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.
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.
Linear dependency with negative active power:
If the measured active power P
min
≤ P
meas
≤ 0, the desired value is calculated
using the following formula:
Linear dependency with positive active power:
If the measured active power 0 ≤ P
meas
≤ P
max
, the desired value is calculated
using the following formula:
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 isn't done, the voltage is regulated to the
set desired value 1/2/3 [
Section 7.3.1.2, Page 98]. You can activate or de-
activate the power-dependent adjustment of the desired voltage value as fol-
lows:
▪ Parameter
▪ Digital inputs
TDSC on
and
TDSC off
(optional)
▪ Control system command (optional)
