IM3 CT INPUT
Mains I/E active power (Pm) is measured and calculated from controller’s Im3
current terminal. The value is multiplied by 3 to estimate the aggregate mains
power.
ANALOG INPUT
Mains I/E active power is measured by an external device and the controller
measures this value via analog input LdCtrl:I/E-Pm.
Hint:
Earth fault current protection may be used only if I/E-Pm meas = ANALOG INPUT or NONE.
I/E-Qm meas [ NONE / IM3 CT INPUT / ANALOG INPUT ]
Import / Export measurement selection when one of PF I/E modes selected.
NONE
No source for I/E reactive power measurement available. If selected, power factor
control defaults to BasePF.
IM3 CT INPUT
Mains I/E reactive power (Qm) is measured and calculated from controller’s Im3
current terminal. The value is multiplied by 3 to estimate the aggregate mains
reactive power.
ANALOG INPUT
Mains I/E reactive power is measured by an external device and the controller
measures this value via analog input PFCtrl:I/E-Qm.
Hint:
Earth fault current protection may be used only if I/E-Qm meas = ANALOG INPUT or NONE.
If I/E-Pm meas is set to IM3 CT INPUT, then I/E-Qm meas should be logically set to IM3 CT INPUT as well,
because IM3 CT INPUT is common input for both parameters.
Import load [ kW – MW* ]
Requested power from / to mains when LoadCtrl PtM = IMP/EXP or when Export protection function is active
i.e. Export limit = ENABLED.
Step: 0,1 kW / 1 kW / 0,01 MW*
Range: -320,0 MW to +320,0 MW*
*Note:
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual).
PeakLevelStart [ kW – MW* ] (FV)
Load consumption level the gen-set has to stop at. Function is inactive when PeakAutS/Sdel = OFF. Genset
start is PeakAutS/Sdel delayed after the consumption of the Load exceeds the PeakLevelStart limit.
Step: 0,1 kW / 1 kW / 0,01 MW*
Range: PeakLevelStop to 320,0 MW*
Force value possibility: Yes
*Note:
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual).
PeakLevelStop [ kW – MW* ] (FV)
Load consumption level the gen-set has to start at. Genset stop is PeakAutS/Sdel delayed after
PeakLevelStop limit is reached. Load consumption (P factory) is calculated (not directly measured) as a sum
of gen-set (Act power) and mains (P mains) active power.
Step: 0,1 kW / 1 kW / 0,01 MW*
Range: 0 to PeakLevelStart MW*
Force value possibility: Yes
*Note:
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual).
PeakAutS/S del [ s ] (FV)
Delay for automatic Peak start/stop function. Set to zero to disable Peak aut start function.
Step: 1s
Range: OFF, 0 – 3200 s
Force value possibility: Yes
