Other grid-supporting functions that are effective in the case of active power

10.4.1 Permanent power gradient limitation
The maximum active and apparent power to be installed for a generation plant is agreed between the grid operator and
plant operator. The device capacity of a plant can be set to the exact agreed value using the S
sure that the load on the devices in the plant is uniform, we recommend distributing the performance reduction evenly
across all devices.
Some grid connection rules insist that the agreed reactive power be supplied from every operating point of the plant
without a reduction in the actual active power. Because KACO devices have the full P-Q operating range, a reduction in
the active power is, however, required during operation at maximum active power because an apparent power reserve is
not available. By adjusting P

Dynamic grid support through fast feeding of residual current activated
in the case of voltage events with a voltage change greater than the
dead band.
0.1
Dynamic grid support via fast feeding of residual current is activated on
voltage events with at least one phase/phase or phase/neutral con-
ductor voltage outside the configured normal operating voltage range.
Dynamic grid support via fast feeding of residual current is deactivated
when the voltage returns to the reference operating voltage range.

Standard: The reactive current according to the formulae (2) and (4) is
fed as additional reactive current. The means that sum of the pre-fault
and additional reactive current is fed in.
Only dynamic: The reactive current according to the formulae (2) and
(4) is fed in as absolute reactive current. This means that regardless of
the reactive current before the voltage event, only the reactive current
according to the formulae (2) and (4) is fed in during the voltage event.
Mode 1: When calculating the reactive current, the value of the dead
band is not subtracted from the amount of voltage change.
As such, formula (2) applies to overvoltage and undervoltage incidents.
Mode 2: When calculating the reactive current, the value of the dead
band is subtracted from the amount of voltage change. For overvoltage
and undervoltage events, formula (4) therefore applies:

The reactive power component of the fast feeding of residual current is
limited to permit a defined proportion of active power components.

If due to a voltage jump in accordance with formula (1) and the con-
figured dead band is activated, the dynamic grid support is deactivated
