Response to value falling below active power P
min
If the measured active power P
meas
falls below the set parameter P
min
, the
value U
min
is adopted as the desired value.
U
ref
= U
min
Response to a measured active power P
meas
= 0 MW:
If the measured active power P
meas
= 0, the set parameter U
0
is adopted.
U
ref
= U
0
Linear dependency with negative active power:
If the measured active power P
min
≤ P
meas
≤ 0, the desired value is calculated
using the following equation:
U
ref
=
U
0
- U
min
0 - P
min
× P
meas
+ U
0
Linear dependency with positive active power:
If the measured active power 0 ≤ P
meas
≤ P
max
, the desired value is calculated
using the following equation:
U
ref
=
U
max
- U
0
P
max
× P
meas
+ U
0
To activate the active power-dependent adjustment of the desired voltage
value, you need to set the following parameters:
Activating TDSC
The TDSC function is only active when the device can calculate the active
power (correct current measurement and voltage measurement) and the re-
quired parameters are set. If this is not the case, voltage regulation is in ac-
cordance with the set desired value. You can activate or deactivate the
power-dependent adjustment of the desired voltage value as follows:
▪ Parameter
▪ Digital inputs TDSC on and TDSC off
If you activate TDSC, the line drop compensation (R&X compensation or Z
compensation) function is deactivated.
