Increasing output gradi-
ent
If the applicable grid code requires the active power response to set point by a defined gradient or settling time, the de-
vice can be configured to comply with this gradient. It is also possible to implement the gradient in the plant control sys-
tem. This second solution must be applied for all other inverters.
10.2.3 Voltage-dependent power reduction P(U)
If it is not possible to compensate adequately for voltage increase in the upstream distribution network by consumption
of reactive power, it may be necessary to curtail the active power. In this case, P(U) control is available for making opti-
mum use of the capacity of the upstream grid.
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. The P(U) control is implemented as an absolute power limit. The actual power of the inverter may vary
freely below this limit based on possible fluctuation of the available power or set point, but will never increase above the
absolute power limit.
[See figure 87 [} Page 88] and [See figure 88 [} Page 88] are two example configurations. In case of the Figure 1 with-
out hysteresis the function is activated once the voltage exceeds the configured voltage of data point 1 (dp1). The power
limit follows the characteristic, a straight line between dp1 and dp2. The function is deactivated once the voltage falls be-
low dp1. In case of [See figure 88 [} Page 88] the function is activated once the voltage exceeds the configured voltage
of dp2. dp1 is not activating the function in this case as the power limit remains at 100%. The power limit follows the
characteristic, a straight line between dp2 and dp3, but due to the activated hysteresis, the power limit is not increased at
falling voltage. The function is deactivated once the voltage falls below dp1.

Description
If the Timeout is set to 0 seconds, the
transmitted power limit is permanently
maintained, even in the event of a com-
munication failure.
Note: When the unit is restarted, the
Timeout is reset to the set fallback
time.
1 – 65534 [% Determines the dynamic behaviour in
/min] the event of a change in the active
lim
power set value. The active power is
changed with the specified gradient.
NOTE: The gradient is overlaid
with the settling time.
