IEEE PES Summer 2002 Meeting |
P1159.1 PQ Measurement & Characterization Task Force |
Randy Collins, chair
of 1159, opened the Summer 2002 meeting of the IEEE 1159.1 TaskForce on July
22, 2002 at 15:00 in the Palmer House Hilton, Chicago, Illinois, with a
communication from Alex McEachern, chair of 1159.1, that he was unable to
attend this meeting, and was resigning as chair of the task force. Randy requested that the secretary of 1159
forward the 1159 committee’s thanks to Alex for his efforts. The history of the taskforce and its efforts
and directions since the first meeting in 1996 were reviewed. The revised PAR that followed the combining
of 1159.1 and 1159.2 is set to expire in a year. Given all of that, the need to move forward with a new chair person
was emphasized. Charles Perry, of EPRI
PEAC, was approved by the unanimous vote to replace Alex.
The discussion
focused initially on the adopting IEC 1000-4-30 (which is through most of the
IEC balloting and approval process) as the basis and put a “wrapper” around it
with noted exceptions and additions.
Comments ranged from “the rest of the world will be using it” --to-- “it
is better than nothing” --to-- “why should we put our approval on something
full of holes”.
The suggestion was
then made to focus on one section that would have the most compatibility and
utilize the efforts from the 1159.2 taskforce on characterization of sags. Section 5.4 of the 1000-4-30 was reviewed
and the measurement requirements were outlined, relative to the 2.0 element of
the IEEE 1159 Table of PQ Phenomena called Short Duration RMS Variations. This information will be combined with the
last 1159.2 documentation and forwarded to the taskforce in August for comment.
It was also suggested
and approved to change the use of p.u. to percent, in another effort of
harmonization with the IEC. Lastly, as
there is no equivalent effort in an IEEE commitment on the measurement
requirements of harmonics, the adopting of IEC 61000-4-7 will be closely
reviewed and reported by E.Gunther.
Next task force
meeting will be in LasVegas at the T&D meeting in January 2003. Meeting was adjourned at 17:00.
