Active and Reactive Power control modes (MINT application only)
System Base load
Gen-set group is controlled on constant (or adjustable) power. The Baseload value can by changed by
setpoint or via analog input.
Important setpoints: ProcCtrlMulti: #SysLdCtrlPtM = BASELOAD; #SysBaseload; SysBaseLdMode.
Local Baseload
Selected gen-set from island or mains parallel running group can be loaded to constant LocalBaseload
value. This engine is taken out from Load sharing and Power management. LocalBaseload value is reduced
only when common group (actual) load is lower than this value. The gen-sets in the group will try to match
their LocalBaseloads (when more than one) based on their controller addresses, so the first limited would be
the one with the highest CAN address. I.e. this function will switch-off automatically in one or more
controllers if there is not enough load to cover all the requested LocalBaseloads.
Important setpoints: ProcCtrlMulti: LocalBaseload.
System Base power factor
Gen-set group is controlled in mains parallel to keep a constant (or adjustable) power factor.
Important setpoints: ProcCtrlMulti: #SysPFCtrlPtM = BASEPF; #SysPwrFactor.
Import-Export
Gen-set group is controlled to keep constant (or adjustable) Import or Export value. The external controller
InteliMains NT must be connected on the CAN2 to control gen-set group kW I/E.
Important setpoints: ProcCtrlMulti: #SysLdCtrlPtM = LDSHARING.
Import/Export power factor
Gen-set group is controlled to keep constant (or adjustable) Import or Export power factor.
Important setpoints: ProcCtrlMulti: #SysLdCtrlPtM = VSHARING. The external InteliMains NT controller
must be connected on the CAN2 to control gen-set group PF I/E.
Power management (MINT application only)
Automatic gen-set start / stop function based on load changes and/or Running hours or Engine size.
Following functions are available:
Power management in kW
Guarantees adjustable load reserve (load step) in kW. Suitable for load demand-based optimization.
Activation: Pwr management:#Pwr mgmt mode = ABS (kW)
Power management in kVA
Guarantees adjustable load reserve (load step) in kVA. Suitable for generator- or busbar dimensioning-
based optimization.
Activation: Pwr management:#Pwr mgmt mode = ABS (kVA)
