Changing the Frequency Thresholds of the Generator Voltage

The frequency thresholds determine the range within which the frequency of the generator voltage is allowed to fluctuate. When the Sunny Island switches to the generator, the stand-alone grid will also fluctuate within this range.

A breach of the set frequency thresholds leads to disconnection of the line conductor from the stand-alone grid or to the generator not being switched on.

The basic procedure for changing operating parameters is explained in another section Changing Operating Parameters).

Procedure:

  1. Select Generator > Generator.
  2. Set the parameter Generator nominal frequency to the rated frequency of the generator voltage.
  3. Select Generator > Generator > Frequency monitoring.
  4. Set the parameter Frequency monit. generator lower minimum threshold to the minimum frequency of the generator voltage.
  5. Set the parameter Frequency monit. generator without max. threshold to the maximum frequency of the generator voltage.
