C4 System Technical Performance

Further Revised Scope:
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 areas on which the activity is carried out are:




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. The above points certainly relate
also to the emerging Smart Grids technology, with particular emphasis concerning Power
Quality and Advanced Tools for the analysis of power system transients and dynamic
performance.

Areas of Interest

Power Quality:
Benchmarking of PQ performance; Compatibility levels and Indices; Measuring and monitoring;

SVC, arc furnaces); Immunity of installations.


transformers, with reference to transformer energization studies; Resonance and Ferro resonance;
interaction between long AC cables and the system; influence of system conditions and characteristics
on CBs operation, such as TRVs; Insulator pollution influence on the system performance.

Lightning:
Critical review parameter statistics; Attachment process; Lightning performance of distribution and
transmission lines with reference to the application of line arresters; Low Voltage lines protection;
Protection of wind generators; lightning location systems data application.

Advanced Tools for the analysis of power system performance:
Numerical EM analysis for surge propagation studies; Numerical techniques for the computation from
steady‐state to very fast front transients; modelling unsymmetrical conditions of power systems.

Power systems dynamic performance models and analysis:
Power balancing assessments; Influence of power converters and HVDC transmission on system
security and AC network performances; Methods for modelling and aggregation of loads in active
power networks;

SC-C4 New Strategic Plan

In organising the SC C4 activities and
workforce, it is important to recognise the
following key features of its scope:


It brings together all activities related to the system
"technical" performance under one study committee,
thus providing for the coordination and integration of
these activities.
The study of the phenomena considered requires a
high degree of specialist knowledge and experience
related to characteristics and performance of individual
components as well as the integrated power system.

AG C4.2 - Liaisons

The Goal of AG C4.2 – Liaisons:

From Strategic plan for C4:


"Maximising the potential of the links that exist with external organisations,
such as CIRED, IEC, Eurelectric and IEEE, as well as through internal
coordination with the other CIGRE Study Committees"
Interaction with other technical organisations is essential for
identifying and effectively dealing with emerging system
performance problems. Additionally, CIGRE has the important role
of providing the scientific and technical knowledge base on which
new standards are developed by international organisations such
as IEC. In this context, SC C4 intends to work collaboratively as
appropriate with the following organisations: IEC, CIRED, IEEE,
Cenelec, Eurelectric
