11.2.1.10 Setpoint: I/E-Pm meas
Group Process Control
Range [units] NONE, CT INPUTS, ANALOG INPUT [-]
Related FW standard v3.1.0
Description This setpoint is used to select, which method is used for measurement of the
active power (P) imported from the mains.

NONE: Active power from the mains is not measured.

CT INPUTS: Active power from the mains is calculated from the
mains L-N voltages and mains currents measured at the controller
CT terminals.

ANALOG INPUT: Active power from the mains is measured by an
external device and passed the controller via analog input

:
If the active power is measured, then the measurement method should match
the method used for reactive power measurement, i.e. if the setpoint
I/E-Pm
meas is set to CT INPUTS, the I/E-Qm meas should not be set to ANALOG
INPUT and vice versa. If the setting differs, the measurement for both active
and reactive power are both taken from CT input. Setting NONE can be used
in any combination without changing the setting of the second measurement.
11.2.1.11 Setpoint: I/E-Qm meas
Group Process Control
Range [units] NONE, CT INPUTS, ANALOG INPUT [-]
Related FW standard v3.1.0
Description This setpoint is used to select, which method is used for measurement of the
reactive power (Q) imported from the mains.

NONE: Reactive power from the mains is not measured.
N
OTE
:
It is possible to perform import/export load control without reactive
power measurement, i.e. based on active power measuement only.
The gen-set 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 at the mains.

CT INPUTS: Reactive power from the mains is calculated from the
mains L-N voltages and mains currents measured at the controller
CT terminals.

ANALOG INPUT: Rective power from the mains is measured by an
external device and passed the controller via analog input
