has been proposed by Mark Adamiak, based on the preliminary list of questions discussed by the WG members. The outline will be mailed to the attendees for comments

· TW Cease will help the WG and coordinate with CIGRE to get a broader audience – There is a joint session of CIGRE and PSRC in September 2005 and information will be communicated with CIGRE in advance

Other discussions included:

· Industry experiences with wide area, RAS, and such applications should be highlighted

· Include operating practices as part of the survey

· Capture functionality of how PSPSs are to operate and work

· Survey questions should be such to add value to the users and may have some benefit to the manufacturers of the protective relays

Suggestions were made to include contact persons in case respondents have questions

Also, three members volunteered to prepare a process for ways most efficient for survey to be successful in terms of receiving responses and useful information for preparation of report

Presentation by Miroslav Begovic

The second session started with a review of the IEEE / CIGRE Committee report Industry experience with special protection schemes Paul Anderson and LeReverend

After the presentation, members discussed the next steps and members with new assignments. Writing assignments received will be distributed electronically to the members for the January 2005 meeting

C5: Deployment and use of Disturbance Recorders

The Working Group met on Wednesday, September 15, 2004 with 8 members and 5 guests present.

Vice Chairman Tony Napikoski conducted the meeting for chairman Strang who was unable to attend.

A copy of Draft 8 of the report was distributed. Outstanding writing assignments were reviewed. Several were received. The report needs to be edited with some rearrangement to better follow the outline.

Jim Ingleson did a presentation on the website where an earlier draft of the paper exists as links to individual sections. It was agreed to modify the website during the editing phase to keep the document as one piece.

A planned presentation by Larry Smith was postponed due to Larry’s absence.

C6: Relay Engineering in Power Engineering Curricula

C9: Under Frequency Load Shedding and Restoration

The working group met on Tuesday, September 14th, with 10 members and 13 guests present. Draft 4 of the document has been updated based on comments received from the working group members. The draft document will now be sent to the IEEE Editor for pre-ballot review. The balloting body will be formed, in anticipation of balloting later this year. Because the balloting process is expected to go beyond year end, we are applying for a PAR extension.

The working group discussed writing an overview paper or transaction paper to provide a deliverable for presentation at a technical conference. The majority of the attendees agreed that a transaction paper, and an accompanying summary paper should be written. Three working group members (Alex Apostolov, Ken Birt, and Pratap Mysore) volunteered to write the transaction paper.
