Setpoint: #%LdResStop 4
This setpoint is used to adjust the load reserve for stop in relative mode. i.e. Pwr
mgmt mode = REL (%) if the reserve set #4 is active. Learn more about reserves
in the chapter Reserves, minimal running power.
The currently active reserve set is selected by binary inputs Load res 2, Load res
3 and Load res 4. If none of these inputs is active the set #1 is selected.
NOTE:
The reserve for stop must be always adjusted higher than the reserve for start.
Setpoint: #NextStrt Del
This setpoint is used to adjust the delay of starting the next gen-set when the
actual load reserve drops below the adjusted reserve for start, but the group is still
not overloaded.
Setpoint: ##OverldNextDel
If the system reserve drops below the start limit for next gen-set the delay
#NextStrt del will begin to count down. But if the load raises too quickly it might
happen that the system gets overloaded already before the delay #NextStrt del
reaches zero.
This setpoint is used to prevent this situation. If the #NextStrt del timer is already
counting down (i.e. the condition for starting of next gen-set based on reserves is
fullfiled), the total load of running gen-sets reaches 90% of their nominal capacity
and the remaining time of the running timer is higher than #OverldNextDel, the
running timer is shortened to the value of #OverldNextDel to speed up the start-up
of the next gen-set.
NOTE:
The setpoint takes place only in island operation.
