Other grid support functions effective on 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. Considering the fact that all KACO TL3 inverters have a semi-circular(PV)
full-circular(BI) 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
stricted in order to establish an apparent power reserve and ensure that the agreed reactive power can be delivered from
any active power operating point. The graphic [See figure 99 [} Page 96] shows the appropriate P-Q operating range
with a required example active power of 48% of the maximum apparent power of the plant or 43% of the maximum ac-
tive power of the plant.

The power reduction parameters can be adjusted in SunSpec model DID123. During this process, you should also check
whether internal and/or external power reduction is active.

Action in this menu/meaning
Dynamic grid support via fast feeding of residual current is activated on
voltage events with at least one phase/phase or phase/neutral conduc-
tor voltage outside the configured normal operating voltage range. Dy-
namic grid support via fast feeding ore residual current is deactivated
when the voltage returns to the reference operating voltage range.
0.1
0.1
The reactive power component of the fast feeding of residual current is
limited to permit a defined proportion of active power components.
1
If due to a voltage jump in accordance with formula (1) and the config-
ured dead band is activated, the dynamic grid support is deactivated via
fast feeding of residual current after the minimum support time elapses.
