10.9.3 Active Power by Frequency P(f)
Menu
512 Power/Frequency
Description
Allows the statistics to be reset. The currency and credit per kWh
can also be configured.
This function alters the fed active power depending on the grid
frequency. If a starting frequency is exceeded, the fed active power
is limited. If a stopping frequency is exceeded, the active power is
no longer fed.
Behavior as per VDE AR N 4105 is described below.
Variant 1 : The grid frequency alters between f
Start
and f
Stop

Once the grid frequency exceeds the value f

, the value of the

being fed at this moment is automatically saved
and active power limiting is activated.
As long as the grid frequency stays above f
Start
and under f
Stop
, the
fed active power value runs along the gradients: Active power drops
with increasing grid frequency and increases with decreasing grid
frequency.
Variant 2 : The grid frequency exceeds f

Fig. 10.2: Function P(f), variant 2
When the grid frequency exceeds f
Start
but then remains under f
Stop
,
the solar inverter behaves as described in variant 1.
However, as soon as the grid frequency exceeds f
Stop
, the active
power feed is stopped.
Active power feed will resume once the grid frequency falls below
f
Start
. Once resumed, the active power will increase by 10% per
minute.
