  • Introduction to flicker and its calculation in PowerFactory.
  • Short and long term flicker severity for continuous and switching operation including voltage change.

PF-08-07 - Envelope curve of the network impedance

  • Simplified representation of the network impedance by an envelope curve to model the first parallel resonance of the network.

PF-08-08 - Network impedance loci

  • Consideration of possible network behaviour in the frequency domain with respect to resistance and reactance of the network impedance for various system states using impedance loci.

PF-08-09 - Voltage unbalance

  • Defining voltage unbalance.
  • Causes and effects of voltage unbalance.
  • Practical definitions of voltage unbalance.
  • Unbalanced system modelling in PowerFactory.
