Multi-line 2 General Guidelines for Commissioning

Resulting speed/voltage curve upon load change

Testing is easily done by using (if possible) a load bank applying 'jumps' in the generator load,
thus testing the speed/voltage control.
The optimum result is indicated by this curve:
As indicated, 2-3 'overshoots' before stabilising after a sudden change is OK. If more
'overshoots' are present, then decrease the K factor and try again.
