NEPLAN | Voltage Quality

back to overview

Decreasing short circuit power, increase in consumers and generators with power electronics devices and decrease in network damping can lead to deterioration of the voltage quality in electrical networks.


NEPLAN helps distribution system utilities analyze and solve voltage quality problems with a variety of powerful modules:

  • Flicker Analysis
  • Harmonic Analysis
  • Load Flow Calculation (symmetrical and unsymmetrical)
  • Dynamic Analysis
