C4 System Technical Performance
Scope further revised:
SC C4 deals with methods and tools for analysis related to power
systems, with particular reference to dynamic and transient conditions
and to the interaction between the power system and its
apparatus/sub-systems, between the power system and external
causes of stress and between the power system and other
installations. Specific issues related to the design and manufacturing
of components and apparatus are not in the scopes of SC C4, as well
as those specifically related to planning and operation and control,
apart from those cases in which component/apparatus/subsystem
behaviour depends on, or significantly interacts with, the performance
of the nearby power system.
The fields on which the activity is carried include but are not limited to:






Power Quality,
Electromagnetic Compatibility/Electromagnetic Interference (EMC/EMI),
Insulation coordination,
Lightning,
Advanced Tools for the analysis of power system performance,
Power systems dynamic performance models and analysis.

Revised Strategic Plan for C4
The proposal is for collapsing into three groups:
 􀂃 One strategic/technical advisory group
 􀂃 One advisory group to liaise with other SC’s
and institutions (IEEE, IEC, CIRED etc.)
 􀂃 One advisory group to help with the
dissemination of SC C4 achievements/results,
namely to help with the organizing of tutorials,
workshops, etc.

New structure – General concerns

Some subjects may phase out if we do not properly focus on it. One way to
address this is to have a balanced number of experts from each area in the
technical AG.

A contrasting comment was that we do not want to be too narrow in defining our
scope, because maybe in the current structure we are limiting our selves and not
including new areas.

It was expressed that this new approach is fruitful as it would allow more
efficiency and greater interaction between the various technical areas

There is a concern about how big the single technical AG can be (practically) to
be able to get a balanced view across the fields and still be effective.

Another concern is that the scope of the subjects we deal with is too wide and so
there is no best way to deal with a structure for such a committee so should we
also deal with this issue.

The overlap between the subject matters was thought by a few individuals to be
perhaps 10-20% and so we may be going too far to collapse everything into a
single technical group.

In our group we have too broad areas (i) methods and (ii) tools; so maybe we can
have two technical groups in these areas.


It seems superfluous to have the organizational AGs on liaisons and tutorials.
Maybe we should have two subcommittees (i) electromagnetic phenomena, and
(ii) electromechanical phenomena, i.e. based on frequency range of phenomena.
