2014 Meeting Minutes

  1. Introduction and presentation of the Committee. Schedule of the proposed agenda for the meeting was presented and accepted. Minutes from 2013 meeting were reviewed and accepted.
  1. Scope of the DMWG was read and discussed; no comments or concerns were raised.
  1. Liaison Reports:
  2. Ken Martin (EPG), liaison for the PSRC, gave the following PSRC updates:
  3. In 2011, a revision to the IEEE C37.118 Synchrophasor standard was finished. New standard is composed of two parts, C37.118.1 and C37.118.2.
  4. In May 2014, an amendment was made to C37.118.1 due to unachievable requirements. Amendment was published, titled C37.118.1a.
  5. In 2013, IEEE C37.244-2013 “IEEE Guide for Phasor Data Concentrator Requirements for Power System Protection, Control, and Monitoring” was published. Now this guide is moving towards becoming an IEEE standard.
  6. In 2013, IEEE C37.242-2013 “IEEE Guide for Synchronization, Calibration, Testing, and Installation of Phasor Measurement Units (PMUs) for Power System Protection and Control” was published.
  7. Lots of discussion about ROCOF (Rate of Change of Frequency) was had. It was discussed that ROCOF will become more important in the future for some control schemes, and require more test/accuracy requirements. Ken agreed, but more industry research is needed on where to go with ROCOF and how to define these requirements.
  1. No liaison for PSIMC was in attendance, but Gert Rietveld (VSL) did mention there was a PSIM Committee meeting on the morning of Wednesday July 30, 2014.

Scope: Development of procedures, methods and techniques for detecting, recording, and analyzing power system dynamic performance, for use in system controls, for event reconstruction, for validation of correct operation of equipment, controls, and protection, and for developing and improving simulation models. The Working Group (WG) will consider transducers, computation equipment and algorithms, communications, and other portions of systems for these measurements. The WG will disseminate its results appropriately, including use of panel sessions, technical paper sessions, and preparation of WG papers. The WG will coordinate its activities with other IEEE and CIGRE bodies, including the Power System Relaying Committee and the Power Systems Instrumentation and Measurements Committee.

History of the scope: It was developed by Richard Schulz in January, 1997 iterated with and improved by Carson Taylor, proposed to the newly formed Working Group at the Winter 1997 meeting in Columbus, Ohio. It was approved by the Power System Dynamic Performance Committee at that meeting. Richard Schulz was the chair of the working group for the first 10 years.

2014 PES GM Tutorial

Implementation of Synchrophasor Systems

Date:Wednesday July 30, 8:00 am-5:00 pm
Price:Early Bird $295, Regular $395. Student Early Bird $100, Student Regular $150
Instructors:Vahid Madani (Organizer and Chair), Alexander Apostolov, Gerald FitzPatrick, Allen R. Goldstein, Roger Hedding, Mital Kanabar, Roger King, Harold Kirkham, Zhenyu Huang, Ken Martin, Sakis Meliopoulos, Thomas Morris, R. Jay Murphy, Damir Novosel, Manu Parashar, Ravi Subramaniam

The distinction of PMU technology comes from its unique ability to provide synchronized phasor measurements of voltage and current signal from widely dispersed locations in an electric power grid. From a system reliability standpoint, these real-time measurements allow early identification of potential problems both locally and regionally. From a broader perspective, synchrophasor technology offers means to solve a growing number of challenges and has lot of scope in future, thus attracting the industries and research communities throughout the world. Recent investments in the Synchrophasor technology have energized the industry to demonstrate the long range promises.

IEEE PES Power System Relaying Committee and the North American Synchrophasor Initiative (NASPI) Performance Standards Task Team (PSTT) have leveraged expertise to present a tutorial on Synchrophasor systems Implementation.

This tutorial is intended for power system practitioners considering investment in synchrophasor technology and supporting business case for large scale deployment. In addition to the benefits enabled by the technology, some of the topics covered include phasors, synchronization mechanisms, computation processing and accuracy, phasor data concentrators (PDCs), and interoperability.

Relevant industry standards and guides, phasor data communication and archival, approaches and architectures to build wide-area measurement systems, and applications using synchrophasor data such as situational awareness, advanced warning systems, adaptive protection, state estimation, and voltage stability monitoring will be presented. The tutorial will also include a review of the IEEE guides for installation and testing of PMUs and PDCs, and the need for conformance to the standards and calibration of the entire measurement chain.

Synchrophasor Fundamentals and Applications: Leveraging the Investment (tutorial)

Tuesday, 23 July, 2013 8:00 AM-5:00 PM Renaissance Salon A

Sponsored By: IEEE PES and Power & Energy Education Committee

Tutorial Summary:

Instructors: Dan Brancaccio, Joe Chow, Fred L. Elmendorf, R. Matthew Gardner, ScottGhiocel, Kevin Jones, Innocent Kamwa, David M. Laverty, Ken Martin, Mario Paolone,Scott Stapels, James S. Thorp, Kjetil Uhlen, Luigi Vanfretti, Austin D. White

The past five years have seen an immense public and private interest, investment, andcooperation in the synchrophasor technology space. Many electric transmissionowners and operators in North America were awarded grants to deploy a great numberof PMUs across their respective service areas, along with the related communicationsand IT infrastructure.

The availability of this new infrastructure can enable the development andimplementation of new applications that utilize time-synchronized dynamicmeasurements. However, unless properly managed, challenges involved in designing,deploying, and operating and, ultimately, extracting value from this new capital- anddata-intensive synchrophasor infrastructure can be daunting. While the researchindicates tremendous value in leveraging synchrophasor technology, a divide stillexists between the current state of the technology and the possibilities thatsynchrophasor technology enable.

The purpose of this tutorial is to address the fundamentals of synchrophasortechnology and synchrophasor-enabled applications at a practical level. The tutorialwill be delivered by hands-on practitioners of the technology along with those in theresearch community. Covering topics across the spectrum of the technology space,the tutorial opens with a session on synchrophasor computation fundamentals,continues in sessions focusing on PMU installation and testing, designing IT andcommunications for synchrophasors, deploying synchrophasor applications from thelab to the field, managing the data, state estimation, and culminates in a session onsynchrophasor-based wide-area control implemented in a utility.
