Changing the Voltage Thresholds for the Generator

The voltage thresholds determine the range within which 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 voltage thresholds leads to disconnection of the line conductor from the stand-alone grid or 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 > Voltage monitoring.
  2. Set the parameter Voltage monit. gener. lower minimum threshold to the minimum generator voltage.
  3. Set the parameter Voltage monit. gener. upper maximum threshold to the maximum generator voltage.
