Example 4: Setups AUS/NSZ
2020
Description of the parameters
-
"P(f) Mode": On (with Hys-
teresis)
-
"Active Grid Support": On
-
Battery is active
(1) Momentary effective power when the
respective "Activation Threshold" is
reached: 60 % of P
n
(nominal power).
(2) The gradient for power reduction in
generator-powered operation at over-
frequency results automatically from
the two set parameters "Activation
Threshold Overfrequency" and "Trans-
ition Frequency at Overfrequency"
(3) "Activation Threshold Overfrequency":
50.25 Hz
(4) "Transition Frequency at Overfre-
quency": 50.75 Hz
(5) The gradient for increasing the char-
ging power at overfrequency results
automatically from the two set para-
meters "Transition Frequency at Over-
frequency" and "Stop Frequency -
Overfrequency". Depending on the set
country setup, the power at stop fre-
quency refers to drawing 100 % from
the national grid. The parameter
"Power at Stop Frequency - Overfre-
quency" has no function in these
countries.
(6) "Stop Frequency - Overfrequency":
52.0 Hz
(7) "Upper Deactivation Threshold Over-
frequency": 50.0 Hz - When the grid
frequency returns to or below the set
limit value, the effective power may be
increased again.
(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.
