Parameters For P(U) - Kaco blueplanet 29.0TL3 Serie Manual

10 | Specifications
P(U) control reduces the active power that is fed in as a function of the grid voltage using a prescribed
characteristic curve as a basis. P(U) control is implemented as an absolute power limit. The actual po-
wer of the inverter may vary freely below this limit due to a possible fluctuation in the available power
or the target value, but at no time increases above the absolute power limit.
[Ver figura 52: Example characteristic curve without hysteresis [} Página 66] and [Ver figura 53: Exam-
ple characteristic curve with hysteresis and a deactivation threshold below the activation threshold
[} Página 66] are two examples of configuration. In figure 1 without hysteresis, the function is activa-
ted as soon as the voltage exceeds the configured voltage of data point 1 (dp1). The power limit fo-
llows the characteristic curve, a straight line between dp1 and dp2. The function is deactivated as so-
on as the voltage falls below dp1. In [Ver figura 53: Example characteristic curve with hysteresis and a
deactivation threshold below the activation threshold [} Página 66], the function is activated as soon
as the voltage exceeds the configured voltage of dp2. In this case, dp1 does not result in activation of
the function because the power limit remains at 100%. The power limit follows the characteristic curve,
a straight line between dp2 and dp3. However, because hysteresis is activated, the power limit is not
increased when the voltage drops. The function is deactivated as soon as the voltage falls below dp1.

Action in this menu/meaning
F Activate the control process.
Off: Deactivates dynamic grid support using dynamic reactive current.
Dynamic grid support remains active on account of immunity to interfe-
rence.
Specifies the power reference for the characteristic curve. 100 % here
corresponds to the nominal power or the actual power at the time the
function was activated, the time when the voltage passes the configu-
red node.
F Select the voltage to be rated.
Specifies which voltage is evaluated in a three-phase system.
Off: In non-hysteresis mode, the active power is increased immediately
with dropping voltage.
On: In hysteresis mode, the power is not increased with dropping volta-
ge. .
