Example 5: Setups AUS/NSZ
2020
Description of the parameters
-
"P(f) Mode": On (with Hys-
teresis)
-
"Active Grid Support": On
-
Battery is active
(1) Momentary draw (charging power of
the battery) when the respective "Ac-
tivation Threshold" (3) is reached:
80 % of P
n
(nominal power)
(2) The gradient for reducing the charging
power at underfrequency results auto-
matically from the two set parameters
"Activation Threshold Underfre-
quency" (3) and "Transition Frequency
at Underfrequency" (4)
(3) "Activation Threshold Underfre-
quency": 49.75 Hz
(4) "Transition Frequency at Underfre-
quency": 49.0 Hz
(5) The gradient for increasing the output
power at underfrequency results auto-
matically from the two set parameters
"Transition Frequency at Underfre-
quency" (4) and "Stop Frequency - Un-
derfrequency" (6). Depending on the
set country setup, the power at stop
frequency refers to 100 % output
power (nominal power of the inverter).
The parameter "Power at Stop Fre-
quency - Underfrequency" has no
function in these countries.
(6) "Stop Frequency - Underfrequency":
48.0 Hz
(7) "Lower Deactivation Threshold Under-
frequency": 50.0 Hz - When the grid
frequency returns to or above the set
limit value, the effective power may
return to the value before entering the
function.
(8) "Deactivation Time": 20 s - The fre-
quency must be in the valid range for
at least this time before the function
is terminated.
(9) "Return Gradient 1": Return to power
before entering P(f) in percent per
second.
