Parameters For Reactive Power Control - Kaco blueplanet 29.0TL3 Serie Manual

Q(U)
In Q(U) 10 nodes mode, the set value of the reactive power is calculated continuously as a function of
the grid voltage. This function ensures that grid support is provided by reactive power as soon as the
voltage actually deviates from the target voltage. In this case, a characteristic curve is specified which
can be used to configure up to 10 nodes, value pairs for voltage and reactive power. Other parameters
allow to limit functionality and to limit activation to certain power levels as well as parametrize the tran-
sient response.
The positive sequence voltage is used to calculate the reactive power target value for three-phase
units.

Reactive power mode Under-excited relates to inductive load, over-exci-
ted relates to capacitive load.
Determines the dynamic behaviour in the event of a change in the cos φ
set value. With a change of the active power or the lock-in and lock out
voltage, the cos φ is changed according to a PT-1 characteristic curve
with a settling time of 5 Tau.
The control is activated above this voltage.
The control is deactivated below this voltage.

Power of the node as a percentage of the maximum power.
For the 1st node, the power must be 0%; for the last node, the power
must be 100%. The power values of the nodes must increase continu-
ously.
