The function of the controller is designed to handle the maximum sum of nominal power at 32000kW
(3200.0kW, 320.00MW depending on the power format in the controller). If the sum of nominal power
of all gen-sets connected to the intercontroller CAN exceeds these values the power format needs to
be changed accordingly.
E
XAMPLE
:
There are 20 gen-sets each with 2000kW of nominal power. The sum of the nominal power is
40000kW. Therefore the power format in kW cannot be used because the sum exceeds 32767.
Therefore power format in MW needs to be chosen because the sum in MW is 40MW (it does not
exceeds 320.00MW).

Basic Power management
The setpoint
Pwr management:
Pwr management
enables and disables the gen-set to be active
within the power management and makes automatic load dependent starts and stops. If the power
management is disabled, the start and stop of the gen-set do not depend on the load of the group. If
the gen-set remains in AUT mode, the running condition depends only on the binary input
Sys
start/stop
.
The binary input
Sys start/stop
requests the gen-set to start or stop. If the input is not active, the gen-
set stops with delay
Pwr management:
#SysAMFstopDel
after the input has been deactivated and
will not start again if in AUT mode. If the input is activated again, the delay
Pwr management:
#SysAMFstrtDel
starts to count down. Once the delay elapsed (+0.5s because of compatibility
reasons with Load Demand Swapping), the gen-set is activated and can be started by the power
management. In other words, the power management is activated only if the binary input Sys
start/stop is activated, the option of setpoint
Pwr management:
Pwr management
= ENABLED and
the AUT mode are selected.
N
OTE
:
The gen-set takes part of the power management (= is active) only if the controller is in AUT mode!
N
OTE
:
The gen-set performs load and VAR sharing whenever it is connected to the bus bar i.e. it is
independent on whether the controller is in AUT or MAN mode or whether the power management is
active or not. Do not confuse power management with load sharing.
