Active Power

Voltage-dependent Power Control
or also called Volt/Watt function or P(U) function, causes a change in effective
power depending on the mains voltage. By reducing the effective power at high
mains voltage (or increasing the effective power at low mains voltage), an unin-
tentional switch-off of the inverter due to the overvoltage or undervoltage limits
can be avoided. This makes the yield losses less than they would be if the inverter
was switched off.

Description
Voltage threshold (in % of
nominal voltage) that must
be exceeded or fallen be-
low to activate VFRT re-
gion 3 and its associated
current inrush mode.
- > 100 % ... Region 3 is
used as HighVoltage-
Disturbance Region.
- < 100 % ... Region 3 is
used as LowVoltage-
Disturbance Region.
Setting condition:
Threshold R1 > Threshold
R2 > Threshold R3
Default value 0 % means
that region 3 is deactiv-
ated /ineffective.
Multiplication factor (k-
factor) for the positive-se-
quence system reactive
current in region 3.
Only applied with current
inrush mode "Active Sym-
metric Current" and "Act-
ive Asymmetric Current".
Multiplication factor (k-
factor) for the negative-
sequence system reactive
current in region 3.
Only applied with current
inrush mode "Active
Asymmetric Current". If
an asymmetrical feed is
required, this is usually set
to the same value as "k-
factor Positive Sequence".
If symmetrical supply is
required, this is set to 0.
