C: SYSTEM PROTECTION SUBCOMMITTEE

Chair: D. Novosel

Vice Chair: T. Seegers

 

The system protection Subcommittee met on September 11 with 33 people attending including 18 members.  Steven Kunsman, Rich Hunt, Pete Solanics, and Ken Behrendt were welcome as new members of the subcommittee.

 

Chairman Novosel reminded working group chairman of the importance of reviewing their membership lists and retaining only those members who are contributing to the assignment of the group.

 

It was noted that several working groups will complete their assignments by the end of next year.  Proposals for new working group assignments are being solicited from anyone who has ideas.

 

Working Group reports:

C2:    Power Quality Issues in Protective Relaying

Chair: T.W. Cease

Vice Chair: S. Kunsman

C2 met Wednesday Sept 11, 2002 in Ponte Vedra FL with 7 members and 18 guests present.  The total number of members is 27.

 

TW Cease reported that no writing assignments were submitted as committed last meeting.  This is a major problem to complete the report.  It was recommended that the Chair and Vice Chair take a more aggressive role in reminding the members of their assignments/commitments.

 

Damir Novosel (Chairman of C subcommittee) said the working group should strengthen their participation and commitment to the goal of the group.  If members cannot commit then they should be removed from the committee.

 

Bob Beckwith had concerns that there were no standard for the definition of long-term measure of the voltage deviation.  IEEE 1159 was referenced as a source for these definitions.

 

Charlie Henville concerned about protection based on power quality events.  For example, high magnitude of harmonics causes problems in capacitor bank application.  It was suggested that a section could be added on protection (tripping versus alarming).  Harmonics impact on protection relays (IEEE standard 519 addresses some of these concerns) could be summarized as a new section.

 

Charlie Henville concerns on high order harmonics (greater than 1) and geometric magnetic influences (Bill Feero has done work in this area) on generator protection.  Some concerns over the negative sequence protection as to whether tripping was a good or bad event.

1. IEEE PES Power System Stability Controls SC            Gary Michel

 

On July 23, the Power System Stability Controls Subcommittee met from 8:00 to 9:00, with 65 members and guests attending. At the Subcommittee meeting, John Hauer presented an update on WECC wide-area measurements.

 

Following the business meeting, Willie Wong chaired a technical paper session with four transactions papers and one proceedings papers. On July 23 afternoon, Power System Stability Controls Subcommittee sponsored the panel session Power System Stability Controls Using Power Electronic Devices; the attendance was 70 - 80. The WG on Power System Dynamic Measurements, chaired by Dick Schulz met on July 22, minutes below. The TF on Fast-Acting Direct Load Control for System and Price Stability chaired by Jeff Dagle met on July 22 (Steve Widergren chairing). The TF on Benchmark Systems for Damping Controls chaired by Ian Hiskens met on July 24. Juan Sanchez-Gasca provided a report of the Excitation Subcommittee TF on Power System Stabilizers.

 

Plans for the Toronto meeting in July 2003 include panel sessions on:

-    Modeling and Controls for Wind Generation/Power System Interaction

-    Direct Load Controls for System and Price Stability (sponsored by Task Force)

 

ADMINISTRATIVE ITEM: New Subcommittee chairman
Following the Toronto meeting, Nelson Martins will be Subcommittee chairman and Juan Sanchez-Gasca will be Subcommittee secretary. The Power System Dynamic Performance Committee policy will be four year terms for subcommittee chair and secretary, with the secretary becoming the new chair. Congratulations to Nelson and Juan.

 

The Working Group on Power System Dynamics Measurements (WG) met on Monday, Jan. 28, with 25 present. Dick Schulz, chair, opened the Meeting. Harold Kirkham spoke to the activities of the Instrumentation & Measurements committee.

Several members of this WG noted that Power System Relaying Committee (PSRC) activities have overlap with the work of this WG. These include: (1) The PSRC WG C5 is preparing a report "Deployment and Use of Disturbance Recorders"; it should be reviewed and referenced in section 1.2 of our report, (2) PSRC WG H8 [chaired by Jim Ingleson of this WG] is developing a standard naming format for disturbance recordings, (3) Ken Martin [BPA, member of this WG] chairs the PSRC WG H11 that is revising a standard (IEEE std 1344 and rewrite version C37-118) provide the synchro-phasor format. It was said that these PSRC reports should be available on the web site pes-psrc.org; the chair noted that he has not found any of this on the web yet, but has been able to get them by informal contacts with the PSRC WG chairs.  Dick follows these activities, and attended some of these WG meetings.  Jim Ingleson volunteered to create and send to us a list of the sites (URL information) for the relevant PSRC reports.

It was noted that many disturbance-recording devices were available, but that there are few systems to harmonize the data. Use of corporate WAN networks for data review and dissemination was discussed, but problems of security and confidentiality must be overcome. The owners and operators of the measurement units are often not the users of the data. John Kehler mentioned a "drop-chute" system where not-quite-real-time data was packaged and sent out to recipients, but no external access was allowed to request data. [John Kehler should be asked for more information about this system for inclusion in the minutes or report]. It was noted that AEP freely shares data after it is several days old, considering it to be of no commercial value at that point. Some question about the sampling rate and format of this type of available data was raised.

Jeff Dagle has a CD of software tools for integrating data from different recorders and performing analysis and monitoring for transmission reliability. These tools are part of an effort by the CERTS (CONSORTIUM FOR ELECTRIC RELIABILITY TECHNOLOGY SOLUTIONS), which is funded in part by DOE and California Energy Commission. Because of this, they have a WSCC focus, but should be well developed.

The need for generic descriptions and specifications of available (working) equipment was put forward to the attending vendors and requests must be sent out to those not in attendance.

John Kehler mentioned a Measurement Validation and Audit System (MVAS) used in WSCC, which should be reviewed and referenced [action item for John to send specs].

Bharat Bhargava volunteered to send details of Southern California Edison's monitoring experience.

Alex Golder volunteered to send specifications for his system and a reference list of his clients, to gather their experience.

Baj Agrawal offered to provide the WSCC monitoring requirements and specifications. Facilities >1000 MW and 'key' substations are monitored.

Jim Ingleson volunteered to provide a write-up on site selection. A figure of merit was assigned to utilities that have tested their underfrequency load shedding schemes and have some experience in validating their site selections. Recognition of evolution of power systems is required, so that sites are not kept purely for historical reasons.

It was agreed that material from panel sessions in 1999 and 1993 should also be added to the WG report.

Alex Golder presented experience from Australia using their quasi-continuous modal monitoring system.  His presentation indicated that continuous recording of mode frequency and damping gave a different picture than snap-shots during disturbances.
