Under a specific grid code, after you set
Percents of trigger frequency
, the
characteristic curve takes effect only when the actual output active power of the inverter
is greater than the preset value.
8.3.6 cos(Phi)-P/Pn Characteristic Curve
If you do not need the SmartLogger to send remote reactive power control commands, you
can configure the characteristic curve on the SmartLogger as a substitute. The SmartLogger
delivers the values configured for the characteristic curve to the inverter, which then operates
in compliance with the configuration. The SmartLogger no longer adjusts the values.
Configure the characteristic curve under instructions from professionals to ensure that the
SUN2000 works properly.
The cos(Phi)-P/Pn characteristic curve control mode is to dynamically adjust the power factor
cos(Phi) in accordance with the P/Pn (%) based on the VDE-4105\BDEW German standard.
Set
Reactive power control mode
to
cos(Phi)-P/Pn characteristic curve
.
Figure 8-14
cos(Phi)-P/Pn characteristic curve
When you set the curve, ensure that the
P/Pn(%)
value of a point is greater than the
P/Pn(%)
value of the previous point. Otherwise, the
Invalid input
message will be
displayed.
The cos(Phi)-P/Pn characteristic curve can support a maximum of 10 valid points.
8.3.7 Q-U Hysteresis Curve (CEI0-16)
If you do not need the SmartLogger to send remote reactive power control commands, you
can configure the characteristic curve on the SmartLogger as a substitute. The SmartLogger
delivers the values configured for the characteristic curve to the inverter, which then operates
in compliance with the configuration. The SmartLogger no longer adjusts the values.
