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

10.4.1 Permanent power 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 and P
lim
commend 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 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 availa-
ble. By adjusting P
power reserve and ensure that the agreed reactive power can be delivered from any active power
operating point. [Ver figura 65: P-Q operating range with limited active power (Qmax=Smax≠Pmax) for
PV inverters [} Página 74] Displays the appropriate P-Q operating range with a required example acti-
ve power of 48% of the maximum apparent power of the plant or 43% of the maximum active power of
the plant.

10.4.2 Soft start-up / Power rampup

A soft start-up function is available to prevent the grid from being negatively impacted by a sudden in-
crease in feed-in power from the inverters.
When the inverter is activated or switched on, the increase in power is restricted by the set gradient. It
is possible to configure whether the soft start-up should occur every time the device is switched on,
only upon initial start-up each day or only upon start-up after the device has been switched off by grid
protection. Due primarily to the fact that there is the risk that many plants could increase their power
levels simultaneously after they have been switched off by grid protection, a soft start-up is usually
only required for start-up after a device has been switched off by grid protection.
