FORCED OPERATION (Kerys in “AUTO” mode)
(temporary outward and return coupling)
Start of FORCED OPERATION
•
Generating set start request.
•
The generating set voltage and speed increase.
•
When the generating set is stabilised in speed and voltage, synchronisation of the generating set to the grid is requested.
•
After synchronisation, the generating set power unit is switched off.
•
Transfer of the active and reactive power from the grid to the generating set according to a predetermined ramp. The ramp
does not exceed 10 seconds for transfer of the generating set’s rated output. The generating set power unit is disconnected
when the power on the generating set reaches the lower limit.
•
Power unit switched on, grid side.
The installation is supplied by the generating set
End of FORCED OPERATION
•
Opening of the forced operation order.
•
Synchronisation of the generating set to the grid.
•
Grid power unit switched off.
•
Transfer of the generating set’s active and reactive power to the grid.
•
Generating set power unit switched on.
•
Cooling
delay.
•
Generating set stopped and set to standby.
The Kerys remains in “AUTO” mode
The installation is supplied by the grid
Manual generating set operation
This mode of operation is selected with the “MANU” key. The operator is able to start and stop the generating set via the MMI keypad.
The power unit is switched off manually with the manual synchronisation of the generating set to the grid using the keys
“+ F”, “- F”, “+V”, “-V”, the load transfer remains automatic. The safety devices of the generating set remain active in this mode of
operation.
This mode of operation is the responsibility of the operator
