Settings for “Q(U) “
Note:
Voltage-dependent control Q(U)
regulates the reactive power output
depending on the voltage.
4 coordinates can be set in order to map the
curve.
Open menu <Setting for>.
1.
Select <Q(U) Setting>.
2. Define U/Un, Q/Sn and phase for each
of the 4 coordinates.
3. Define <Activating power> as a % of Pn.
Note: Activation threshold as a percentage
of Pn corresponds to the “Lock-In” voltage.
3. Define <Deactivating power> as a % of
Pn.
Note: Deactivation threshold as a
percentage of Pn corresponds to the
“Lock-Out” voltage.

Define Q(U) parameters
Definition:
The coordinates are the voltage as a
percentage of Un and the reactive power as a
percentage of Pn.
A grid operator can specify two active power
thresholds as a percentage of Un to activate
or deactivate the function. The active power
thresholds are normally referred to as the
“Lock-In” and the “Lock-Out” active power.
