C3: Trends and Issues with Relay Settings
Chair: Steve Kunsman
Vice Chair:
Gary Kobet
Working Group C3 met Tuesday, January 13, 2004 in Tampa, FL in a double session with 12 (of 18) members and 26 guests participating. Three of these guests requested to become new members increasing the total membership to 21.
The first session was dedicated to utility presentations on the relay setting process.
· Randy Horton (presenter) & Rick Cornelison – Alabama Power Company
· Jim O’Brien – Duke Energy
· Russ Patterson - TVA
Some of the main issues and concerns raised during the open discussion were:
· Duplicate Settings database and how to assure control
· Revision control of paper/e-copy of settings
· Most utilities are migrating to electronic masters but Canadian regulators require a approved hard copy of the setting/designs.
· In a device failure situation, how to assure the database settings are compatible with the firmware of the replacement device.
· Some tools do not support an audit/history trail of changes.
· Security and access outside the protection department.
The 2nd session was kicked off with a review of the C3 objectives and work statement. A discrepancy on the working group title was discussed (Protection Systems vs Relay Settings). It was decided that the scope shall be limited to Relay Settings Process.
Reviewed the initial outline.
· Similarities between Relay Vendor product development processes and the utility relay setting processes were discussed. From the creation, implementation and execution these process have synergies. Relay vendors typically have a Quality System that defines the process and can be certified to ISO-9001. This discussion resulted in the addition of a new outline section Quality control and quality management system.
· Relay settings are typically “set and forget” and will be in place until a misoperation occurs. The group discussed the need for peer reviews of the initial settings to be included in the relay setting process as well as a periodic review of settings installed base.
Relay
calculation development is performed with a certain set of contingencies
(typically n-1). With the events like
the NE blackout, it was raised is the n-1 rule of thumb sufficient. This should be taken into consideration
section on Relay Setting Process.
C4: Wide Area Protection and Emergency Control
Chair: M. Begovic
Vice Chair: D. Novosel
The working group did not meet in January.
Papers are complete. After some final editing the paper will be circulated to the wg.
Once the papers are circulated and approved by the officers, they will be submitted to transactions. This will complete the assignment of this working group.
C5: Deployment and Use of Disturbance
Recorders
Chair: B. Jackson
Vice Chair: W.M. Strang
Working group meeting was held on Tuesday Jan. 13 from
4:30-5:45 pm with 10
members and 16 guests.
The chairman reviewed the purpose of the paper and status
of the draft
document. The draft
is listed in HTLM format on the PSRC, C-5 working
group site.
Four writing assignments were received and reviewed during
the meeting. A
number of other assignments are still outstanding and the
chairman has
contacted those members.
New assignments were made and group was asked to
review the whole document as several section overlap.
About 80% of the outline has been completed or assigned. The chairman will
work with members to complete the remaining sections.
Jim Ingleson provided a brief review of the NE blackout and
disturbance
monitoring. Data on
bus frequency and voltage was very good.
Time tagging
of breaker trips was not very good.

reviewed the contributions and exchanged ideas.
c)
Discussions on the
Title of the WG
For clarification
purposes, the participants discussed the Title of the WG and the scope outlined
by the C Subcommittee and suggested a revised Title, and agreed with the
development of a guide for system testing.
The title will be revised from Multi-Station and System Testing, to
Power System Protection Testing. Below
is a summary discussion
Scope:
The Working Group will develop a guide for Power System Protection Testing. The Guide will include System Application Test Requirements, Scope and level of tests and Benefits of system testing for Overall Protective Schemes. This assignment encompasses overall system testing procedures (generators, line, transformer, capacitors, SPSs, end-to-end testing, distributed application within substation, etc.), data collection requirements, as well as the test procedure definitions. The WG will describe the methods, extent, and types of system tests for protection at various voltage levels and applications.
Working Group Member Discussions and Agreements:
The WG members have discussed the format and the final product in previous meetings.
The alternatives discussed included:
After
discussions in different sessions, the WG members agreed that the C-7 WG will
aim at preparing a Guide for the overall benefits and types of tests
recommended for the overall system tests.
A transaction paper may later be prepared as a result of the C-7
efforts.
C8: Phasor-Based
Models for Analyzing Relay Performance
Chair:
M. Meisinger
Vice Chair: M. S. Sachdev
The Working Group met at 09:30 AM on January 14, 2004 in Grand Ballroom East, Wyndham Westshore Hotel in Tampa, FL. Six members and six guests were present.
The Chairman reported that Draft 9 of the WG paper was balloted in the Working Group. Seventeen (out of a total of 22) voted for approval and approval with comments. No negative ballots were received.
The chairman further reported that the suggested changes, which are editorial in nature, will be incorporated in the draft and it will be submitted to the Subcommittee members for comments of substance. If no comments of substance are received within four weeks of the submission of the paper, it will be submitted to the officers of the PSRC for approval and permission to publish in the IEEE Transactions on Power Delivery.
At the conclusion of this business, the meeting was adjourned.
C9: Underfrequency Load Shedding and Restoration
Chair: A. Apostolov
Vice Chair: K. Behrendt
The working group met on Wednesday, January 14th, with 21 members and 10 guests present. Draft 3 of the document had been circulated, with an informal working group survey to soliciting comments. Only 6 ballots have been returned, so the deadline for returning ballots was extended to Monday, January 19th. Comments from the ballots will be summarized and turned over to a review committee consisting of Rich Hunt, Ron Beazer, Ken Birt, and Rich Young. The review committee will perform an editorial review, harmonize the document style and content, eliminate repetition, and incorporate additional figures, as necessary.
The review committee should provide a finished document by March 15th, at which time the document will be sent to the working group with a second informal ballot. Any negative working group ballots and significant comments will be resolved during the May, 2004, meeting.
The final document will be completed by July 15th, at which time we will start the official balloting process to gain approval for the guide.
The working group discussed underfrequency load shedding issues that may have been raised by the August 14th, 2003, Northeast blackout. General consensus was that the UF schemes worked as expected, but the network collapse was beyond anything that could have been prevented by UF load shedding. There was some discussion about the use of undervoltage supervision, and how this should be set.

