Mission

To facilitate and promote the progress of engineering and the international exchange of information and knowledge in the field of system technical performance. To add value to this information and knowledge by means of synthesizing state-of-the-art practices and developing recommendations.

Scope

Study Committee C4 is responsible for advanced methods and tools for analysis related to power systems.

Areas of attention include:

• Power Quality Performance: Continuity of end-to-end electric power supply
and voltage waveform quality (magnitude, frequency, symmetry). Analysis
covers emission assessments from disturbing installations, measurement
and simulation methods, identification of quality indices, monitoring
techniques, immunity of sensitive installations, and mitigation techniques
taking into account a co-ordinated approach across all voltage levels.
• Electromagnetic Compatibility (EMC): High frequency disturbances
on the end-toend electricity supply and all disturbances (HF or LF)
reaching equipment other than through the electricity supply. Studies
include measurement and simulation methods. Health effects related
to low frequency EMF are however excluded.
• Power System Dynamics: Development of advanced tools and new
analytical techniques for assessment of power system dynamic/transient
performance, security, design of controls and modelling of existing and
new equipment, real time stability evaluation and control.
• Lightning: Analysis of lightning characteristics and interactions of
lightning with electric power systems and equipment, including
protection in MV and LV networks against lightning, and their standardisation.
• Insulation Co-ordination: Methods and tools for insulation co-ordination
and electromagnetic transient analysis in electric power systems and
equipment, contributing to optimisation of their cost and reliability.
