This setpoint is used to select, which method is used for measurement of the
active power (P) transported from busL to busR. Positive measured value
means that power is transmitted from busL to busR, negative value means
the opposite.
NONE: Active power from the busL is not measured. IM-NT controller
will not influence gen-sets on the bus even if BTB is closed.
CT INPUTS: Active power from the busL is calculated from the busL
L-N voltages and busL currents measured at the controller CT
terminals.
ANALOG INPUT: Active power from the busL is measured by an
external device and passed the controller via analog input MLC:I/E-
PbL.
This setpoint is used to select, which method is used for measurement of the
reactive power (Q) transported from busL to busR. Positive measured value
means that power is transmitted from busL to busR, negative value means
the opposite.
NONE: Reactive power from the busL is not measured.
NOTE:
It is possible to perform import/export load control without reactive
power measurement, i.e. based on active power measuement only.
The gen-sets group power factor will be maintained at constant level
given by #SysPwrFactor setpoint. However, this kind of operation in
certain conditions may cause bad power factor values.
CT INPUTS: Reactive power from the mains is calculated from the
busL L-N voltages and busL currents measured at the controller CT
terminals.
ANALOG INPUT: Rective power from the busL is measured by an
external device and passed the controller via analog input MPF:I/E-
QbL.
NOTE:
If the reactive power is measured, then the measurement method should
match the method used for active power measurement, i.e. if the setpoint I/E-
PbL meas is set to CT INPUTS, the I/E-QbL meas should not be set to
ANALOG INPUT and vice versa.
