C4 system technical performance

C4 System Technical Performance

  • SC C4 Annual 2009 Meeting:

    • Held in Kuschiro Japan, June 12th, 2009

  • Revised scope:

    SC C4 is responsible for 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 scope of SC C4, apart from those cases in which component/apparatus/subsystem behavior depends on, or significantly interacts with, the performance of the nearby power system.


Sc subject area

SC Subject Area:

  • Power Quality →PQ contracting; Reliability improvement assessment; Sustainable technical performance – measures and reporting.

  • EMC/EMI → Influence of power installations on other installations; The ELF magnetic fields: characteristics and mitigation methods; EM vulnerability.

  • Insulation coordination → Critical review of existing practice; UHV systems; Oil filled transformers; Fast transients: interaction between system and transformers.

  • Lightning → Critical review of lightning parameter; statistics; attachment process; correlation between lightning and voltage dips; protection of wind generators

  • “Transversal” subjects → Advanced theories/tools for surge propagation studies and for dynamic performance assessment.

  • Power systems dynamic performance models and analysis →Tools for power balancing assessments; Risk-based security assessment .
