"Reactive Power

General
In addition to the four points, the following parameters also come into play:
Parameter Range of val-
ues
-1 ‑ 1
"Offset Factor"
0 s ‑ 60 s
"Initial Delay
Time"
0 % ‑ 120 %
"Lock-In P-De-
pendent (% of
Nominal Appar-
ent Power)"
0 % ‑ 100%
"Lock-Out P-
Dependent (%
of Nominal Ap-
parent Power)"
Range of val- Description
ues
50 % ‑ 150 %
AC voltage in percent [%] re-
lated to the nominal voltage
(X‑axis).
-100 % ‑ 100 %
Reactive power in percent [%]
related to the nominal appar-
ent power S
Description
Shift of the Q(U)
characteristic on the
Y‑axis (Q‑axis) via an
offset factor. The
offset factor is re-
lated to the reactive
power set in point 1
or point 4, by which
the characteristic
curve continues to
be limited.
Start-up delay in
seconds [s] - Delays
the start of the Q(U)
control when leaving
the voltage range
between the data
point 2 and the data
point 3.
Effective power in
percent [%] related
to the nominal ap-
parent power S . If
n
this value is ex-
ceeded, the Q(P)
characteristic is ac-
tivated.
Effective power in
percent [%] related
to the nominal ap-
parent power S . If
N
this value is under-
shot, the Q(P) char-
acteristic is deactiv-
ated. The lock-out
limit has priority
over the lock-in limit.

Supplementary de-
scription
With the power-de-
pendent Lock-In/
Lock-Out values, it
can be set that the
Q(U) control is deac-
tivated at low
powers.
The different values
for activation (Lock-
In) and deactivation
(Lock-Out) enable a
hysteresis to avoid
unintentionally fre-
quent switching
on/off of the func-
tion. For this, the
Lock-In value must
be greater than the
Lock-Out value.