approved with comments. Most of the
comments were of editorial nature and were resolved during this meeting. The paper is now ready for review by the
subcommittee members.
Related Activities:
A Wide Area Measurement System (WAMS) is being developed in the Eastern USA. The Eastern Interconnection Phasor Project is being coordinated and facilitated by the U.S. Department of Energy (DOE) through the Consortium for Electric Reliability Technology Solutions (CERTS). Reliability councils and standards organizations are enabling this work. System operators, transmission owners and manufacturers are implementing the system.
The Eastern Interconnection Phasor plan embodies a vision for the overall project in two stages. In the near term, the project team seeks to use expertise and equipment developed under auspices of the U.S. Department of Energy to deliver value to project participants in the Eastern Interconnection. Most of this existing expertise involves off-line analysis and is supportive of planning activities. In the long term, the vision calls for delivering value within the operations environment using new inter-regional information and measurement systems.

CTF1 Cybersecurity Issues for Relaying
Task Force Chair:
S. Ward
The CTF1 task force met with 29 people, of which 12 (plus 2 after the meeting) indicated that they would become members. A task force was suggested at the September meeting based on a recent Cyber Security standard issued by NERC. The “Cyber Security Standard” and another relevant document; “Securing Remote Access to Electronic Control and Protection Systems”, were presented during the meeting (these documents can be found on http://www.nerc.com/~filez/standards-cyber.html and http://www.nerc.com/~filez/cipfiles.html).
The present NERC Cyber Security Standard specifically excludes relaying and the group recommended that a working group in PSRC should be formed. The C subcommittee approved the recommendation and the new WG ‘C1 Cyber Security Issues for Relaying’ will start regular sessions at the May meeting.
The group will meet at the May 2004 meeting, single session. A room for 30 people with a computer projector is requested,
- To prepare a report documenting the status of cyber security standards, recommended procedures and guidelines for cyber security for protective relays
- To provide a liaison to other agencies preparing cyber standards in fields related to relaying
- To provide timely review from a relaying perspective of draft documents prepared by other agencies
One year was suggested (May 2005) but perhaps this is not realistic. To be further discussed at next meeting.
Working group C1 Cybersecurity Issues for
Relaying has been appointed to complete
this assignment. Chair will be Solveig
Ward. Vice-chair will be Jim O’Brien.
CTF4 Special Protection Schemes
Task Force Chair:
M. Begovic
The TF met in a single session with 22 guests in attendance. It was moderated by Miroslav Begovic. The meeting started with the brief presentation on the earlier (1993) effort on the same topic, conducted under the auspices of IEEE PES and CIGRE under the leadership of P. Anderson and B. LeReverend. The IEEE Transactions paper, which was the end product of their survey, was published in 1996 and served as a source of information for the presentation.
The discussion that followed was centered on the assignment, deliverables, timeline and leadership of the Working Group under consideration. The overwhelming majority of the attendees were in favor of forming the new Working Group, with 12 attendees expressing interest in being the founding members. Some discussion ensued on what should be the scope of the new WG (special protection schemes, system protection schemes and remedial action schemes were discussed in that context). Also, various aspects of the possible focal issues were discussed (RAS design, operational experience, reliability, redundancy). It was decided that a possibility of another joint effort with CIGRE, and possibly other Committees within the IEEE PES. The new survey should be created on the internet, which should greatly facilitate the response. Jaime deLaRee will investigate the availability of the survey processing software which was once used within the PSRC for similar purposes. The meeting adjourned at 9:15.
Proposed Assignment:
It is proposed to conduct a comprehensive survey of the utilities world-wide with the objective of accumulating updated industry experience with the remedial actions protection and emergency control schemes, from a variety of perspectives including, but not limited to design, operational experience, reliability, etc. The work should be conducted in the realm of an internet-based questionnaire. The responses should be sought through all media of communication available and with the assistance of all other interested partners (IEEE PES, CIGRE, etc.)
Deliverable:
The results should be compiled in the form of the report to the Main Committee of PSRC, as well as the Transaction paper.
Timeline:
Expected completion date should be no later than May 2006 (3 years).
Leadership:
It would be desirable to have someone with utility affiliation in the leadership position for the new Working Group. Corporate memory and experience could be provided by some of the former members of the WG on wide area protection and emergency control (C6), who could assume the position of the Vice-Chair.
The subcommittee accepted the proposed assignment. A new working group C4 will be formed with the following title: Industry Experience with Remedial Action Schemes
