Power Quality

The consequences of poor power quality are very different. In theory, an ideal power supply is always available and has

  • a constant frequency (50 Hz or 60 Hz),
  • ideal sinusoidal currents and voltages,
  • a constant mains voltage (230 V, 400 V) and
  • no voltage dips or interruptions.

 
In reality, the increasing use of power electronics will stress the mains grids non-linearly.

That leads to

  • Distortions of the waveform (harmonics),
  • Over- and under-voltages above the 10% tolerance limit,
  • partly total failures of the supply voltage
  • and causes visible fluctuations in lighting (flicker).


With this background, the cooperation network focuses on the following topics:

Actual Topics

  • reduction of grid disturbances
  • grid-friendly loads (example compressor drive)
  • decentralized voltage stabilization
  • modeling and parameter identification of grid structures
  • calibration of high current sensors
