Range:
#%LdResStrt 1 (2,3,4)
– 110 %
Hint:
If additional Minimum Running Power system is used, the engine might not stop even if required by load
reserves. Yet another conditions must be fulfilled in this case.
!!! IMPORTANT !!!
Reserve for stop always has to be higher than corresponding reserve for start for all Power Management
modes !
#NextStrt del
[ s ]
The delay before next gen-set start-up in Pwr management. Delay is not used, when the first gen-set(s)
starts.
Step:
1
s
Range:
0 – 3600 s
#OverldNextDel
[ s ]
The delay before next gen-set start-up in Pwr management when the system load is equal or higher than
90% of nominal power of all gen-sets on the bus.
Delay is not used, when the first gen-set(s) starts. Delay is used only when in island parallel operation, not in
mains parallel.
Step:
1
s
Range:
0 – 3600 s
#NextStopDel
[ s ]
The delay before next gen-set stopping in Pwr management. When delay is elapsed, the gen-set starts soft
unload, opens GCB, cools down and stops.
Step:
1
s
Range:
0 – 36000 s
#SlowStopDel
[ s ]
When the Slow stop protection occurs, the controller announces to the rest of the system, that the engine is
no more ready.
a) If there are another sets ready to start and supply the load, the protection waits until the substitute engine
starts and connects to the bus. Then the engine with the active Slow stop protection softly unloads, cools
down and stops. The controller waits for substitute engine max for
#SlowStopDel
time.
b) If there is no other set to start, the protection activates immediately. If soft unload possible (another set is
running or MCB is closed) engine is softly unloaded, if not, GCB opens immediately.
As every protection it has to be reset by operator to get ready again.
Step:

s
Range:
0 – 600 s
#MinRunPower 1 (2, 3)[ kW – MW* ]
It is minimum required power of gen-set group (sum of
Nomin power
of running gen-sets). When Binary input
Sys start/stop is closed, starts and stays running such a number of gen-sets to keep selected
#MinRunPower X
value. This is independent on load reserves system, so even if there is high load reserve
that would allow to stop some engines, Minimum Running Power system may force them to keep running.
When binary input MinRunPower X is closed, the corresponding
#MinRun power X
value is selected. When
more binary inputs MinRunPower X are closed, the higher number has higher priority. When no input closed,
no
#MinRunPower X
is selected and minimum running power is zero, leaving only the load reserves system
to work.
Step:
0,1 kW / 1 kW / 0,01 MW*
Range:
0,0 kW – 650,00 MW
*Note:
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual).
Hint:
An engine will be stopped only if the sum of remaining gen-sets’ nominal powers is higher or equal to
#MinRunPower X
level.
