Spread Spectrum Radio for Relaying?
John Tengdin, Editor-in-Chief
July 2001
At the May Power System Relaying Committee meeting,
a new working group was formed to address the issue – “Use of Spread
Spectrum Radio for Protective Relaying”. The initial meeting was heavily
attended, with over fifty engineers participating in the discussions. Real
progress was made at the double session, with agreement on the assignment of
this new H2 working group (develop a Working Group Report/PSRC Web Publication),
and on the scope and purpose of the document. Even more important was the
agreement on a draft detailed outline for the report.
Here are some of the details:
Title:
Using Spread Spectrum Radio Communication for Power System Protection
Relaying Applications
Scope:
This
project will develop a document for the application of protective relays using
spread spectrum radio communication for power system protection schemes. It will
present background information, bibliography, and recommendations. It discusses
spread spectrum radio communication technologies and topologies that may be
applicable for use in protective relay schemes. It discusses practical
considerations of interfaces, interoperability, reliability (security and
dependability), availability, security against intrusion, and economics for
spread spectrum radio communication.
Purpose:
There is currently no IEEE document describing the application of protective
relays using spread spectrum radio communication. Protective relaying and spread
spectrum radio communication technologies are rapidly changing and expanding.
Understanding the opportunities and limits of these technologies is important to
their successful mutual application. This document will be coordinated with the
Audio Tone Guide to minimize duplication of effort. This document will provide
information to assist in the application of spread spectrum radio communication
technologies for protective relay schemes. Descriptions of some working systems
and their performance will be provided.
The detailed draft outline for the document is available on the PSRC web site
under Working Group H2. The outline recognizes the previous work done in PSRC
Working Group H5 in defining peer to peer applications, and in Working Group H4
in developing communication test scenarios for a representative set of those
applications.
This document will be an extremely valuable tool for anyone contemplating the
use of spread spectrum radio for protective relaying. Its preparation will
require input from many parties. If you have an interest in this topic, plan to
attend the next meeting of H2 on September 19 during the fall PSRC meeting
September 17-20 at the Madison Concourse Hotel, Madison, WI. The
cut-off date for reservations is August 20, 2001. The PSRC room block is limited
and there are no additional rooms available; therefore, it is important that you
make your reservations early and definitely before the cut-off date.
This will be the regular fall
joint meeting with the C0 working groups of the Substations Committee, so it will be a busy
time.
If
you can’t make the meeting and still want to help on this document, contact

It’s
time to get involved!
